During the Edo period, it prospered as a post station along the Tokaido route. The city\u2019s name originates from the markets that were held on days ending in \u201c4.\u201d<br>After World War II, Yokkaichi grew as an industrial city with the construction of a petrochemical complex during Japan\u2019s period of rapid economic growth. However, air pollutants emitted from the complex caused a serious pollution-related illness known as Yokkaichi asthma.<br>Today, the city has regained a comfortable living environment. Residential areas, shopping streets, and everyday life now extend right alongside the industrial zones.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped

class=\"wp-element-caption\">The Map of Factory Nightscape Spots<\/figcaption><\/figure>\n<\/div>\n\n\n<p>\u25a03D Factory Nightscape<\/p>\n\n\n\n<p>Yokkaichi, with its history of industrial development, began drawing attention during the early 2000s factory nightscape boom. The expansive factory nightscape of the Yokkaichi petrochemical complex, which stretches about 10 kilometers north to south, is counted among Japan\u2019s five greatest factory nightscapes.<\/p>\n\n\n\n<p>What makes it especially unique is that the nightscape can be viewed from the sky, land, and sea\u2014earning it the nickname \u201c3D Nightscape.\u201d Particularly photogenic views of the factory nightscape have gained significant popularity. From the perspective of the Lighting Detectives, we conducted a survey of Yokkaichi\u2019s factory nightscape as part of our exploration into lighting in industrial cities.<\/p>\n\n\n\n<p>\u25a0Luminaires in the Factory Nightscape<\/p>\n\n\n\n<p>Most factory nightscape photos commonly seen in the media capture entire buildings or cityscapes, but opportunities to closely observe the actual lighting equipment used at factories are rare.<br>While there is a common image of orange sodium lamps being used, our on-site observations revealed that white LED light sources and fluorescent lamps are actually more prevalent. The lighting equipment lacked any beam control features, likely because safety and work efficiency are prioritized.<br>Since there\u2019s little consideration for glare or light pollution, the lighting felt extremely intense when viewed up close. When approaching the factories, we found that the lighting fixtures had no optical control, and the white light appeared overwhelmingly bright.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-large is-resized\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-scaled.jpg\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-1024x576.jpg\" alt=\"\" class=\"wp-image-40150\" style=\"width:429px;height:auto\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-1024x576.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-300x169.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-768x432.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-1536x864.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-2048x1152.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSC8398-800x450.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Up close, the lighting fixtures lack light distribution control, and the white light is very glaring.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>\u25a0The \u201cExtraordinary\u201d Becomes Ordinary<\/p>\n\n\n\n<p>Lighting installed throughout the area casts a stark glow over the factories, emphasizing their distinctive shapes and highlighting the unique character of each facility. In photos, these scenes often appear to create a surreal, almost fantastical world. However, seeing the nightscape in person revealed both awe-inspiring views like those captured in photos, and others that felt more like selectively framed scenes designed for visual impact.<br>Factory nightscapes are often described using words like \u201cfantastical\u201d or \u201cextraordinary,\u201d evoking a sense of wonder far removed from everyday life.

However, the factory nightscape in Yokkaichi\u2014stretching across a 10-kilometer-long complex\u2014maintains a continuous glow that extends far into the horizon. Lighting fixtures without beam control cast light in all directions, contributing to glare and light pollution. Ironically though, this kind of lighting, which might be considered uncomfortable up close, creates a stunning nightscape when viewed from above, seemingly captivating all who see it.<\/p>\n\n\n\n<p>From the observatory in Tarusaka Park, we could view both the Yokkaichi petrochemical complex near the sea and the inland city area at the same time. While the view wasn\u2019t as sharp to the naked eye as in photographs, the stark difference in brightness between the complex and the city was unmistakable\u2014clearly demonstrating the sheer intensity of the factory lighting.<br>What stood out most in Yokkaichi\u2019s overhead nightscape was the horizontal divide of light and shadow, separating the complex from the cityscape.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-4 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-scaled.jpg\"><img decoding=\"async\" width=\"2560\" height=\"1920\" data-id=\"40163\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-scaled.jpg\" alt=\"\" class=\"wp-image-40163\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-scaled.jpg 2560w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-300x225.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-1024x768.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-768x576.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-1536x1152.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-2048x1536.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-200x150.jpg 200w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-_DSF7858-800x600.jpg 800w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><\/a><figcaption class=\"wp-element-caption\">The dazzling factory nightscape viewed from the Yokkaichi Port Building. <br>Each light is intense and stretches for about 10 kilometers<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<p>\u25a0Lighting Environment in the City Center<\/p>\n\n\n\n<p>We visited the city center around Kintetsu Yokkaichi Station. The area had undergone redevelopment, and along Chuo Center Street, improvements were being made to the bus terminal and circular pedestrian bridge.<\/p>\n\n\n\n<p>When heading west from the station, two rows of streetlights, one for the road and one for the sidewalk, stand in continuity. The color temperature was unified at 3000K, creating a cohesive landscape throughout the space. The lighting was thoughtfully planned, and I was surprised by how a calm lighting environment was maintained around the busy station area, while still ensuring the necessary illumination for the roadway.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154.jpg\"><img decoding=\"async\" width=\"2016\" height=\"1512\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154.jpg\" alt=\"\" class=\"wp-image-40153\" style=\"width:454px;height:auto\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154.jpg 2016w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154-300x225.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154-1024x768.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154-768x576.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154-1536x1152.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154-200x150.jpg 200w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/s-IMG_2154-800x600.jpg 800w\" sizes=\"(max-width: 2016px) 100vw, 2016px\" \/><\/a><figcaption class=\"wp-element-caption\">The well-maintained Chuo-dori features two rows of streetlights, uniformly 3000K, with indicators at the top that could be mistaken for traffic signals.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>On top of the futuristic-looking pole lights, I noticed lights that resembled indicators, glowing green when viewed from the east and purple when viewed from the west. I was unsure of the purpose of these indicators and was slightly concerned that they might be mistaken for traffic signals.<\/p>\n\n\n\n<p>The east side of the station appeared to be still under development. Compared to the well-developed west side, there were more noticeable imperfections. These included streetlights with one bracket not lit, mismatched color temperatures of the streetlights, and a broken shade on one of the lights. I hope these issues will be addressed in future improvements.<\/p>\n\n\n\n<p>\u25a0Yokkaichi Ichibangai Shopping Street<\/p>\n\n\n\n<p>We walked through the bustling Yokkaichi Ichibangai shopping street, the liveliest area in the city. When we first visited the main street during the day, it was devoid of people. The soft natural light filtering down from the arcade roof and the vast, empty space gave off an oddly mismatched sense of calm and eeriness. However, when we returned after dark, the street had transformed into a vibrant, almost theme park-like spectacle.<\/p>\n\n\n\n<p>At the far end of the street, I discovered arcade pillars adorned with a variety of lighting\u2014floodlights for color lighting from above, spotlights illuminating the ceiling, spotlights lighting the floor, and bracket lighting. The street, adorned with lights just before Christmas, created a lively and cheerful scene with people bustling about. In the adjacent Suwa Park, an illumination event was taking place. Though imperfect and scattered in places, the lighting truly brought the area to life.

The factory&#8217;s nighttime presence, often seen as a prime example of light pollution, somehow evokes a nostalgic and romantic atmosphere. I had intended to explore the reasons behind this, but before I knew it, I was fully immersed in photographing the nightscape.

We visited her lighting design office in Fukuoka City, which felt as comfortable and refined as an art museum. There, we had the opportunity to hear a wide range of storie\u2014from the time she spent developing the guidelines to her mindset as a lighting designer.<\/p>\n\n\n\n<p>One thing that left a lasting impression was her comment that guidelines shouldn\u2019t become manuals, but rather serve as guidebooks. It became clear that her approach, rooted in deep empathy for the local community, allowed her to foster unique charm through the application of the guidelines in ways that reflect the distinct character of each area.

Immediately after exiting the ticket gates, we were greeted by a large poster boldly promoting Kitakyushu as &#8220;A City of Beautiful Nightscapes,&#8221; leaving a strong impression on visitors and raising our expectations for the investigation to come.<br>While more foot traffic could be found on the Kokura Castle side facing the downtown area, the Shinkansen side of the station also featured an eye-catching lighting plan accented with greenery. <br>A landmark 30-meter lighting tower stood prominently at the Shinkansen exit, illuminating the station rotary. The overall lighting was not overly bright, but instead struck a balance that conveyed a sense of safety. The pedestrian deck leading to hotels and the exhibition hall featured windows shaped like Shinkansen train cars, softly lit by indirect lighting\u2014an imaginative and playful touch. On the deck, areas with benches were lit only by bench lighting, creating a calm and restful atmosphere. In contrast, busier areas with roofs were well-lit with base lighting, resulting in a space with clear distinctions and thoughtful layering.<\/p>\n\n\n\n<p>After moving to the Kokura Castle Exit and heading south along Heiwa Street, we arrived at a bustling downtown area. A monorail runs down the center of Heiwa Street, with an elevated track structure continuing along the way. The viaduct was lit with soft-colored uplighting, and the road lighting combined powerful fixtures mounted directly under the elevated track with standard pole lights. This resulted in an evenly illuminated space.<\/p>\n\n\n\n<p>Upon reaching Heiwa-dori Station on the monorail line, we found the station building bathed in a<br>purplish-pink light. However, the actual impression differed from photos we had reviewed beforehand. Upon closer inspection, we noticed a significant layer of dust had accumulated on the lighting fixtures. This likely caused a reduction in brightness and altered the overall appearance.<br>This experience reaffirmed the importance of regular maintenance and accessibility, especially<br>when using upward-facing fixtures in areas with heavy traffic.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-7 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-scaled.jpg\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"40276\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-1024x683.jpg\" alt=\"\" class=\"wp-image-40276\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/8635a171791e631e5e77173f74db3f36-800x533.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Under the Heiwadori Station Overpass.

Among them, Uomachi Gintengai Street, located west of Heiwa-dori Station, is known as Japan\u2019s first covered shopping arcade. Its arched and high-ceilinged arcade allows ample natural light during the day, and at night, linear lighting and downlights ensure the area remains well-lit. The space felt open and bustling, without any sense of confinement.<br>A short distance away lies Tanga Market, which has been operating since the Taisho era. Although a major fire struck the area in 2022, many stores continue to operate at a nearby openair market. Tanga Market also has an arcade, but compared to Uomachi Gintengai Street, the ceiling is lower. While the floor illuminance was sufficiently maintained at around 200 lux, the lack of open stores at night made the space feel darker. In contrast, Uomachi Gintengai Street felt more vibrant due to a combination of signage lighting, illumination from open shops, and a brightly colored ceiling that all contributed to a lively atmosphere.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-8 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-scaled.jpg\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"40261\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-1024x683.jpg\" alt=\"\" class=\"wp-image-40261\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d1224e4647eb7e006eb827efcbfa890e-800x533.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Tanga Market. <br>The ceiling is also dim, making the entire space feel dark overall.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a.jpg\"><img decoding=\"async\" width=\"1024\" height=\"768\" data-id=\"40265\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-1024x768.jpg\" alt=\"\" class=\"wp-image-40265\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-1024x768.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-300x225.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-768x576.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-1536x1152.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-200x150.jpg 200w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a-800x600.jpg 800w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/d159f639ea66e96629ed585a53e50c0a.jpg 2016w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Uomachi Gintengai where there is foot traffic late into the night.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<p>\u25a0Kokura Castle and Its Surroundings Steeped in History and Elegance<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225.jpg\"><img decoding=\"async\" width=\"1512\" height=\"2016\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225.jpg\" alt=\"\" class=\"wp-image-40279\" style=\"width:401px;height:auto\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225.jpg 1512w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225-225x300.jpg 225w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225-768x1024.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225-1152x1536.jpg 1152w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/e9af5612e256a8d440f42f77e8d32225-800x1067.jpg 800w\" sizes=\"(max-width: 1512px) 100vw, 1512px\" \/><\/a><figcaption class=\"wp-element-caption\">Kokura Castle beautifully reflected in the moat<\/figcaption><\/figure>\n<\/div>\n\n\n<p>After passing through the shopping arcade, we crossed the Murasaki River. Despite its short length, the river is spanned by as many as ten bridges, and a phased plan to install new lighting on several of them is currently underway. The river serves as a true \u201cnexus of the city,&#8221; connecting Kitakyushu&#8217;s cultural district with its bustling downtown area. At the time of our visit, remnants of Christmas illuminations were still visible, and there didn\u2019t seem to be a cohesive lighting scheme across the bridges. However, it is hoped that future lighting will highlight the unique character of each bridge, contributing to a more attractive and unified riverfront space.<\/p>\n\n\n\n<p>On the other side of the river stood Kokura Castle, beautifully illuminated. The surrounding lighting followed the theme of \u201clight that evokes historical ambiance,\u201d gently highlighting features such as white plaster walls and traditional namako-style walls. As a landmark, Kokura Castle is brightly lit in pure white, envisioned as \u201ca castle reflected on the water that remains even with eyes closed.\u201d From a distance, the intense light caused some glare, but seeing the castle\u2019s reflection in the moat clarified the purpose of such brightness. The lighting was provided by floodlights mounted across the moat and on adjacent city buildings. The pathway in front of the castle was lit to a minimal level of 3 lux, but the vertical surfaces of the castle and opposite white walls were sufficiently illuminated, ensuring no sense of darkness or insecurity.

White streetlights line the waterfront.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>Although the weather was unfortunate with a light layer of snow covering the ground, the observation deck still offered a panoramic view stretching from Mount Sarakura to the Hibikinada Sea. The most striking feature in the scenery was the Wakato Bridge, illuminated in a vivid red. It is said that the two main towers are designed to resemble burning torches, and indeed, they conveyed a sense of strength and elegance that emphasized the suspension bridge\u2019s structure. The red hue appeared deeper and more vivid than during the daytime due to the lighting color, leaving a lasting impression of an elegant and dramatic crimson\u3000scene unique to the night.<\/p>\n\n\n\n<p>Beyond the city lights of the Tobata and Kokura areas, which we had crossed by boat, rows of smokestacks could be seen. Streetlights along the bay were scattered across the tangled waters between the factories. The deep red Wakato Bridge tied together this somewhat surreal scene where residential lighting and industrial nightscapes coexist side by side. It was a night view full of presence, offering a vivid experience of Kitakyushu\u2019s unique charm, where diverse urban landscapes exist in close proximity.<\/p>\n\n\n\n<p>\u25a0Drawn by the Warm Lights of Ogai Street<\/p>\n\n\n\n<p>After returning to central Kokura, we headed toward the eastern side of Heiwa Street. The warm liveliness of Ogai Street welcomed our cold bodies after being chilled at the snow-dusted observation deck. As soon as we entered the street, we noticed that streetlights of a unified design stretched all the way down the road. At a cozy height of around three meters, the lantern-shaped heads emitted a gentle glow, casting light even onto nearby buildings. Together with functional footlights at ground level, the warm-colored lights formed a continuous path that guided people deeper into the street.<\/p>\n\n\n\n<p>Even the shop sign lights and the lights under the eaves, though individually varied, seemed harmoniously integrated into the lively atmosphere, thanks to the continuity of the street lighting. However, in areas where old white security lights \u2014 likely installed before the streetlights were upgraded \u2014 still shone overhead, the warm ambiance was noticeably disrupted. This highlighted the challenges of phased public lighting improvements.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-11 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/f4139b0f29056ee1cf93075d66d5b74d.jpg\"><img decoding=\"async\" width=\"717\" height=\"572\" data-id=\"40278\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/f4139b0f29056ee1cf93075d66d5b74d.jpg\" alt=\"\" class=\"wp-image-40278\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/f4139b0f29056ee1cf93075d66d5b74d.jpg 717w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/f4139b0f29056ee1cf93075d66d5b74d-300x239.jpg 300w\" sizes=\"(max-width: 717px) 100vw, 717px\" \/><\/a><figcaption class=\"wp-element-caption\">Ougai Street is brightly lit all the way down <br>by shopfront lights and street lamps.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-scaled.jpg\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"40275\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-1024x683.jpg\" alt=\"\" class=\"wp-image-40275\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/34dc1a82cbe60710b6fc909de3f4ada2-800x533.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Street lamps emit a warm glow <br>through their lantern-style tops and footlights<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<p>\u25a0Sakaimachi Park: A Node Connecting the Cityscape<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/b66b1701bf43e1f4c09069214537103a.jpg\"><img decoding=\"async\" width=\"716\" height=\"584\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/b66b1701bf43e1f4c09069214537103a.jpg\" alt=\"\" class=\"wp-image-40280\" style=\"width:453px;height:auto\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/b66b1701bf43e1f4c09069214537103a.jpg 716w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/b66b1701bf43e1f4c09069214537103a-300x245.jpg 300w\" sizes=\"(max-width: 716px) 100vw, 716px\" \/><\/a><figcaption class=\"wp-element-caption\">At Sakai-machi Park, the entrance features lantern-shaped bollards, giving visitors a festive feeling as if entering a celebratory space.<\/figcaption><\/figure>\n<\/div>\n\n\n<p>At the end of a narrow alley continuing from Ogai Street, we arrived at the plaza of Sakaimachi Park, which faces a major urban road. From low-positioned lighting such as ground projections and under-bench lights, to illuminated bollards, tree uplighting, and the lit-up surrounding buildings used as borrowed scenery, a layered sense of brightness was achieved, giving the space an expansive feel. It served as a junction connecting areas of the cityscape with varying scales. In contrast to the high color temperature, white streetlights of the adjacent Komonji Street, the park was uniformly lit with warm, incandescent-colored light, creating a comfortable and inviting atmosphere.<\/p>\n\n\n\n<p>\u25a0Well-Designed and Carefully Maintained Street Lighting<\/p>\n\n\n\n<p>On wide multi-lane roads, there was a clear consideration in differentiating the types of streetlights used to separate pedestrian areas from the roadway. In some areas, we observed public streetlights equipped with additional lighting fixtures that illuminated the fa\u00e7ades of nearby buildings, revealing an intention to design streetlights not only to light the roads but also to enhance the surrounding spatial environment as a whole.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-12 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-scaled.jpg\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"40260\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-1024x683.jpg\" alt=\"\" class=\"wp-image-40260\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/0b502b4d130049008cbaf5dd88a7aa88-800x533.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Fixture height and light distribution vary <br>between the roadway and sidewalk.<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-scaled.jpg\"><img decoding=\"async\" width=\"1024\" height=\"683\" data-id=\"40267\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-1024x683.jpg\" alt=\"\" class=\"wp-image-40267\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/c3d2fc74ad04916c892aa7cd20c8ce8a-800x533.jpg 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption class=\"wp-element-caption\">Sidewalks have 5-meter streetlights; <br>intersections feature building facade uplights.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<p>\u25a0Romantic Mojiko Retro<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-scaled.jpg\"><img decoding=\"async\" width=\"2560\" height=\"1707\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-scaled.jpg\" alt=\"\" class=\"wp-image-40273\" style=\"width:407px;height:auto\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-scaled.jpg 2560w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/1a76bf2baab4c729b6fa4fe0a7c7ecd5-800x533.jpg 800w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><\/a><figcaption class=\"wp-element-caption\">The station roof was illuminated by lights\u3000projected from surrounding buildings<\/figcaption><\/figure>\n<\/div>\n\n\n<p>On the final day of the survey, we extended our trip slightly from Kokura to the Mojiko Retro District. Upon arrival, we were greeted by the charming retro-style train station, heightening our anticipation. The compact area is lined with historic buildings, with the sea visible nearby. Just a short stroll through the town evokes a strong sense of nostalgia and atmosphere.<br>At night, a unified lighting design is applied to each building, using warm-toned lights such as incandescent-style lighting and sodium lamps that enhance the brick fa\u00e7ades. This created a warm and romantic nightscape that built on the daytime charm of the area.<br>From the observation deck on the 31st floor, we were able to take in a panoramic view of the Mojiko Retro District stretching to the Kanmon Strait. The townscape below was free from intense upward glare, and the streets were gently illuminated with warm light. The glow along the waterfront reflected off the surface of the water, creating a postcard-perfect night view.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><a href=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-scaled.jpg\"><img decoding=\"async\" width=\"2560\" height=\"1707\" src=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-scaled.jpg\" alt=\"\" class=\"wp-image-40266\" style=\"width:402px;height:auto\" srcset=\"https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-scaled.jpg 2560w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-300x200.jpg 300w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-1024x683.jpg 1024w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-768x512.jpg 768w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-1536x1024.jpg 1536w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-2048x1365.jpg 2048w, https:\/\/shomei-tanteidan.org\/wp-content\/uploads\/2025\/04\/02cd20bc54dee095782851c1eb4df76f-800x533.jpg 800w\" sizes=\"(max-width: 2560px) 100vw, 2560px\" \/><\/a><figcaption class=\"wp-element-caption\">The town\u2019s lighting is unified with a low color temperature<\/figcaption><\/figure>\n<\/div>\n\n\n<p>In some areas, certain spots appeared significantly brighter than their surroundings due to signage lighting installed on the upper parts of buildings reaching down to the ground. When we measured the illuminance levels along the streets, we found most areas averaged between 1 to 10 lux, with a maximum of under 20 lux. However, one spot registered approximately 120 lux, which felt overly bright for the ambiance of the area.<\/p>\n\n\n\n<p>Across the Kanmon Strait, the Shimonoseki side, with the sea in the foreground, appeared dimmer due to the distance. Nevertheless, the string of twinkling waterfront lights offered a glimpse into the life on the opposite shore and created a nightscape full of promise and allure.

This demonstrates Kitakyushu City&#8217;s strong commitment and proactive efforts to enhance urban development through effective use of its nighttime scenery.<br>Looking ahead, plans are underway to illuminate the ten bridges spanning the Murasaki River. The nightscape of Kitakyushu is set to evolve even further.
