2022.11.4-5 Sachiko Segawa Surprisingly, this survey of the Sawara district marks the first time the Lighting Detectives have conducted an investigation within Chiba Prefecture. The team focused on an area designated both as an Important Preservation District for Groups of Traditional Buildings and as a Landscape Formation District. Here, the townscape of merchant houses, which flourished from the Edo period thanks to river transport on the Tone River, still remains. Located about 70 km from Tokyo Station and slightly inland from the Tone River, the Sawara district of Katori City once thrived as a merchant town, to the point it was said to rival Edo itself. However, the town declined during Japan’s period of rapid economic growth. Following a townscape survey in 1974, the value of its historic scenery was reappraised. Today, leveraging its convenient location—just two hours from Tokyo and one hour by train from Narita Airport—the area is being redeveloped as a tourist destination. For this survey, the team limited their scope to the townscape along the Ono River and conducted a nightscape survey. ■Uniquely Designed Lighting Fixtures From JR Narita Line Sawara Station, as we walked toward the Ono River, we were greeted by a bollard topped with a monkey. “Why a monkey…?” we wondered, but as we continued upstream along the river, we encountered bollards adorned with all sorts of figures: rabbits, carp, children, frogs, Ebisu, and more—each one different, with no two alike. These uniquely…

2023.01.20-01.22　Yuichi Anzai+ Chuanyi Liu　 ■Kozushima Village Kozushima is located about 180 kilometers south of central Tokyo with a population of about 1,800. The terrain is complex, with almost no flat land. The village is located in the center of the island at the foot of Mt. Tenjo. The impetus for the starry sky protection activities on Kozushima came from a comment made during a student internship program by the Tourism Foundation in 2016, that the night sky was as beautiful as a planetarium. The starry sky, a common sight on the island, has become a tourism resource. An island-wide effort to protect the sky began. Specific efforts include replacing streetlights and security lights with fixtures with 0% upward luminous flux and 2,700K color temperature, holding explanatory meetings for residents and regular workshops with experts to gain their understanding and cooperation in light pollution and starry sky protection activities, training islanders as guides, and holding star gazing events to protect the night sky from light pollution and communicate the appeal of the starry sky both on and off the island. The island is also working to protect the night sky from light pollution and convey the charm of the starry sky to the public. The “Light Pollution Prevention Ordinance to Protect the Beautiful Starry Sky of Kozushima Village,” which specifies the responsibilities of residents and businesses to prevent light pollution, will be enacted in 2019, and rules are being developed to…

The Television Broadcasting Tower looks down on the orange sodium lamps overflowing from the grid patterned streets of Sapporo. While on assignment in December we were able to view the multi-colored White Illumination set up along Ohdori Park and Sappore Eki Mae Street. Looking towards Ohdori Promenade from the JR Tower. Sapporo is a beautiful city at twilight with orange light from the streets to set off the blue-tinted snow-topped roofs. The tree-lined street, Sapporo Ekimae Avenue is a sight to see with its unique style of looping lights over tree branches. Visitors with cameras and mobile phones converge on the decorated Ohdori Promenade. Sapporo Television Tower, similar to Tokyo Tower and Nagoya Tower, and all designed by the same architect, is also illuminated with the same type of sodium lamp.

2024.9.9 Yonglin Ke + Kunzhi Jinag + Linxi Chen The brightness (luminance) of signage lighting is key to shape the overall lighting of a city. This survey conducted in Akihabara, a globally famous district, focused on the renowned Akihabara Electric Town (Chuo-dori), analyzing the evolution of the city’s lighting composition by comparing it to the survey from 19 years ago. ■Akihabara Electric TownAkihabara is the heart of electronics in Tokyo and a globally famous hub for otaku culture. While it is bustling with tourists daily, the colors of the signs, filled with anime and game culture, are much more diverse compared to upscale commercial areas like Ginza or other shopping districts. In 2020, Chiyoda Ward released guidelines for outdoor advertising and urban development, leading to changes in Akihabara’s streetscape. This survey investigates the current night view of Akihabara Electric Town, comparing it to a survey conducted 19 years ago. (Kunzhi Jiang) ■What kind of lights shape Akihabara?The main lighting elements in Akihabara’s key districts include streetlights, signage lighting, building façade lighting, and lighting from store entrances and spillover light.Compared to the picture from 19 years ago, the most noticeable green and red lights from EDION were not illuminated due to the store’s closure. The ONODEN sign is now an LED screen, and the surrounding lighting has a more subdued feel. Previously, the area behind the bridge was completely dark, but now, with the bright lighting from a drugstore’s interior and…

2023.01.26-01.29　Masafumi Yamamoto + Yuki Ito　 Okinawa is a place where diverse cultures and histories are intertwined. In Okinawa, each region has its own unique streetscape, and this is due to the fact that each region has a completely different historical background. The following is a simplified explanation of the historical background of each area. The Naha area was severely damaged in the war and was rebuilt; the Koza area was influenced by the U.S. military base and retains a strong American culture; and the Bise and Imadomari areas retain the traditional streets of the Ryukyu Islands. By comparing the light environment of each area, this survey sought to determine what kind of lifestyle culture and light features each area has, and what kind of light is unique to Okinawa. ■Sakae-machi MarketSakae-machi Market, located in Naha City, is a shopping street that was established during the postwar reconstruction period and has remained almost unchanged since then. Today, the market is a lively place where locals gather during the daytime, but at night it transforms into a more local haunt, drinking district that is quite different from the impression it gives during the daytime. The only light at night is from the taverns and the faint fluorescent lights in the upper part of the shopping street. (Floor illumination: approx. 20 lx) The illuminance alone gives the impression of dimness, but the actual atmosphere was not as dark as the impression given by…
