2022.10.27　Genki Watanabe+ Chuanyi Liu+ Yuki Ito This Tokyo night walk survey took place in Shimokitazawa, a neighborhood especially popular among young people. Known as one of Tokyo’s most culturally rich districts, the area is filled with vintage clothing shops, eateries, theaters, niche cinemas, and art galleries.The Lighting Detectives previously conducted a survey here in 2009. This time, we examined how the area has changed since the Odakyu Line was relocated underground. We also focused on the newly developed Shimokita Senrogai area, which opened on May 28, 2022, assessing its lighting design and comparing it with the older shopping streets to explore the contrast between new and traditional urban atmospheres. ■Map around Shimokitazawa Station With the Odakyu Line moved underground, a new neighborhood called Shimokita Senrogai was developed between Higashi-Kitazawa Station and Setagaya-Daita Station. Driven by the desire to support the community, redevelopment progressed step-by-step while listening to local residents’ voices. The entire area officially opened on May 28, 2022.Alongside the railway line, new facilities such as daycare centers, a hot spring inn, commercial spaces, student dormitories, and event venues were established. ■Development of Shimokita Senrogai The Shimokita Senrogai area we surveyed is a newly developed space created by moving the Odakyu Line underground. It was designed with the intention of reconnecting the northern and southern parts of the neighborhood that had previously been divided by the railway tracks, resulting in developments that encourage smooth pedestrian circulation throughout. The development features…

2025.09.04-09.08 Yonglin Ke + Masashi Kurobe The nights in Honolulu are a diverse blend of resort illumination, residential lights, torches, and night market glows. However, as the city develops, the starry sky is fading, raising concerns about the impact on the local ecosystem. Balancing urban growth with light pollution countermeasures remains a significant challenge. We conducted an on-site night walk survey to explore the balance between the city and nature and to evaluate the current lighting environment. ■Honolulu Honolulu, the capital of the U.S. state of Hawaii, is a prominent tourist destination in the heart of the Pacific Ocean. Simultaneously, it serves as the political and economic hub of the state. In this land where the sea, mountains, and urban areas sit in close proximity, the nightscape reveals a variety of expressions depending on the time and location—blending the glow of resort hotels, the soft lights of residences, traditional fire torches, and the vibrant lights of night markets. Furthermore, the combination of intense sunlight and a tropical climate creates a unique character within the city’s lighting environment. On the other hand, urban development and the growth of the tourism industry have negatively impacted the visibility of the starry sky and affected local ecosystems, such as migratory birds and sea turtles. While the state and city have begun implementing measures to reduce light pollution, finding a balance with the tourism industry remains a challenge. During this night walk survey, we investigated…

2022.07.11　Hikaru Kimura + Yonglin Ke + Xueying Piao Shibuya, known as a youth hub, began redevelopment in 2012, transforming into a business district with a cluster of new office buildings and commercial facilities. While many new restaurants have emerged, traditional drinking alleys remain intact. This survey investigates the contrasting night scenes of the new and old Shibuya. ■Overlooking Nightscape of ShibuyaFrom the Shibuya Scramble Square, the rooftop of Miyashita Park stands out prominently to the east of the central railway tracks. The warm glow along the podium belongs to Shibuya Yokocho (alley). Nestled beside the pitch-black railway tracks and appearing as a dotted red line is Nonbei Yokocho. Viewed from above, Nonbei Yokocho exuded a soft, flickering light, resembling candles, in contrast to the lively and vibrant atmosphere of Shibuya Yokocho.The overall nightscape, divided by the Yamanote Line tracks, presents a striking contrast: the western side is dominated by tall buildings, densely packed with billboards and advertisements, exuding the lively energy of a traditional entertainment district. The eastern side, on the other hand, has fewer billboards and subdued signage, giving it a unified and calm appearance.I wonder if Shibuya will eventually become a more standardized urban landscape, much like its eastern side. Personally, I felt the bustling, nostalgic charm of the western side embodies the true spirit of Shibuya, and it’s something worth preserving. (Yonglin Ke) ■Shibuya YokochoRAYARD MIYASHITA PARK, a new landmark in Shibuya, features Shibuya Yokocho, a 100-meter-long…

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…

Shiodome Sio-Site was a joint public and private sector redevelopment project completed in 2006. In nearby Shinbashi, eateries and bars built under and into the brick structure of the elevated railway tracks during the Meiji era have become a famous cityscape of this area. We set out to discover what kind of lighting environment exists in this conflicting neighborhood of Tokyo. Red lanterns, single light bulbs hanging under the eaves, colorful luminous signage…All the lighting is warm and inviting. The lighting environment along the streets of Shinbashi is wide and varied, but somehow closes the distance between strangers. Lighting for an elevated pedestrian deck connecting high-rise buildings in the area. The warm colored lighting creates a comfortable atmosphere for a nighttime stroll. The Shiodome high-rise buildings are not showy, and along with the interior office lighting, only a few have facade lighting on the building crowns.
