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.

Tokyo Survey: Tsukuda / Tsukishima 2019.11.18　　Kyoko Takubo+Yuichi Anzai+Namiko Watanabe An overview of Tsukishima. In contrast to the bright large city buildings, the small alleys and storefronts don’t leak much light Tsukuda is an fisherman island made in Edo-period. Tsukishima was landfilled in Meiji era and now there are still many row houses and small alleys. While the port area of Tokyo is going through mass redevelopment, we investigated the lighting environment of this area filled with intermingling old town houses and large city buildings. Tsukuda Tsukuda 1Chome Mainstreet. Children playing outside the old candy store Tsukuda 1 Chome Mainstreet is mainly lit with mercury lamps Tsukuda Machikado Museum. Its lit with LED3000K with about 134lx. Our investigation started by taking an overview photo from a tall building from the other side of the river. With the hustle and bustle bright lights from the Central area’s cityscape, there was one part that was dark- that is our target of this investigation, Tsukuda・Tsukishima. The dark patch from this area is even more pronounced as it is surrounded by the bright city lights all around.   As we get back on the ground, we headed towards Tsukuda 1 chome (Old Tsukuda Island) Mainstreet. On our way we saw the mercury lamp streetlights (4500K) emitting some green tinted white light. The average brightness was around 11lx. In the day you could still see a nostalgic scene with children playing outside the old candy store…

City Survey: Tsukiji, Tokyo 2017/12/14,2018/01/12　　Nemoto Isao + Masafumi Yamamoto　 Night view from the opposite shore of Tsukiji, across the Sumida River. Tsukiji Market on the middle, Tokyo Tower and Tsukiji Bridge on the left, and Kachidoki Bridge on the right. In this Tsukiji survey, we visited the inner market, where mainly wholesale is taking place, the outer market, where visitors can shop and eat, and also the Tsukiji Honganji temple and the Kachidoki Bridge which are popular spots for tourists. ■Luminous Environment around Tukiji Fish Market From the Kachidoki area on the opposite side of the Tsukiji fish market, you can overlook the entire view of the market, buildings such as Kachidoki Bridge and Tokyo Tower across the Sumida River. While we notice white light that comes from the market and surrounded buildings, the warm-colored light of incandescent lamps emitted from the fish handling facility facing the Sumida River on the opposite shore. This view is quite impressive, and creates an emotional and beautiful view during the night.This warm light from the market brings the sense of the history of Tsukiji rooted in this area for a long time. In contrast, the white light emitted from the group of high-rise buildings in the background seems to symbolize the momentum of the rapidly evolving city. Outside the market, there are more than 400 shops, and many shops still remain open after evening.Various light sources and lighting fixtures are used in each…

Roppongi has many faces including, an entertainment district with a foreign twist, new offices for daily business, and is developing as a center for the Tokyo art scene. The Lighting Detectives sped around on their bikes in April to discover what kind of light exists in this multi-functional area. The presence of the entertainment district is strongly felt at Roppongi intersection. Most people recognize this intersection as the center of Roppongi, but in recent years new development has created two new areas of focus, leaving the center of Roppongi very ambiguous. Points of reference include Mori Tower, Midtown Tower, Tokyo Tower and the metropolitan expressway, that cuts through, dividing this area of Tokyo. Large-scale luminous signage and a collage of other miscellaneous lighting dominate the view. Looking toward Roppongi from Aoyama Cemetery. The 3 towers that stand pronounced over Roppongi are a product of power and force, but appear alien in this setting. The towers look close and, yet, far off, as this scene can play tricks on your eyes.

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…
