In the middle of Tokyo is the Imperial Palace, a haven for runners and tourists, alike. The lighting in the palace outer garden and nearby Wadakura Fountain Park has been renewed and replaced with environmentally conscious LED fixtures. We surveyed the unique pocket of darkness that surrounds the Imperial Palace along with lighting environment of nearby parks and roads. Imperial Palace Outer Garden. The fancy pole lights in the outer garden are originally gas lamps, but the light source has been changed to high-pressure sodium lamps and now upgraded to LEDs. The average lux level is only 1-2lux along the paths lined with these LED fixtures, but inside the fixtures are 6, 26watt LED modules all pointed in different directions. This application helps to spread the light around without making a too bright, but comfortably dim atmosphere. Daikancho Street Daikancho Street runs along the north side of the palace grounds, is a much narrower street and pedestrian sidewalk compared with the rest of the facilities surrounding the palace. Along the tidy, hedged sidewalk, streetlights are placed at 3-meter intervals. Mostly for crime prevention, the lights are very bright and glaring. Ohtemachi Entrance The Ohtemachi Entrance area leads to an inner palace garden and is surrounded by a main arterial road on the outside, for a very open and accessible area. Most lighting is road lighting, mounted on 10-meter tall poles arranged down the middle of the street, but plenty bright…

A city for the young and young at heart, Shibuya. The area is composed of a mess of streets all with a different atmosphere, including a few main streets connected by narrower alleyways. Each street has developed its own personality and role, including lighting conditions to create the Shibuya night. From the scramble intersection in front of Shibuya Station, 3 distinctive roads, Dogenzaka, Center Gai, and Koen Dori radiate. After dusk, the lights come on and the personality of each street is even more clearly defined. As the title implies, Center Gai is the center of Shibuya geographically and caters to the young as the center for shopping and entertainment. This street is full of light. Each shop seems to be competing for the brightest facade with infinite amounts of luminous signage and advertising, creating a 3-dimensional playground. Dogenzaka is a festive street with a steady flow of pedestrians, but turn down one of the narrow side streets and the atmosphere changes immensely. The facades of many love hotels packed into the area are saturated with color creating a seedy blend of light and young couples prowling the Maruyama-cho area.

2023.07.19　Shunichi Ikeda + Masashi Kurobe + Yuta Shibata Shinjuku Kabukicho, Japan’s largest entertainment district, is a dazzling neon-lit labyrinth filled with restaurants, movie theaters, and amusement facilities. Its streets are teeming with people all night long. In recent years, however, the district has faced challenges, such as the growing presence of “Toyoko Kids” congregating in Cine City Square and engaging in criminal activities. Despite these issues, the opening of the new iconic Tokyu Kabukicho Tower has brought renewed attention to the area. As lighting detectives, we delve into the current state of Kabuki-cho, examining its lighting environment and cultural significance. ■Kabuki-cho Reborn: A Post-COVID Entertainment DistrictSeventeen years after our lighting survey in Shinjuku in 2006, Kabuki-cho has evolved from large-scale development into a global tourist hotspot. Though deserted during the 2020 state of emergency, the area is now vibrant again with the opening of Tokyu Kabuki-cho Tower. This survey revisits Kabuki-cho, comparing it with the previous survey and analyzing its changing lighting environment. ■Tokyu Kabuki-cho Tower: An All-Out Entertainment ComplexThe Tokyu Kabuki-cho Tower, a 48-story, approximately 225-meter-tall, super high-rise entertainment complex comprising a hotel, movie theater, theater, and more, opened in April 2023.Upon entering the building, I was overwhelmed by the countless glittering lights that filled the space. The small shops and narrow corridors were adorned with an excessive number of paper lanterns, creating an atmosphere reminiscent of an Asian festival. Outside, the building’s digital signage, facade indirect lighting, reflected…

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…

2021.10.27　Shunichi Ikeda + Erina Hosono + Namiko Watanabe About three weeks after the state of emergency in Tokyo was lifted, we conducted our first urban night walk survey since the COVID-19 outbreak, heading to Akasaka. The area between Akasaka and Akasaka-mitsuke features both traditional establishments such as atmospheric ryotei (Japanesestyle restaurants) and neon-lit entertainment districts reminiscent of Kabukicho. At the same time, Akasaka has gained recognition as a tourist destination due to redevelopment centered around Akasaka Sacas. We surveyed the nighttime environment of this area where tradition, business, and nightlife coexist. ■Aerial Nightscape of AkasakaThe central area of Akasaka lies roughly in the middle of the cluster of high-rise buildings. At first glance, the nightscape viewed from above gives a rather subdued impression, due to the lack of prominent building illuminations or large advertising towers. However, upon closer inspection, one can see clusters of commercial lights peeking through the gaps between buildings. While the limited presence of dramatic lighting or decorative illuminations may make it less visually striking, the overall effect is a calm and environmentally friendly nightscape. ■Akasaka Sacas AreaAkasaka Sacas, a multi-use complex directly connected to Akasaka Station, is usually frequented by businesspeople and shoppers. However, likely due to the lingering effects of the COVID-19 pandemic, the number of passersby during our survey was surprisingly low, which was unfortunate. The nighttime lighting around the base of the 179-meter-tall Akasaka Biz Tower is uniformly set to a relatively low…
