In the heart of Tokyo, Nihonbashi River lies hidden under a system of highway overpasses and the Sumida River is wide and commanding and it cuts through the city. With a variety of bridges, both rivers assert their own unique presence in the Tokyo cityscape. On our own river tour, we encountered the particular water and lightscapes surrounding the bridges and shores of each river. The newly built Nihonbashi Mitsui Tower next to the famous Nihonbashi Bridge. This is the first skyscraper in the Nihonbashi area and as the sun sets, the facade detail is elegantly illuminated. At the historical Nihonbashi District, a variety of lighting methods are on parade, but the highway overpasses keep most of the river hidden from view. Rumors of reconstructing the highway system underground would help revive the scenery along the Nihonbashi River. The main structure of the Chuo-Ohbashi Bridge is beautifully illuminated. The many bridges along the Sumida River compete with each other for top beauty marks, as each is illuminated in a multitude of colors.

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…

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…

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…

From up above Tokyo looks like an overturn jewelry box, the night streets glitter with lights and it a fairly beautiful sight. Once back on ground, the glitter has turned harsh. It is an economically advanced nightscape, an efficient nightscape with needless light and light pollution. An aerial view of Tokyo at night. The dark area in the center of Tokyo, the Emperor`s Palace, is surrounded by clusters of lights that resemble precious stones. From this view it is unclear where Tokyo begins or ends. The Tokyo nightscape is illuminated in bright white light. Mercury lamps and florescent lights in the background of Tokyo Tower control the nightscape of this city. Old-fashioned houseboats gather in the foreground of the Odaiba District and the Rainbow Bridge.
