2025.06.26 Yumi Honda +Qiaoxi Wang+ Momoe Nomura We observed and recorded the nighttime light environment of the newly developed commercial complex Senkyaku Banrai in the Tokyo Bay Area and its surrounding public spaces (green plaza, station area, and Gururi Park). We conducted a multifaceted analysis, including the placement of lighting fixtures, illuminance, and the impression of the space, to determine how light affects the atmosphere of the facility and the city in the Toyosu area, which is being developed as a tourist hub. The Toyosu area is a point of interest where the latest urban spaces and the lively atmosphere of shitamachi (old downtown) coexist due to redevelopment. We walked through the area around Toyosu Market Station, the green plaza, and Gururi Park, observing how light design impacts the impression, comfort, and safety of the town. ■Senkyaku Banrai Senkyaku Banrai is a commercial facility that opened in 2024 next to the Toyosu Market. It’s a spot where both tourists and local residents can enjoy the array of restaurants and souvenir shops. Through architecture and lighting design incorporating traditional Japanese motifs, it exudes a uniquely Japanese warmth and vitality, even within the contemporary urban nightscape. The lighting plan inside the facility is unified, as befitting a new commercial complex, and was designed with both aesthetic appeal and functionality in mind. The main path lighting uses warm, incandescent colors, creating a nostalgic atmosphere reminiscent of a Showa-era shopping street. This fosters a…
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…
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…
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.
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…
