Modern Kagurazaka still conveys the atmosphere of its once flourishing Edo Era streets. Old Japanese restaurants and bars line the narrow alleyways and with softly glowing lantern light and welcome signs to complete the scene, one forgets that this is Shinjuku Ward in the middle of Tokyo. In this historical neighborhood warm lantern light is all but a natural presence. Compared to the white lights of Ikebukuro and Shinjuku glowing brightly in the distance, Kagurazaka is submerged in darkness. Buildings in Kagurazaka are lower and lower color-temperature light also peaks out from the many alleyways. Kagurazaka Street, running down the center of this neighborhood, is the only really bright spot, except for the lights reflecting off the canal along Sotobori Street. A prized neighborhood for shopping and entertainment during the Edo period, the historical Kagurazaka Shopping Street is a 700 meter long living time slip. New and old shops are jumbled together along the street with specially designed, lantern-like street lights placed at intervals along the edge of the sidewalk. From Kaguraza`s main street several narrow alleyways lead to the interior of the neighborhood where the scale of lighting is downsized to human proportions. Outside restaurants on Hyogo Yokocyo, one of the more famous back streets, softly glowing lanterns light the entrance and also reflect of the cobbled street and traditional-style fence for a very old Japanese atmosphere.

Kichijoji is an area of Tokyo where a variety of elements are compressed together to create this unique neighborhood. However, even though it seems to be a mixture of “stuff” the area is well planned and organized. Public and private organizations have aggressively worked together in city planning and we surveyed the area to discover what kind of lighting environment or rules they have advised. Starting on the north side of the station, a commercial area, we then moved to the south side of the station and Inogashira Park and the alleyways that connect the park and station. North Side of the Station The lighting along the covered arcade shopping streets, Sun Road and Diamond Street, are LEDs, creating a modern atmosphere, but down some of the narrower alleyways, like Harmonic Alley, the lighting is retro for an exciting nightly stroll. Park Street The main street from the station to Inogashira Park is a narrow 3-meter wide street lined with small cafes, bars, and recycled clothing and nick-nack shops. Restaurant and shop lighting is a warm 3000k for a comfortable atmosphere, but most street lighting spills out from the entrance to these restaurants and shops. Once they are closed for the night the street is very dark. Inogashira Park Equip with solor panels, tall metal halide streetlights record 331lx inside the park. However, the average lux level inside the park is about 30lx. The streetlights are too bright, and ruin…

The Diversity of Condominium Lighting in the Tokyo Area Condominiums play a leading role in housing for the Tokyo Area. As the city grew, busy shopping, business, and entertainment districts are supported by the residences, which live in densely populated residential areas. As the population density increased so did the proportion of condominiums for housing. According to reality statistics, condominiums account for 70% of the housing within the 23 wards of Tokyo. For this survey we stepped away from the bustle of the big city and investigated 3 relatively large, densely populated condominium complexes. The three areas all have a different history and commuting distances from the center of Tokyo. What can we discover about the lighting environment of these three totally different condominiums and the surrounding residential area? Toyosu Once an industrial area built on reclaimed land, housing redevelopment started in 2003 and the first of several residential blocks was completed in 2006. Toyosu is a “new city”, built from scratch and popular with younger families and couples. The number of condominiums is astounding, but the development is not just large, but a luxurious residential area as well. 　 Color temperature viewed from the condominium windows: Orange: 80% White: 16% Bluish: 4% The tower condominiums are immediately visible upon leaving the station. Relatively close to the center of Tokyo, these tower condominiums were built during a boom in condominium real estate. Each tower has a luxurious entrance lobby and…

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…

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…
