The Marunouchi district in the center of Tokyo has been transformed in recent years from a business and financial center to the latest redevelopment to intertwine commercial and office space. Our survey started in Marunouchi, as we closed in on the infamous Tokyo Tower to view the sprawling Tokyo nightscape. Marunouchi Central Street is enclosed on both sides by buildings all at the same height of 31 meters. Facade lighting and streetlights throw an even light over the street, creating a flat nightscape with no rhythm of light and shadow. Quite possibly occupying the staring role in the production of the Tokyo nightscape is the Tokyo Tower. The ironworks structure of this tower is illuminated from underneath, beautifully generating a glowing symbol for the city. At 250 meters, looking down on Tokyo from the tower is a beautiful site. Glare is blinding and there is no visible unified pattern to the lights of Tokyo, but lights twinkle all over the city and continue as far as the horizon. Things always look better from a distance and the Tokyo nightscape is one of them!
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…
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.
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…
Taking a drive along the Tokyo Metropolitan Expressway is a great experience in the sequence of Tokyo light. In one drive you can catch glimpses of Tokyo Tower in between buildings, awe at the endless Ginza neon signage, and hide in the dark shadows surrounding the emperor’s palace and Tokyo Bay. Close up lights zoom by, but in the distance light is scattered everywhere, creating a complex sequence of overlapping elements. Such a variety of light exists in Tokyo! Rainbow Bridge and Tokyo Tower, Dual Features of the Tokyo Night (Ariake JCT~Shibaura JCT) At night the Rainbow bridge is a bridge of light connecting the Bayshore Route and Tokyo mainland. As we drove across the bridge, the Tokyo Tower that seemed to twinkling in the far distance became a dominating presence. However, all of the distance lights of Tokyo were swallowed by the cluster of buildings waiting for us on the Shibaura side of the bridge. The Lights of the Tokyo Nightscape (Ohi JCT ~ Shibaura JCT) Working from Haneda towards the center of Tokyo, among the rough and tumble lighting for warehouses and factories, is warm light spilling from offices and condominiums. The expressway takes a dive under the Tokyo Monorail for a real peak at Tokyo-style building light and luminous signage. The Expressway in the Ginza Sky (Tokyo Expressway) The Tokyo Expressway is elevated in midair as it cuts through Ginza. Officially, it is not part of the…
