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.

2022.10.27　Genki Watanabe+ Chuanyi Liu+ Yuki Ito This Tokyo night walk survey took place in Shimokitazawa, a neighborhood especially popular among young people. Known as one of Tokyo’s most culturally rich districts, the area is filled with vintage clothing shops, eateries, theaters, niche cinemas, and art galleries.The Lighting Detectives previously conducted a survey here in 2009. This time, we examined how the area has changed since the Odakyu Line was relocated underground. We also focused on the newly developed Shimokita Senrogai area, which opened on May 28, 2022, assessing its lighting design and comparing it with the older shopping streets to explore the contrast between new and traditional urban atmospheres. ■Map around Shimokitazawa Station With the Odakyu Line moved underground, a new neighborhood called Shimokita Senrogai was developed between Higashi-Kitazawa Station and Setagaya-Daita Station. Driven by the desire to support the community, redevelopment progressed step-by-step while listening to local residents’ voices. The entire area officially opened on May 28, 2022.Alongside the railway line, new facilities such as daycare centers, a hot spring inn, commercial spaces, student dormitories, and event venues were established. ■Development of Shimokita Senrogai The Shimokita Senrogai area we surveyed is a newly developed space created by moving the Odakyu Line underground. It was designed with the intention of reconnecting the northern and southern parts of the neighborhood that had previously been divided by the railway tracks, resulting in developments that encourage smooth pedestrian circulation throughout. The development features…

2023.01.26-01.29　Masafumi Yamamoto + Yuki Ito　 Okinawa is a place where diverse cultures and histories are intertwined. In Okinawa, each region has its own unique streetscape, and this is due to the fact that each region has a completely different historical background. The following is a simplified explanation of the historical background of each area. The Naha area was severely damaged in the war and was rebuilt; the Koza area was influenced by the U.S. military base and retains a strong American culture; and the Bise and Imadomari areas retain the traditional streets of the Ryukyu Islands. By comparing the light environment of each area, this survey sought to determine what kind of lifestyle culture and light features each area has, and what kind of light is unique to Okinawa. ■Sakae-machi MarketSakae-machi Market, located in Naha City, is a shopping street that was established during the postwar reconstruction period and has remained almost unchanged since then. Today, the market is a lively place where locals gather during the daytime, but at night it transforms into a more local haunt, drinking district that is quite different from the impression it gives during the daytime. The only light at night is from the taverns and the faint fluorescent lights in the upper part of the shopping street. (Floor illumination: approx. 20 lx) The illuminance alone gives the impression of dimness, but the actual atmosphere was not as dark as the impression given by…

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.

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…
