The Television Broadcasting Tower looks down on the orange sodium lamps overflowing from the grid patterned streets of Sapporo. While on assignment in December we were able to view the multi-colored White Illumination set up along Ohdori Park and Sappore Eki Mae Street. Looking towards Ohdori Promenade from the JR Tower. Sapporo is a beautiful city at twilight with orange light from the streets to set off the blue-tinted snow-topped roofs. The tree-lined street, Sapporo Ekimae Avenue is a sight to see with its unique style of looping lights over tree branches. Visitors with cameras and mobile phones converge on the decorated Ohdori Promenade. Sapporo Television Tower, similar to Tokyo Tower and Nagoya Tower, and all designed by the same architect, is also illuminated with the same type of sodium lamp.

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…

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…

Bangkok, a city in a swirl of on-going change. In our previous survey of Tokyo’s Kanda River, we discover that the backs of buildings face the river creating and area of dark contrast in the middle of the city. But here along the Chaopraya River the opposite is true with the front facades lining the waterfront. Open-air restaurants and bars occupy the rooftops, as the spectacle of the city spreads out below. The Millennium Hilton, Bangkok, opened in May of 2006, is the first major hotel brand to open a hotel in the country in 20 years. The hotel boasts 543 riverfront rooms. With a UFO-like disk on top of the building, the cool-modern design stands tall among the neighboring structures. Along the riverfront, a private pier is provided for guests and dinners at the restaurant and bar. As river taxis come and go, the warm spots of light along the river reflect and shimmer on the water surface. Scirocco, one of many open-air restaurants, is approximately the same height as the special observation room at Tokyo Tower, 246 meters above ground, but without the glass barrier!. Without a glass window the lights of the city below seems so much more clear and real!! At the next table sat an older coupe that came to watch the sunset. The woman was surprised when presented with a big bouquet of flowers, undoubtedly a romantic gesture from her husband. A single candle…

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…
