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.

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…

In front of the main gate to Senso-ji Shrine lies the neighborhood of Asakusa. One of Tokyo’s most popular entertainment districts, Asakusa flourished with kabuki, opera, and comic storytelling from the Meiji Era to the end of WWII. The Lighting Detectives discovered a variety of decorative streetlights and a lighting atmosphere fitting for this lively cultural destination. Upon entering the famous Kaminarimon, the Nakamise approach proceeds towards the shrine with bright-white, fluorescent-tube illuminated signage lining both sides. After navigating this corridor, walls of softly glowing lanterns come into view. The lanterns once lit with fire were replaced with incandescent bulbs and now fluorescent lamps. In popular neighborhoods like Shibuya or Roppongi, architectural facade lighting or neon signage fills the vertical space and “street lighting” is virtually non-existent. However, a variety of decorative streetlights festively illuminate the streets of Asakusa for a very fitting lighting environment. Pub signage and lanterns dispersed along the dark streets of Asakusa create an uncanny charm in this neighborhood. Roadway lux levels are a fairly dim 10-16 lx, but the red lanterns hanging from the eaves of establishments dig up affection for this old town.

2023.01.20-01.22　Yuichi Anzai+ Chuanyi Liu　 ■Kozushima Village Kozushima is located about 180 kilometers south of central Tokyo with a population of about 1,800. The terrain is complex, with almost no flat land. The village is located in the center of the island at the foot of Mt. Tenjo. The impetus for the starry sky protection activities on Kozushima came from a comment made during a student internship program by the Tourism Foundation in 2016, that the night sky was as beautiful as a planetarium. The starry sky, a common sight on the island, has become a tourism resource. An island-wide effort to protect the sky began. Specific efforts include replacing streetlights and security lights with fixtures with 0% upward luminous flux and 2,700K color temperature, holding explanatory meetings for residents and regular workshops with experts to gain their understanding and cooperation in light pollution and starry sky protection activities, training islanders as guides, and holding star gazing events to protect the night sky from light pollution and communicate the appeal of the starry sky both on and off the island. The island is also working to protect the night sky from light pollution and convey the charm of the starry sky to the public. The “Light Pollution Prevention Ordinance to Protect the Beautiful Starry Sky of Kozushima Village,” which specifies the responsibilities of residents and businesses to prevent light pollution, will be enacted in 2019, and rules are being developed to…

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…
