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…

Rich in local history and cultural facilities, Ueno Park covers a large area in the middle of Tokyo. Even though located in an urban setting, we anticipated a lighting environment completely different than the lights of downtown. Between the trees and darkness of the park there are patches of Tokyo`s bright night sky, but the hushed silence is isolated from the city`s hustle and bustle. Ueno Park`s quiet presence gently sleeps next to Tokyo`s vibrant downtown. Approaching Ueno Park from the JR train station.　　The large overhang of the Tokyo Bunka Kaikan is brightly illuminated in contrast to the surrounding darkness of the park. A view o f northern Tokyo over the Shinobazu Pond from an elevated Ueno terrace. The bright lights of a vibrant downtown are seen in the distance beyond the dark trees of the park. However, through the darkness a bright, orange, sodium lamp illuminates the Benten Shrine near the pond. Looking towards the water fountain plaza from the Tokyo National Museum. A slightly bright night sky, characteristic of most metropolitan areas, opens over head with a dark belt of trees and tiny dots of light below. Young couples seeking a quiet spot away from the lights, snuggle up together on near benches.

Shiodome Sio-Site was a joint public and private sector redevelopment project completed in 2006. In nearby Shinbashi, eateries and bars built under and into the brick structure of the elevated railway tracks during the Meiji era have become a famous cityscape of this area. We set out to discover what kind of lighting environment exists in this conflicting neighborhood of Tokyo. Red lanterns, single light bulbs hanging under the eaves, colorful luminous signage…All the lighting is warm and inviting. The lighting environment along the streets of Shinbashi is wide and varied, but somehow closes the distance between strangers. Lighting for an elevated pedestrian deck connecting high-rise buildings in the area. The warm colored lighting creates a comfortable atmosphere for a nighttime stroll. The Shiodome high-rise buildings are not showy, and along with the interior office lighting, only a few have facade lighting on the building crowns.

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…

2022.11.4-5 Sachiko Segawa Surprisingly, this survey of the Sawara district marks the first time the Lighting Detectives have conducted an investigation within Chiba Prefecture. The team focused on an area designated both as an Important Preservation District for Groups of Traditional Buildings and as a Landscape Formation District. Here, the townscape of merchant houses, which flourished from the Edo period thanks to river transport on the Tone River, still remains. Located about 70 km from Tokyo Station and slightly inland from the Tone River, the Sawara district of Katori City once thrived as a merchant town, to the point it was said to rival Edo itself. However, the town declined during Japan’s period of rapid economic growth. Following a townscape survey in 1974, the value of its historic scenery was reappraised. Today, leveraging its convenient location—just two hours from Tokyo and one hour by train from Narita Airport—the area is being redeveloped as a tourist destination. For this survey, the team limited their scope to the townscape along the Ono River and conducted a nightscape survey. ■Uniquely Designed Lighting Fixtures From JR Narita Line Sawara Station, as we walked toward the Ono River, we were greeted by a bollard topped with a monkey. “Why a monkey…?” we wondered, but as we continued upstream along the river, we encountered bollards adorned with all sorts of figures: rabbits, carp, children, frogs, Ebisu, and more—each one different, with no two alike. These uniquely…
