Tokyo Survey: Tsukuda / Tsukishima 2019.11.18　　Kyoko Takubo+Yuichi Anzai+Namiko Watanabe An overview of Tsukishima. In contrast to the bright large city buildings, the small alleys and storefronts don’t leak much light Tsukuda is an fisherman island made in Edo-period. Tsukishima was landfilled in Meiji era and now there are still many row houses and small alleys. While the port area of Tokyo is going through mass redevelopment, we investigated the lighting environment of this area filled with intermingling old town houses and large city buildings. Tsukuda Tsukuda 1Chome Mainstreet. Children playing outside the old candy store Tsukuda 1 Chome Mainstreet is mainly lit with mercury lamps Tsukuda Machikado Museum. Its lit with LED3000K with about 134lx. Our investigation started by taking an overview photo from a tall building from the other side of the river. With the hustle and bustle bright lights from the Central area’s cityscape, there was one part that was dark- that is our target of this investigation, Tsukuda・Tsukishima. The dark patch from this area is even more pronounced as it is surrounded by the bright city lights all around.   As we get back on the ground, we headed towards Tsukuda 1 chome (Old Tsukuda Island) Mainstreet. On our way we saw the mercury lamp streetlights (4500K) emitting some green tinted white light. The average brightness was around 11lx. In the day you could still see a nostalgic scene with children playing outside the old candy store…

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…

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…

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…

In the heart of Tokyo, Nihonbashi River lies hidden under a system of highway overpasses and the Sumida River is wide and commanding and it cuts through the city. With a variety of bridges, both rivers assert their own unique presence in the Tokyo cityscape. On our own river tour, we encountered the particular water and lightscapes surrounding the bridges and shores of each river. The newly built Nihonbashi Mitsui Tower next to the famous Nihonbashi Bridge. This is the first skyscraper in the Nihonbashi area and as the sun sets, the facade detail is elegantly illuminated. At the historical Nihonbashi District, a variety of lighting methods are on parade, but the highway overpasses keep most of the river hidden from view. Rumors of reconstructing the highway system underground would help revive the scenery along the Nihonbashi River. The main structure of the Chuo-Ohbashi Bridge is beautifully illuminated. The many bridges along the Sumida River compete with each other for top beauty marks, as each is illuminated in a multitude of colors.
