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…

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…

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.

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…

From up above Tokyo looks like an overturn jewelry box, the night streets glitter with lights and it a fairly beautiful sight. Once back on ground, the glitter has turned harsh. It is an economically advanced nightscape, an efficient nightscape with needless light and light pollution. An aerial view of Tokyo at night. The dark area in the center of Tokyo, the Emperor`s Palace, is surrounded by clusters of lights that resemble precious stones. From this view it is unclear where Tokyo begins or ends. The Tokyo nightscape is illuminated in bright white light. Mercury lamps and florescent lights in the background of Tokyo Tower control the nightscape of this city. Old-fashioned houseboats gather in the foreground of the Odaiba District and the Rainbow Bridge.
