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…

In the middle of Tokyo is the Imperial Palace, a haven for runners and tourists, alike. The lighting in the palace outer garden and nearby Wadakura Fountain Park has been renewed and replaced with environmentally conscious LED fixtures. We surveyed the unique pocket of darkness that surrounds the Imperial Palace along with lighting environment of nearby parks and roads. Imperial Palace Outer Garden. The fancy pole lights in the outer garden are originally gas lamps, but the light source has been changed to high-pressure sodium lamps and now upgraded to LEDs. The average lux level is only 1-2lux along the paths lined with these LED fixtures, but inside the fixtures are 6, 26watt LED modules all pointed in different directions. This application helps to spread the light around without making a too bright, but comfortably dim atmosphere. Daikancho Street Daikancho Street runs along the north side of the palace grounds, is a much narrower street and pedestrian sidewalk compared with the rest of the facilities surrounding the palace. Along the tidy, hedged sidewalk, streetlights are placed at 3-meter intervals. Mostly for crime prevention, the lights are very bright and glaring. Ohtemachi Entrance The Ohtemachi Entrance area leads to an inner palace garden and is surrounded by a main arterial road on the outside, for a very open and accessible area. Most lighting is road lighting, mounted on 10-meter tall poles arranged down the middle of the street, but plenty bright…

Shimokitazawa is a neighborhood of small shopping streets and alleyways, projecting a strange, but comfortable atmosphere, as people crowd the backstreets until late in the night. However, plans to replace this quaint neighborhood with arterial roads and high-rises are underway. The detectives took what maybe a last chance to survey this area before it is “defaced.” The top half and rooftops of most buildings do not have any luminous signage. As a result, a bird’s eye view of this neighborhood is actually fairly dark. The station front plaza is filled with people listening to music from sidewalk acts or looking at street art. The crowds of people naturally overflow into a nearby street. If an arterial road is planned for this area, this atmosphere will be lost forever. Two streets back-to-back, but built to two different scales and with two different demeanors. On the left is Shimokitazawa`s main south entrance shopping street. With many interior decor shops, the lighting is bright and color temperature is high. One street inside and the atmosphere and lighting are more relaxed. Low color temperature, incandescent lamps from restaurants, cafes, and bars are the main source of light.

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…

2024.9.9 Yonglin Ke + Kunzhi Jinag + Linxi Chen The brightness (luminance) of signage lighting is key to shape the overall lighting of a city. This survey conducted in Akihabara, a globally famous district, focused on the renowned Akihabara Electric Town (Chuo-dori), analyzing the evolution of the city’s lighting composition by comparing it to the survey from 19 years ago. ■Akihabara Electric TownAkihabara is the heart of electronics in Tokyo and a globally famous hub for otaku culture. While it is bustling with tourists daily, the colors of the signs, filled with anime and game culture, are much more diverse compared to upscale commercial areas like Ginza or other shopping districts. In 2020, Chiyoda Ward released guidelines for outdoor advertising and urban development, leading to changes in Akihabara’s streetscape. This survey investigates the current night view of Akihabara Electric Town, comparing it to a survey conducted 19 years ago. (Kunzhi Jiang) ■What kind of lights shape Akihabara?The main lighting elements in Akihabara’s key districts include streetlights, signage lighting, building façade lighting, and lighting from store entrances and spillover light.Compared to the picture from 19 years ago, the most noticeable green and red lights from EDION were not illuminated due to the store’s closure. The ONODEN sign is now an LED screen, and the surrounding lighting has a more subdued feel. Previously, the area behind the bridge was completely dark, but now, with the bright lighting from a drugstore’s interior and…
