Through the discussion of experts from various fields and the prophecies of a 100 prophets, we were able to piece together clues to the nightscape of this bustling city a half a century away. Talk Events ／Round Table Live Talk 2050／World Nightscape Talk We had a round-table discussion for seven consecutive days. Up to eight elite speakers will sit around a 2.4 m diameter round table and discuss under each theme.

On the last session, we had a lap-up talk to conclude all talk series . It is not a symposium with a stiff shoulder, but operates in a friendly salon atmosphere.

Let’s explore the city in teams of up to five! 2020.Oct.- Nov.　Tomoya Furukawa + Naoko Oguchi + Shinichi Sakaguchi + Shinichi Sakaguchi + Takashi Amemiya + Yuka Suzuki + Amane Kotani To prevent the spread of COVID-19, we held a “Small Group” night walk survey in seven locations —including Kansai—limiting each group to a maximum of five participants. It was our first walk in a year. With the pandemic, had the vibrancy of the city at night changed? Patio Juban – The warm glow of the bollard lighting harmonizing with the gradually turning leaves of the zelkova trees created a pleasantly inviting atmosphere Based on the results of the “Future Detective Night Walk Planning Salon” held at the end of August, we organized seven small-group night walk surveys from late October to mid-November, each with up to five participants. We selected seven areas—five in Tokyo, plus Nagoya and Osaka—and participants chose their preferred locations. It was our first night walk in a year, and we were reminded of the joy of seeing things firsthand and exchanging opinions on-site with fellow members. Each area had its own theme, allowing us to explore the unique characteristics of each neighborhood. ■Azabu-Juban – Motoazabu – Nishi-Azabu Azabu-Juban Odori – The warm orange lighting beautifully reflected off the stone pavement, creating a cozy and inviting ambiance Low-rise luxury residences – The illuminated grounds exuded an air of sophistication and elegance Azabu-Juban, a district blending tradition…

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…

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…

It is famous for its skyscrapers such as Taipei 101 and, more recently, for buildings designed by Japanese architects. Renovations of old buildings are also being actively undertaken. We investigated how the mixture of old and new influences the light and human activity in the cities of Taipei and Taichung. Taipei and Taichung The capital of Taiwan, “Taipei” is characterized by world-class skyscrapers such as Taipei 101 and streetscapes that retain historical architecture. In addition to new buildings, there are also many renovations of existing buildings, creating a city with a mixture of old and new architecture. Taichung has become the second largest city in Taiwan in terms of population in 2017 as a result of government-led urban development efforts in recent years to disperse the over concentration of the metropolis in Taipei.We investigated how Taichung, planned as a compact city, affects the city’s light and human activity, and how it differs from Taipei’s light. Taipei’s Urban Area Taipei’s urban area can be roughly divided into two areas. The west side of the city is the Old City,…
