Date of Issue: 30 October, 2023-Activity 1 / City Night Survey : Iwakuni ＆Miyajima, Japan（2023.08.02-04） City Night Survey : Iwakuni ＆Miyajima, Japan 2023.08.02 – 2023.08.04　Yumi Honda＋Sachiko Segawa The theme of this survey is “lighting on boats since ancient times”. Cormorant fishing on the Nishiki River in Iwakuni has been practiced for about 400 years. The Kangensai Festival at Miyajima Island has been held since the Heian period (794-1192). We investigated the relationship between water, light, and people in these two different areas. ■Iwakuni　The Light of Cormorant Fishing, an Ancient Fishing MethodCormorant fishing has been practiced on the Nishiki River in Iwakuni City, Yamaguchi Prefecture, for about 400 years. The cormorant fishing is still enjoyed today by taking a pleasure boat ride from the foot of Kintai-kyo Bridge, one of the three most famous bridges in Japan. The day we visited was a weekday in mid-summer, and the daytime crowds were sparse, but in the evening, people began to gather along from somewhere the riverbank and board the cormorant fishing boats. In western Japan in summer, it is still light even at 18:00. Looking at the sightseeing boats from the bridge, I could see people enjoying a party on the boats with lanterns hanging down. As it gradually got darker and the lights of Kintai-kyo Bridge and lanterns along the river were lit up, we slowly waited for the cormorant fishing time to start. By the time the pleasure boat landed…

Tianjin is situated 150km east of Beijing and easily reached in a 30-minute high-speed train ride. Historically, foreign influence including the UK and Germany has shaped the western-style architecture and streetscape that this city is famed. Tianjin also poses the largest harbor in Northern China, a gateway for this economical and technical development zone. Upon exiting the main station, a panoramic view of the city awaits. The western architecture, remnants from the foreign settlements era, is illuminated in low-color temperature light and stands in contrast to the newly constructed skyscrapers. A historical western architectural structure is now used as a banking facility. At night, orange-colored fluorescent and high-pressure sodium lamps softly illuminate the facade. Downtown is also bustling with construction. During the day the area is swarming with shoppers and construction site workers. At night, mega size digital media, neon signage, and colorful lanterns are everywhere, with even more foreseeable in the future as the construction boom continues.

2011.08.09 Lighting Detectives Office Lantern Making Workshop, leaning process of design As a summer event for elementary school student, we had a children workshop titled “enjoy light of candle” 12 children joined this workshop and learned design process, and each of them designed their own lantern and chose and build one.

Date of Issue: March 28, 2023・Activity 1/ City Night Survey : Hitoyoshi, Kumamoto（2022.11.10-12） City Night Survey : Hitoyoshi, Kumamoto 2022.11.10-12　Mari Kubota + Noriko Higashi In July 2020, Hitoyoshi City in Kumamoto Prefecture was devastated by catastrophic flooding caused by heavy rainfall. Since the disaster, the city has made steady efforts toward recovery— efforts in which lighting has played a significant role. To understand how lighting has contributed to the city’s revitalization, we conducted interviews with local stakeholders, including hot spring inn owners and city officials, and followed up with an on-site investigation of the actual lighting projects. From July 3 to 4, 2020, torrential rains caused the Kuma River to overflow, resulting in catastrophic flooding in Hitoyoshi City, Kumamoto Prefecture. Known for its scenic beauty, hot springs, and hospitality centered around local shochu, this tourism-driven city suffered devastating damage—not only from the flooding but also from the impact of the COVID-19 pandemic. In response to the disaster, a local inn owner launched the Hitoyoshi Hikari no Fukkō Project (Hitoyoshi Light Recovery Project), using light as a tool for recovery. In 2021, Hitoyoshi was selected as a model city for Japan’s Cabinet Office-led Super City (SC) initiative, proposing a future-oriented recovery plan. This plan placed lighting as a key component, aiming to promote both disaster resilience and tourism attraction through thoughtful illumination. This survey included interviews with stakeholders such as hot spring inn owners, city officials, and lighting designers involved in…
