2024.11.21-11.22 Shunichi Ikeda + Yuta Shibata Yokkaichi has developed as an industrial city. The striking contrast between its dazzling factory nightscape and the increasingly organized city center stands out. We conducted a survey of the urban lighting where industry and daily life coexist. ■About Yokkaichi Yokkaichi has a long history, having developed as a port town facing Ise Bay. During the Edo period, it prospered as a post station along the Tokaido route. The city’s name originates from the markets that were held on days ending in “4.”After World War II, Yokkaichi grew as an industrial city with the construction of a petrochemical complex during Japan’s period of rapid economic growth. However, air pollutants emitted from the complex caused a serious pollution-related illness known as Yokkaichi asthma.Today, the city has regained a comfortable living environment. Residential areas, shopping streets, and everyday life now extend right alongside the industrial zones. ■3D Factory Nightscape Yokkaichi, with its history of industrial development, began drawing attention during the early 2000s factory nightscape boom. The expansive factory nightscape of the Yokkaichi petrochemical complex, which stretches about 10 kilometers north to south, is counted among Japan’s five greatest factory nightscapes. What makes it especially unique is that the nightscape can be viewed from the sky, land, and sea—earning it the nickname “3D Nightscape.” Particularly photogenic views of the factory nightscape have gained significant popularity. From the perspective of the Lighting Detectives, we conducted a survey of…

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 for a break, the sun had completely set and Iwakuni-jo Castle at the top of the mountain was lit up. Finally, it…
