Washery Interior

A square-faced clock hangs on the far wall of the bathhouse at Ikeshima Coal Mine, centred above a bank of windows whose daylight throws the near troughs into silhouette. Long concrete troughs run in a line across the tiled floor. A rusted trough studded with spigots lines the right wall. A central concrete pillar carries the overhead pipework through the room, and a dark ventilation duct crosses the ceiling to the right. Two tall metal cabinets stand against the far wall between the window sections. The clock face still reads a time. This room was the surface end of a shift. Miners coming up from workings that reached nearly 650 m below the seabed crossed through here before heading back into the island community above. At the mine's 1970 peak, that community numbered 7,770 people living on an island roughly 1 km² and about 4 km around, housed in reinforced-concrete apartment blocks because the island had no room to spread. Ikeshima Coal Mine was operated by Matsushima Coal Mining Co., Ltd., a subsidiary tracing its lineage to Mitsui Mining's 1913 purchase of the Matsushima concession. Commercial output at Ikeshima began in 1959, making it the last new coal mine to open in Japan. The undersea field produced weakly-caking coking-blend coal of about 7,500 kcal/kg, valued for its low sulphur content. Peak output exceeded 1.5 million tonnes in 1985. The mine closed on 29 November 2001, the last large-scale underground colliery in Japan, after 42 years of production. What the 2026 photograph records is the bathhouse as it stands now: clock, troughs, pipework, cabinets, the geometry of a room built around a daily routine that ended more than two decades ago.
