A tiny island housing Japan's only decommissioned coal mine that visitors can walk around in has struck the tourism lode amid rising public interest in industrial heritage.
The island of Ikeshima in the city of Nagasaki is about 4 km in circumference. The mine there, which opened in 1959, was one of the last two in the nation before it closed in 2001.
At its peak, during Japan's postwar growth spurt, the island was home to some 8,000 men, women and children living in vast apartment complexes.
