Hashima Island
About 5,259 people lived here in 1959, which made it the most densely populated place on earth. Mitsubishi closed the mine in January 1974 and the last residents were gone by April. In July 2021 the World Heritage Committee recorded its deep regret that Japan had not told the full history of the Koreans made to work here.
Field Guide Entry
The company island
Mitsubishi worked undersea coal from Hashima from 1887 and built upward on a rock barely big enough for the workforce. The apartment blocks that give the island its skyline went up from 1916 and are among the earliest large reinforced concrete buildings in Japan. The population reached about 5,259 in 1959. The mine closed in January 1974 and the island was empty by April of the same year.
The listing and what it left out
Hashima was inscribed by UNESCO in 2015 as part of the Sites of Japan's Meiji Industrial Revolution. Winning that listing required Japan to accept that the presentation would make clear that some of the sites used labor brought from the Korean peninsula.
In the official statements, Japanese representatives used hatarakasareta, were made to work, rather than kyosei rodo, forced labor. The interpretation center opened in Tokyo, about as far from the site as it is possible to put it. On July 22, 2021 the World Heritage Committee adopted a decision expressing deep regret that Japan had not carried out what it agreed to, and asked for the history to be presented properly.
Korean researchers, survivor groups, and Japanese memory-activist organizations continue to dispute how the island is presented. That argument is live and it is not a footnote to the ruins; it is the reason the ruins are internationally contested.
What is standing
Typhoons have been taking the island apart since the last ferry left. Floors have gone, stairwells have gone, and the seawall is repaired in sections to keep the tour route usable. Visitors see a short fixed walkway near the southern tip. Everything behind the barriers is coming down on its own schedule.
Visiting Information
Landing is possible only with one of the five operators licensed by Nagasaki city. Budget roughly 4,250 to 6,650 yen per adult, which is an operator fare of 3,600 to 6,000 yen plus the city's 650 yen landing fee. Premium plans with a guide and museum entry run 9,000 to 12,000 yen.
Whether a boat can land depends on wave height and wind, and it is called off often, in which case the trip usually continues as a cruise around the island. Refund terms differ by operator: Yamasa Shipping returns the landing fee in full and 10 percent of the boat fare when landing is not possible. Spring and autumn are the most comfortable, and summer has the best landing record.
The visit is a short fixed walkway near the southern tip, with the rest of the island closed because the concrete is failing. That route has been shortened and rerouted more than once, so what is reachable is not fixed year to year.
English-language guiding is limited and varies by operator and by day.
