# Hashima Island (Gunkanjima)

> A UNESCO World Heritage Site as part of the Sites of Japan's Meiji Industrial Revolution, Hashima Island (Gunkanjima or Battleship Island) is an abandoned coal mining island off the coast of Nagasaki. Once the most densely populated place on earth, the island's crumbling concrete apartment blocks and industrial ruins create a haunting post-apocalyptic landscape accessible only by boat tour.

Hashima, universally known as Gunkanjima or 'Battleship Island' for its warship-like silhouette, is one of the most unusual places in Japan: a tiny abandoned coal-mining island in the sea off Nagasaki. Mitsubishi began undersea coal mining here in the 1880s, and to house the workforce the island was packed with concrete apartment blocks, including Japan's first large reinforced-concrete building (1916). At its peak in 1959 some 5,259 people lived on the 6.3-hectare rock, making it the most densely populated place on earth, with schools, shops, a cinema, and even rooftop gardens. When Japan switched from coal to oil the mine closed in 1974 and the island was abandoned almost overnight; today its crumbling towers and empty stairwells form a haunting, post-apocalyptic ruin. Inscribed in 2015 as part of the 'Sites of Japan's Meiji Industrial Revolution,' it carries a difficult history too: wartime Korean and Chinese labourers were among those who worked the mine. You can only visit by licensed boat tour from Nagasaki Port: a fixed walking course with three viewing platforms (you cannot enter the buildings), with landings cancelled in rough seas.

## FAQ

### How do I book a Gunkanjima boat tour?

Five licensed operators run tours from Nagasaki Port: Gunkanjima Concierge, Yamasa-Kaiun, Gunkanjima Cruise, Takashima Kaijo, and Seaman Shokai. Book online 1 to 2 weeks ahead (more in summer/Golden Week). Tours cost ¥4,000 to 5,000 including the ¥310 island landing fee. The whole excursion is about 3 hours; landing time on the island is 40 to 60 minutes.

### Will I actually land on the island?

Landing is weather-dependent; about 60 to 70% of tours actually land. Operators sail regardless but only dock if waves are under 0.5 m and wind is calm enough. If landing is cancelled, you still circumnavigate the island and most operators offer partial refunds (around ¥1,000) or rebooking. Even without landing, the views from sea are striking. Visit on calm spring or autumn mornings for the best landing odds.

### What can I see on the island?

A fixed walking course with three viewing platforms; you cannot enter the buildings for safety. Highlights include Japan's first reinforced-concrete apartment block (1916), the abandoned coal-shaft entrance, and the towering schoolhouse silhouette. Tours include narrated history covering the island's peak population of 5,259 in 1959 (highest density on earth) and its 1974 closure. The Nagasaki Gunkanjima Museum near the port adds context (¥1,800).

### Is Gunkanjima suitable for kids or those with mobility issues?

The walking course is short (~500 m) and flat, but the boat ride can be rough, so operators recommend motion-sickness medication. Strollers and wheelchairs are not permitted on the landing pier. Children must be at least preschool age on most tours, and one operator (Yamasa-Kaiun) requires age 6+. Pregnant visitors and those with heart conditions should reconsider, especially in choppy weather.
