Hashima Island

Mystery rating

Hashima, known as Battleship Island, is a small concrete island off Nagasaki. Thousands of coal miners and their families lived here in some of Japan's first big concrete apartment blocks. The mine closed in 1974 and everyone left within weeks. The buildings have been falling apart ever since.

Why it's famous

Hashima, nicknamed Gunkanjima or "Battleship Island" for its shape, is famous first for numbers: over 5,000 residents crammed into 6.3 hectares, a density of more than 83,000 people per square kilometre. Mitsubishi built Japan's first large reinforced-concrete apartment block here in 1916, specifically to survive typhoons that wooden housing couldn't withstand. When the coal mine closed in January 1974, the last resident left within three months, leaving behind a complete but empty town. The island's history includes a serious and still-debated chapter: during the 1930s and the Pacific War, Korean and Chinese labourers were forced to work the mines under brutal conditions, and many died. This history shaped its 2015 UNESCO listing as part of Japan's Meiji industrial heritage, which came with an acknowledgement of forced labour. Its stark silhouette has since made it a fixture in films, including the villain's lair in Skyfall.

History

Coal was discovered deep beneath the seabed here in 1810. Later, in 1890, the Mitsubishi company bought the island. They started digging mine shafts that eventually went down more than a kilometer (over half a mile) below the ocean floor. To house all the miners, Mitsubishi expanded the island by reclaiming land, built a strong sea wall around it, and started constructing buildings upward. Block 30, finished in 1916, was Japan's very first large, reinforced-concrete high-rise building. It was built this way because regular wooden buildings couldn't survive the powerful typhoons. By 1959, the island was home to 5,259 people. It had everything: shops, a school, a hospital, a cinema, bars, a swimming pool, a Shinto shrine (a place for traditional Japanese worship), and even vegetable gardens on the rooftops. All these different areas were connected by stairways so steep and dark that people called them the "Stairway to Hell." However, the island's history also includes a darker side involving forced labor. During the 1930s and the Pacific War, Korean and Chinese workers were forced to labor in the mines under terrible conditions, and many of them died. This period remains a sensitive diplomatic issue. It also influenced how the island was recognized by UNESCO in 2015 as part of Japan's Meiji industrial heritage, with an acknowledgement of the forced labor history. When Japan started using oil more than coal, the mine closed down in January 1974. The very last person left the island that April.

The full story

You can't just wander freely on Hashima Island. Visiting is only allowed with official tours from Nagasaki. You'll stick to a short, strong walkway on the island's southern tip, as the rest of the island is falling apart, with concrete crumbling off the buildings every year. But this small restriction is absolutely worth it. From that walkway, you'll look straight up into the towering canyon of Block 65, and the sheer size of it will hit you much harder than any photo ever could. Boats leave from Nagasaki Port, and the trip takes about 50 minutes. Before landing, they'll circle the island so you can see its distinctive shape, which looks like a battleship – that's where its nickname comes from. Keep in mind that landings are canceled if the waves are higher than 0.5 meters. This means about one out of three trips won't actually land. It's a good idea to plan an extra day in Nagasaki and book the morning departure; those often have better luck. Either before or after your island trip, make sure to visit the Gunkanjima Digital Museum in Nagasaki. Here, using projection mapping and virtual reality, you can explore the apartments, hallways, and mine shafts that you can't enter on the actual island. If you combine these two experiences, the island becomes much more than just a scenic ruin. Nagasaki itself is worth at least two days. You can explore the Atomic Bomb Museum and Peace Park, the old Dutch trading post at Dejima, the beautiful Glover Garden, the Ōura Church, and enjoy the night view from Mount Inasa, which is considered one of the best in the world. Don't forget to try champon noodles and castella cake, both of which originated here. If you're a photographer, bring a fast telephoto lens. You'll be shooting from a fixed spot, often in flat sea light. The best time to go is in late autumn, after typhoon season has ended, when the air is clear and the sea is at its calmest.

Legends & sightings

Gunkanjima has become more of a modern legend than just a physical place. It provided the look for the abandoned island hideout in the James Bond movie 'Skyfall,' appeared in the live-action films of 'Attack on Titan,' and pops up constantly in video games and photography books as the perfect symbol of a ruined future. Yet, former residents tell a very different story from this popular "ruin porn" image. They remember Hashima as a lively, warm, and friendly place, a town where everyone knew each other and children played on rooftops high above the Pacific Ocean. Many return for memorial visits and speak of sadness, not horror, when they recall their home. The island also has a truly dark history. Survivors of the forced labor described the undersea mine shafts as a place where men were often carried out unconscious from the extreme heat. The island's Korean name, "Hell Island," comes from that grim period. Local fishermen have long avoided the waters off the north side of the island after dark. So, whatever you might think about whispers in the stairwells, the island's actual haunting—the memory of its painful past—is well-documented, still debated, and unresolved.

Can you visit?

Only on an official tour. Landing tours run from Nagasaki and are the only legal way to set foot on the island. Landing depends on sea conditions and is cancelled often. Visitors stay on a short fenced walkway, because the buildings are unsafe. You cannot explore the ruins.

How to get there

1. Fly into Nagasaki (NGS) or take the train to Nagasaki station. 2. Book a landing cruise with a licensed operator in Nagasaki port. 3. The boat trip takes roughly 40 to 50 minutes each way. 4. Tours usually last two to three hours in total. Book online before you arrive, especially in high season.

Before you go

Book ahead and pick a tour early in your stay, so you can rebook if the sea cancels it. Operators may refuse boarding in rough weather. That is for your safety. Bring sun protection. The walkway is exposed. Tours are usually in Japanese, so check whether English support is offered. People with mobility problems may not be able to land, as there are steps and a moving boat.

What to expect

You sail out, circle the island for photographs, then walk a short marked route past the ruins with a guide. You see the crumbling apartment blocks, the sea wall and the old mine shaft entrance from a distance. It is a couple of hours, mostly on the water, and the scale of the decay is the thing you remember.
