Gunkanjima, otherwise known as Hashima or Battleship Island, is a historic island 20km offshore from Nagasaki. The entire Island once served as a coal mine and staff housing, until it was shut in 1974. At its height, the 480-meter-long, 150-meter-wide island housed 5000 staff and families of the coal mine, and once held the record for the highest population density. The eerie abandoned concrete structures mine now act as a tourist attraction, among the top sites in Nagasaki.
To house the sheer number of residents on the small island, every bit of land was utilised. The island’s formal name is Hashima. Hashima is more commonly known as “Gunkanjima” or “Battleship Island” in Japanese due to the physical resemblance of the island to a massive battleship, which was built up to accommodate a large population in a small area.

Coal was first discovered in 1810, but the industrialised mining process commenced towards the late 1800s. The island was then purchased by the Mitsubishi Corporation, which led to an increase in production on the island. As production increased, so did the island’s needs. Roughly about half the island’s population was coal miners, while the others worked in schools, hospitals, restaurants, and other facilities to help sustain the coal mining operation.
Tourism on the island commenced in 2009 when a new boat dock made it safe and easy to access the island. Tours are conducted throughout the day, spending about 45 minutes on the island, and 50 minutes on the water in each direction, providing great views of Nagasaki city. Tours are primarily operated in Japanese.
