, often called Gunkanjima ("Battleship Island") due to its fortress-like silhouette, is one of Japan’s most iconic abandoned sites. Located about 15 kilometers from Nagasaki, it is known for its dramatic industrial history, unique architecture, and as a symbol of both Japan’s rapid modernization and its darker wartime legacy35.
Hashima was originally a barren rock in the sea, considered useless until the late 19th century.
In 1887, the first undersea coal mine was established, marking the start of the island’s transformation during Japan’s industrial revolution35.
The Nabeshima Clan initially controlled the neighboring Takashima coal mine and allowed the Fukahori family to develop Hashima. After some failed attempts, the Fukahori family succeeded in establishing a shaft mine and sold the island to Mitsubishi Corporation in 1890 for 100,000 yen5.
Mitsubishi rapidly expanded mining operations, constructing sea walls and using mine slag to reclaim land, creating space for industrial facilities and multi-story concrete apartment blocks. By 1907, the island was encircled by high sea walls, giving it the appearance of a battleship5.
At its height in 1959, Hashima housed over 5,200 residents on just 6.3 hectares (16 acres), making it one of the most densely populated places on earth at the time3.
The island featured schools, shops, a hospital, and entertainment facilities, all built to serve the mining community living in tightly packed concrete buildings35.
During World War II, as Japan’s demand for coal soared, labor shortages led to the forced recruitment of Korean and Chinese workers, many of whom endured harsh conditions and starvation. This period remains a controversial and painful part of the island’s history35.
The coal mine’s annual production peaked at 410,000 tons in 1941, but this came at great human cost5.
As Japan shifted from coal to petroleum in the 1960s and 1970s, coal demand plummeted. Mitsubishi closed the mine in 1974, and the island was abandoned almost overnight35.
For decades, Hashima stood as a ghost island, its concrete structures left to the elements.
Interest in Hashima revived in the 2000s, partly due to its haunting ruins and its appearance in films and documentaries.
In 2009, the island was reopened to tourists, and some restoration work was done to ensure safety3.
In 2015, Hashima’s coal mine was designated a UNESCO World Heritage Site as part of the "Sites of Japan’s Meiji Industrial Revolution"3. However, the listing has been controversial due to unresolved issues about how the history of forced labor is presented3.
: A symbol of Japan’s rapid industrialization and urban engineering, showcasing early 20th-century concrete architecture.
