Gunkanjima Island: The Rise and Fall of Japan’s Ghost Island

Just off the coast of Nagasaki lies Gunkanjima, or Hashima Island, a tiny speck of land with a history as haunting as its present-day ruins. Known as the “Battleship Island” for its resemblance to a warship, this fortress-like island was once the most densely populated place on Earth. Today, it stands as a ghostly reminder of Japan’s industrial past and the lives that were lived—and lost—on its shores.

Origins: A Coal Mining Powerhouse

Early Development

  • Mitsubishi Corporation: In the early 1900s, Mitsubishi began developing Gunkanjima after discovering rich undersea coal deposits beneath the island.
  • Industrial Expansion: For nearly a century, the coal extracted from Gunkanjima fueled Japan’s rapid industrial growth, making it a key asset in the nation’s modernization.

Peak Productivity

  • By 1941, the mine was producing 400,000 tonnes of coal per year, with tunnels stretching deep under the seabed.
  • The workforce included forced laborers from Korea, a grim reminder of the darker aspects of Japan’s wartime history.

The “Island Without Green”

Urban Transformation

  • To accommodate the miners, Mitsubishi constructed high-rise apartment complexes, creating a densely packed, vertical city on the less-than-one-square-kilometer island.
  • Infrastructure: The island boasted schools, restaurants, gaming houses, and even a cinema, all encircled by a protective seawall.

Population Boom

  • By the mid-1950s, Gunkanjima housed nearly 6,000 people, giving it the highest population density ever recorded.
  • Life on the island was harsh, with limited space, oppressive working conditions, and no natural greenery—earning it the nickname “Midori nashi Shima” (The Island Without Green).

The Decline and Abandonment

The End of Coal

  • As Japan transitioned to petroleum in the 1960s, demand for coal plummeted. By 1974, the mine was no longer viable, and Mitsubishi closed it.
  • In a matter of weeks, the entire population evacuated, leaving the island frozen in time.

Nature’s Return

  • Over the decades, the island’s buildings crumbled, and vegetation began to reclaim the barren courtyards and streets.
  • The once-bustling city became eerily silent, with broken glass, peeling walls, and rusted machinery telling the story of its abandonment.

Gunkanjima Today: A Haunting Ghost Town

Frozen in Time

  • The island remains almost exactly as it was when it was abandoned, a decaying monument to industrial ambition and urban density.
  • The ruins, including the collapsing apartment blocks and seawalls, are a stark juxtaposition of human achievement and nature’s resilience.

Tourism and Recognition

  • In 2009, limited tourism was allowed, with guided boat tours offering visitors a glimpse of the island’s eerie beauty.
  • UNESCO World Heritage Site: In 2015, Gunkanjima was recognized as part of Japan’s “Sites of Japan’s Meiji Industrial Revolution.”

Cultural Legacy

  • The island has captured imaginations worldwide, appearing in movies like James Bond’s Skyfall and documentaries exploring its unique history.

A Complex Legacy

Industrial Achievement

Gunkanjima symbolizes Japan’s industrial ingenuity and rapid modernization, showcasing the extraordinary lengths taken to extract resources from a challenging environment.

Human Cost

The forced labor and harsh conditions endured by many workers, particularly Korean laborers during World War II, highlight the ethical complexities of its history.
