About the desolated island

A Brief History of Gunkanjima

Gunkanjima’s history dates back to 1887 when coal was first discovered on the island.

Mitsubishi bought the island in 1890, developing it into a thriving coal mining community. At its peak in the 1950s, Gunkanjima was home to over 5,000 residents, making it one of the most densely populated places on Earth.

“Gunkanjima” (or “Battleship Island” because of its shape) is an abandoned island built by Mitsubishi corporation. Its sole purpose was to house 5000 residents there to work in its coal mine for 100 years.

However, as Japan shifted to petroleum as its primary energy source, coal mines began to shut down, leading to the island’s abandonment in 1974.

Today, Gunkanjima stands as a stark reminder of Japan’s rapid industrialization and its subsequent decline.
