Defining Feature
A compact island settlement built around an underwater coal mine
Status
Preserved - Deserted since 1974; Hashima Coal Mine is a protected but deteriorating World Heritage component
Overview
Hashima became a densely built coal-mining community on a small island off Nagasaki after 1890.
Concrete apartment blocks, schools, shops and industrial structures covered much of its narrow surface. More than 5,000 people lived there at its recorded peak.
The mine closed in 1974, and the population departed. The deserted island is now protected, although its remaining buildings continue to deteriorate.
Why It Mattered
Hashima compressed work, family life and heavy industry into an extraordinary sliver of land. Its ruins embody both Japan’s rapid industrial growth and the fragility of communities built around a single resource.
Underwater Coal Mine
- Coal was extracted from an underwater mine serving Japan’s industrial economy.
Settlement Scale
- The island measures about 160 metres east to west and 480 metres north to south.
- Its recorded peak population exceeded 5,000.
Protection and Access
- Access is controlled, while deterioration presents continuing conservation challenges.
- Hashima entered the World Heritage List in 2015 as part of a 23-component industrial property.

Hashima's dense buildings occupy almost the whole island, illustrating how a mining community compressed work and domestic life into a tightly bounded offshore settlement.
