Tatsunoshima Island

Tatsunoshima Island

辰の島

Nagasaki · Kyushu

An uninhabited islet off northern Iki ringed by white sea-cliffs and a brilliant turquoise cove, circled by cruise boats from Katsumoto. The cove is open for swimming in summer, when the boat service runs most frequently.

Why it's hidden

A castaway-blue islet only reachable by local boat from an already off-grid island.
