Tsutashima

Tsutashima is an uninhabited island off the coast of the Saganoseki Peninsula in Ōita. It features striking rock formations carved by waves and coastal winds over many years.

The island gained protected status in 1974 when it became part of a large marine conservation area. This designation ensured long-term preservation of its natural landscape.

Local maritime workers maintain a collection of navigation stories about the waters surrounding Tsutashima, passing their knowledge through generations.

Boats from nearby coastal areas are the only way to reach the island and must be arranged ahead of time. Checking weather conditions is essential since crossings depend on calm seas and clear skies.

The island serves as a vital refuge for seabirds that breed and nest without human interference. The absence of settlement has preserved a natural habitat important for numerous bird species.
