Overview
Mishima is an inhabited island in the Sea of Japan belonging to the city of Hagi, Yamaguchi Prefecture. Lying about 44 km offshore in the open sea, it covers roughly 7.73 square kilometers and measures about 2.5 km across and 4.6 km from north to south, home to around a thousand residents. A volcanic island formed of basalt, it is kept milder than its latitude would suggest by the warm Tsushima Current. Refreshingly undeveloped, Mishima suits travelers seeking the quiet of a remote island rather than crowds.

History
Positioned on the sea routes of the Sea of Japan and near the approaches to the continent, Mishima has long carried the character of a border island. Its origins as a basalt volcanic island shaped both its terrain and the way people live here. Fishing became the mainstay of island life, and a distinctive maritime culture has been handed down over generations. For details on specific historic sites and legends, it is best to check local guides or official information.
Access
The island sits offshore from Hagi in the Sea of Japan, at roughly 34.78 degrees north and 131.14 degrees east, about 44 km from the mainland. Access is by scheduled ferry from Hagi. Because sailings can be affected by weather and sea conditions, confirm timetables and any cancellations through official sources in advance. Transport on the island is also limited, so plan your visit accordingly.
Best season
Warmed year-round by the Tsushima Current, Mishima offers something in every season. Spring through autumn, when seas are calmer and ferries run more reliably, is the easiest time to visit, and on clear days the open-sea views are superb. Winter brings rougher waters and more frequent cancellations, so check sea conditions before crossing.
