History
Oshaku-jima has long been known to those who live by the sea as an island off the coast of Tobishima. The surrounding Sea of Japan changes greatly with the seasons and weather, while the island's silhouette remains a constant presence on the water. Detailed accounts of its history and use are limited, so please confirm with official sources.
Access
The island lies in the Sea of Japan about 2 km west of Tobishima, Sakata City, Yamagata Prefecture, near 39.19 degrees north and 139.52 degrees east. Tobishima itself is reached by regular ferry from Sakata Port. Because landing on or cruising around Oshaku-jima may be subject to conditions, it is best to check local boat operations and official information.
Best season
The most accessible time is from spring through autumn, when the sea is calmer and boats run more readily. The winter Sea of Japan can grow rough, so checking the weather and sea conditions before planning is advisable.
