Oshima

Oshima is a volcanic island in the Tokyo Islands where Mount Mihara, an active volcano rising 758 meters from the center, shapes the landscape with black sand beaches and lava formations. The terrain shifts between dark volcanic coasts and vegetated slopes, creating visual contrasts throughout the island.

The island formed through volcanic activity that continues to shape its landscape and character. In the 1930s, authorities built protective barriers around Mount Mihara's crater in response to a difficult period in the island's past.

The winter camellia festival draws people to see thousands of blooming flowers across the island, reflecting how deeply these plants are woven into daily life and local crafts.

The island is accessible via high-speed ferry from Tokyo's Takeshiba Terminal with a journey of about two hours, or by a shorter flight from Chofu Airport. Both options connect easily to the main area where most services and trails begin.

The Ura-Sabaku region near Mount Mihara features a black sand desert of volcanic material that looks almost otherworldly against the surrounding green hills. This unusual formation rarely appears on volcanic islands and creates a striking pocket landscape within the lush terrain.
