About
Mount Mihara rises inside a large caldera in the middle of Izu Oshima, reached by jetfoil from Takeshiba in under two hours. A paved path leads from the Mihara-sancho-guchi bus stop across lava fields to the crater, and a loop trail circles the rim; the bare black slopes on the island's east side are known as Ura-sabaku.
Highlights
- Crater-rim walk around an active volcano
- Lava fields from the 1986 eruption
- Black volcanic 'Ura-sabaku'
- Views of Mount Fuji across the sea
Tips
- Jetfoil from Takeshiba pier (Tokyo) about 1h45
