Takahara is a small stratovolcano located SW of Nasu volcano and NNW of Utsunomiya city in central Honshu.
The basaltic-to-dacitic volcano is constructed within the Shiobara caldera. It contains a number of small lava domes, including the symmetrical Fuji-san, one of many conical volcanic mountains named after Japan's renowned Mount Fuji.
Fuji-san is the youngest known volcanic feature of Takahara volcano and was formed about 6,500 years ago.

Beschreibung:

The Shiobara caldera was formed more than 10,000 years ago, and corresponds to the Otawara pumice-flow deposit.
The latest dated eruption of Takahara took place about 6500 years ago along the NW-SE-trending Yumoto-Shiobara fissure system within the caldera. Eruptions along this fissure initially produced the phreatic Takahara-Uenohara tephra deposit distributed primarily to the east. The eruption ended with the construction of Fuji-san lava dome.
