Sanbe Azukihara Buried Forest

The underground museum exhibits enormous cedar trees preserved by volcanic activity, with trunks reaching heights of 10 meters and diameters of 2.5 meters.

Volcanic eruptions from Mount Sanbe approximately 4000 years ago buried this forest under layers of ash and debris, preserving it until its discovery in 1983.

The forest provides direct evidence of the natural environment during the Jomon period, contributing to understanding ancient Japanese landscapes and ecosystems.

Visitors reach the site through a 40-minute bus ride from Odashi Station to the museum entrance, followed by a descent 15 meters underground.

The excavation revealed 30 standing trees and 150 fallen tree fragments, with Japanese cedars comprising 73 percent of the vertical specimens.
