Anetai Kozuya Nesori no keikaboku chitai

Anetai Kozuya Nesori no keikaboku chitai is a site containing petrified wood specimens embedded in geological layers along the Mabechi River. The fossilized remains reveal how plant material transformed into silicified stone through natural processes over vast periods of time.

The site gained official status as a Natural Monument of Japan in 1936 and was elevated to Special Natural Monument designation in 1952. These designations reflect the importance of the location for understanding the region's geological past.

Parts of the petrified wood from this location were incorporated into the construction of the former Nesori Elementary School, connecting geology with local education.

The site features marked paths that guide visitors through the different petrified wood specimens on the grounds. Access and viewing conditions can vary depending on weather and seasonal changes in the area.

Some petrified wood samples from this location were originally incorporated as building material in a nearby school structure. This practical reuse connects the geological resources of the area with local construction history.
