Mount Ōmuro

Mount Ōmuro sits at the northwestern base of Mount Fuji and rises to around 1,468 meters with gentle slopes and a crater depression at the top. The mountain contains several wind caves such as Motosu, Omuro, and Kamukura that visitors can explore today.

The mountain formed through volcanic activity and last erupted about 3,300 years ago. Since then it has remained geologically inactive and developed into the quiet peak you see today.

The mountain is called 'Kodaki-Fuji' because of its location next to Mount Fuji, reflecting a Japanese idea about parent-child relationships in nature. You can see this connection when you look at how the two peaks relate to each other from certain viewpoints.

The mountain has no official trails leading to the summit, but the wind caves are open for visitors to explore. Keep in mind this is a protected area, so insects and wildflowers are protected under strict rules.

The mountain contains natural ice caves that hold ice crystals even in summer, showing an unexpected natural phenomenon in this region. These caves offer a rare chance to see ice in an otherwise warm environment.
