Mount Fuji's 2026 climbing season has come to an end. The four official routes to the summit closed on September 10. Using the closed sections of these trails is now prohibited.

This prohibition is enforced under Japan's Road Act. Penalties for violating this act can be severe, with punishments including up to six months in prison.

Further details on the closure and its implications are available from the source. The end of the climbing season marks an important change for those who use the trails.
