Sweet spot: April, May, November. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
💡 Good to know
- Comfortable walking conditions are most likely in spring and from late summer into autumn. The route still requires a live trail and weather check, especially after heavy rain.
- Frequent rain makes June and early July less comfortable. Carry rain gear, check trail conditions and use the parallel JR Chuo line if the walking section is unsafe.
