I found the trail to be fairly easy. Maybe bit too easy, as I got off the trail for a bit until I passed a fallen tree I didn't remember to have crossed on the way up. Just to the top of mount honjagamaru there were a bit rocky places, that will be difficult when they are wet. In dry weather it's no issue if you are careful. The views are great and must be even better if you can see mount Fuji. Unfortunately it was shy this day and hid mainly behind clouds. On the other hand, thus it wasn't that hot.
