its beautiful place to enjoy real nature. its called `rausu-dake` which require to walk over 2-3hours per one-way. u will work following `kemono-michi` which is a natural path made by animals foot prints. when you go into the place, u need to be with nature guide carrying `bell` to avoid bears which may come across by chance. never go into the woods alone since there will be the posibility of beling lost cause there is no major path across the mountain. cold even in summer and full of woods, glass, leaves so wear appropriate walking cloths.
