Japan is a very clean and respectful society, so please do your best to minimize your waste and footprint that you leave behind.
Some of the hiking can be a bit difficult, so being in decent shape before undertaking a hike will be of great benefit.
Very cold in Winter months, with temperatures rarely getting above freezing. Pleasantly warm Summers.
5-7 hour bus/car from Tokyo, 1.5 hour train and bus from Matsumoto to Kamikochi.
April-November, to avoid the extreme cold of Winter.
Stay up-to-date on the best adventures!
