I had a chance to stay in Kamikochi, at the foot of the Japan Alps. Kamikochi is popular for a carless resort and for the hiking courses you can enjoy in a national park, but many tourists visit only in the daytime.
But, its natural beauty in the evening and morning is awesome.
Kamikochi is located between Takayama and Matsumoto, two spots popular among foreign travelers and you can visit by bus from both towns.
