NPO. HOJO no MORI website:


HOJO no MORI owns a hut and a special field nearby Lake Yamanakako in Yamanashi prefecture, surrounded by forest. The hut, the base for its activities, is located in a fully natural environment encompassing the Mt. Fuji and Tanzawa mountain areas. You can enjoy a quiet atmosphere there. When the season comes, plentiful edible mountain herbs and mushrooms may be gathered. A stream runs through this area and it is utiltized as drinking water. The hut is set as a base and you can enjoy various outdoor menus, such as gathering edible wild plants

Today, it is said that nature in the Earth suffers. That in Japan is not an exception. We are not allowed to deteriorate Japan’s original scenery which our ancestors have been preserving. To preserve it, please acquire the good method of the conversation with nature. HOJO-no-MORI does the help. DO make a visit to our lodge!

Mountaineering Guide: Mr. Kimura Masayuki, qualified Forest Instructor. His hunting experience is more than 20 years. During the season, he hunts deer and wild boar around this area. His hunting stories would enchant you. Some of our routes are created by him, which are for wild animals, not on a hiking map.
