Spent the night before in the parking space under heavy rain due to a typhoon. Began early in the morning from Ichinosawa tozanguchi (一ノ沢登山口), straight up to Jonen goya (常念小屋). There, in a perfect, clean day, turned left for the summit!!! Magic, extraordinary view all over Hotaka dake, Yarigatake, and Daikiretto!!
