Mt Kumotori is the highest point of Tokyo prefecture, first climbed in December 2006, and then again in December 2013 and 2015, staying in the summit hut each time. The purpose of my last 2 visits was for Hatsuhinode. The 2 main trails leading to the summit start from Okutama Lake in Tokyo and Mitsumine Shrine in Saitama and can be reached by bus from Okutama and Chichibu stations respectively; both are best done with an overnight stay in the summit lodge. The panoramic view of the Okutama and Chichibu mountains, as well as Mt Fuji, is definitely worth the effort of the lengthy ascent. Due to its relatively high elevation, the summit area has snow and ice in the winter months and crampons are recommended if climbing in that season.
