The 100 Famous Mountains of Yamanashi (山梨百名山, Yamanashi Hyakumeizan) are a list of 100 famous mountains in Yamanashi, selected in 1997 by the Yamanashi prefecture. When the 100 Famous Japanese Mountains are looking a little bit out of reach, Tokyo-dwellers might find the Yamanashi 100 to be a bit more of an accessible option.
Being in Yamanashi, some of these mountains also have great views of Mt Fuji! To date, I've climbed 32/100.
