Take the forest road Fuchigasawa Line from the Toyofusa Lake (Toyofusa Dam) side to Toyofusa Great Falls.
Walk along the stream to Toyofusa Great Falls. It was a larger waterfall than I expected.
After that, I toured the remainder of the Fuchigasawa Line and the Fuchigasawa Okuyone Line.
It is said that you can swim in the waterfall basin in summer at Toyofusa Great Falls.
