This circuit climbs from Minotoguchi over Mount Okoya to Mount Amida, then traverses Mount Naka, Mount Aka, Mount Yoko and Mount Io before descending through Akadake Kosen and Minoto. It links the highest summit of Yatsugatake with Mount Yoko's exposed, chain-assisted rock ridge and Mount Io's immense crater wall in one long and demanding alpine route.
