is located on the south-eastern slopes of Mt Kosha in Yamanouchi town, in the north-eastern region of Nagano Prefecture.
In recent seasons, Yomase Onsen was one of five connected ski hills on the slopes of Mt Kosha that were branded as 'Mt Kosha' and joint lift tickets were available. However, since the 2016-2017 season there have been various changes. For the 2018-2019 season the big ‘Mt Kosha’ concept seems to have fractured further. See lift ticket information below for details on Yomase Onsen lift tickets for the 2018-2019 season.
Yomase Onsen and X-JAM Takaifuji
offer a joint ticket; Kita Shinshu Kijimadaira
and Makinoiri Snow Park
are both operating independently, and Yamabiko-no-oka
is continues to be closed. A ticket that is also valid at nearby Ryuoo Ski Park and Komaruyama is available.
In the regions surrounding Mt Kosha, Myoko and Madarao Kogen are to the west, Nozawa Onsen is to the north and Shiga Kogen is to south west.
