Kirifuri Kogen was a ski area located on the eastern slopes of Mt Nyoko to the north of Nikko City in Tochigi Prefecture.

The base was located at an altitude of 1,230m but even so it did not receive huge amounts of snowfall and a number of snow-making machines were used to help out. The lifts at Kirifuri Kogen were also used outside of the winter season for sightseeing.

The ski lifts are now gone but the Kisugedaira Park still opens during the summer months.
