Iizuna Kogen was located to the north of Nagano City on the southern slopes of Mt Iizuna, between the still-operating Togakushi on the western slopes and Iizuna Resort on the eastern slopes of the same mountain.
Iizuna Kogen was owned by the city and was popular with locals. The Moguls events of the 1998 Nagano Winter Olympics were held on the F Course and Tae Satoya won the gold medal. Subsequently, the course was named after her.
In recent years Iizuna Kogen struggled with snowfall and made various changes to lift and course operations. The last day of operation was 16th February 2020.
