Nidom Classic Course - Ikoro is a public, par-72, woodland resort course at the Nidom Classic golf resort in Tomakomai, Hokkaido, Japan, built in 1987. Ikoro is actually a 27-hole facility made up of three combinable 9-hole loops — Ashiri, Pirika, and Kamui — with the Kamui/Pirika combination playing to 6,992 yards from the back tees (73.1 rating, 123 slope). The course once hosted a tournament played by Gary Player and Sam Snead.

Set in "rich forest" (the meaning of "Nidom" in the Ainu language) alongside its sister course, Nispa, the resort totals 45 holes and is just 15 minutes from New Chitose Airport. Facilities include a clubhouse restaurant serving the resort's signature Genghis Khan lamb dish, a tax-free pro shop, a 300-yard, 20-bay driving range, and log cottage accommodation.
