A theme park located in Omae-hosohara, Tsumagoi Village, you’ll find plenty of attractions here, including the “Toy Room Area,” which is filled with toys from across all eras, the “Nature Athletic Area,” which utilizes Karuizawa’s natural scenery to provide entertainment, and the “Attraction Area,” which has something for children of all ages.
