軽井沢おもちゃ王国
群馬県・嬬恋村・Amusement parkSeasonal
Oversized vehicles (campervans)： The operator publishes nothing about oversized vehicles. We do not guess — call the facility before you go.
This toy-themed park is located at Ohsakihosobara, Tsumagoi Village, Agatsuma District, Gunma Prefecture; despite carrying the name "Karuizawa," it actually sits on the Kita-Karuizawa side. The official Hotel Green Plaza Karuizawa shares the same grounds. The park is said to cover an area equivalent to one Tokyo Dome and includes more than 12 indoor "toy rooms," an athletic course billed as the largest in the northern Kanto region with about 120 elements ("Waku Waku Great Adventure Forest"), and more than 12 kinds of rides such as a Ferris wheel, go-karts, and a coaster. Admission is 1,300 yen for junior high age and up, 1,000 yen for ages 2 through elementary school, and free for ages 0-1; a free pass (covering rides and the adventure forest) costs 3,300 yen for adults and 3,100 yen for children. The winter closure is planned for November 24, 2026 to early April 2027.
