A new family area called "Wanpaku Republic" is set to open at Seibuen Amusement Park in Tokorozawa, Saitama this summer 2026.
The new area will be situated between the existing family zones "Let's Go! Leo Land" and "Yuhi no Oka Playland," creating a more unified family-friendly experience throughout the park. The colorful world of Wanpaku Republic is designed to give children an immersive, time-flies kind of experience that keeps them fully engaged.
Among the highlights are a roughly 14-meter-tall nostalgic toy sculpture and a roller slider stretching approximately 40 meters in length — both attractions that parents and children can enjoy together.
