An all-weather indoor park built around nature, animals and science, so rain makes no difference to the day. It divides into five areas, from the Forest Exploration Plaza to the Space Athletic in the basement. A wooden toy room and a book and art corner fill out the rest. Shoes come off in the forest plaza and the Space Athletic; indoor shoes are not needed. The building stands beside Joyama Park, a walk from Zenkojishita station.
