Iwanuma City Children Play and Exchange Base miiina Water Play Plaza

About this spot

This is the Iwanuma City Children Play and Exchange Base miiina Water Play Plaza in Iwanuma City, Miyagi Prefecture. Outdoors there are water-play and mud-play areas where children can throw themselves into scooping water and kneading mud, the kind of play they get most absorbed in. Indoors there is water-play equipment introduced for the first time in the Tohoku region along with a ball pool, in an indoor play space of roughly 2,300 square meters. With water-play areas both outdoors and indoors, neither sudden rain nor overly strong sunshine will derail your plans. Admission is 300 yen for city residents and 600 yen for non-residents, and the facility is open from 9:00 to 17:00, extended to 18:00 in summer. It is closed on the 2nd and 4th Tuesdays and over the New Year period, so plan around those days.

Tips

The opening period has not been announced; in past years it has operated during the summer holidays. Check the Iwanuma City information for the situation on the day before you set out. Outdoors everyone gets muddy, so bring plenty of spare clothes and always pack plastic bags for dirty clothing and shoes. There is a rule about rinsing off the mud thoroughly before moving indoors, so follow the on-site instructions. Even where the water is shallow, never take your eyes off the children and always have an adult accompanying them. Closed days are the 2nd and 4th Tuesdays, so if you are going on a Tuesday be sure to check the date.

Best time to visit

About 3 hours 35 minutes. The afternoon, when the sunlight softens, is recommended
