On the morning we went, we attended a playgroup, which was a great way to learn Japanese songs and meet new friends. We also had an amazing time running around the huge gym all by ourselves. What a novelty in Tokyo!

Nandemo is truly a kids-to-teens hall as there is definitely something for every age of child. Their website has a list of the monthly calendar of events and newsletter in English. The WaiWai Sports Club is a gym class for children aged 3-6, held every Thursday from 2:30-3:30pm, which is also free.
