Every year, Tokyoites flock to Yomiuri Land’s epic Pool Wai to stay cool in the summer. This waterpark features five massive outdoor pools with thrilling mega slides as well as wave and diving pools, so you can easily spend an entire day here. While the daytime attracts families with children, the evening is much more relaxed and quiet. This year’s pool event is themed after Korean girl group Niziu, and it features a spectacular water show at 7pm and 7.30pm with nine colours to represent each member of the K-pop group。
Entry to the night pool is significantly cheaper than peak hours during the day. It only sets you back ¥2,000 to take a dip from 5.30pm to 8.30pm.
