Hanasaki summer pools

The Hanasaki Summer Pools, aka water or aqua park, are as family and child friendly as the park they are in: Kazo Hanasaki Park. Hanasaki Aqua park is one of the three remaining prefectural pools. Unfortunately, the main Saitama Prefectural Pool in Ageo closed permanently in 2021. The pools in Hanasaki (Kazo) are not as large as the other two remaining pools in Kawagoe and Koshigaya. But they are colorful and fun for kids. Please note that in 2024, like in 2022 and 2023, you have to purchase a ticket in advance from a 7-11 or Asoview.

Hanasaki Park has lots of things for families to enjoy. You can read about all the facilities the park has to offer here. The two most popular attractions are the bikes (and pedal cars) and the pools. However, the pools only open during the summer holidays. They are all outdoor; its quite like what we call an aqua or water park in Europe.
