Saitama Summer Pools 2026 年の埼玉県屋外プール22選。Information for twenty-two pools that are open and where is not. Dates and conditions included. Plus each of Saitama’s outdoor seasonal pools mapped together on a Google MyMap.
⚠There are no tickets at the gate at most of the prefectural or Saitama City municipal outdoor / seasonal pools in 2026. You need to buy the tickets either at a 7-11 or online. In addition, many of the private outdoor pools also require that you purchase tickets in advance. In other words, in 2026, there are only a handful of pools that sell tickets at the gate.
Summer Pools that are closed in 2026
The pools that closed permanently during the pandemic:
- The main Saitama Prefectural pool in Ageo closed permanently during the pandemic. The Ageo Undo Park is still open though (and it has a new playground!), just the pools are closed.
- Unfortunately, the prefectural aqua park was not the only popular pool to close permanently. Fujimi Garden Beach also closed its doors permanently in 2021.
- Owada Family pools in Niiza also closed their doors permanently in 2022. However, they are planning to rebuild, in a separate area from my understanding, but that will take a few years. The latest on this plan from Niiza City from April 2022.
- On May 23rd 2022 Kumagaya City posted to say that the outdoor pool at Kumagaya Sakura Undo Koen would “cease to operate” in 2022 due to the old age (50+ years) of the pools.
- In 2021, Kawaguchi Green Center said that say that due to the old age of their pools they would be closed indefinitely. Then in the summer of 2022 they finally made an announcement that the pools are to be torn down and replaced with a parking lot.
- Yoshikawa City also decided to tear down their pools due to old age!
- Numakage Pools operated for the last time ever in the summer of 2023 and closed permanently after the season, after 52 years of operation. However, the outdoor baby pool only was open in the summer of 2024. More information (Japanese language).
- Kuki’s citizen pool is to be torn down and rebuilt in the coming years.
And pools that are closed long term:
- Sakado Outdoor Pools / Aqua park. In 2022, according to the official Sakado City website, the seasonal outdoor pools were undergoing renovations. In 2023, 2024 and again this year, they have said they will not open.
- Hatsukari Park in Kawagoe has not opened since 2019. There is no announcement yet for 2026.
- Chichibu Muse Park pool was closed between 2020 and 2022, opened briefly in 2023, but was closed in 2024 and 2025. They have announced that the pools will not open in 2026 either.

>>Saitama Pools ・ Seasonal Pools ・Outdoor Pools・ Aqua parks <<
Visiting one of Saitama’s outdoor summer pools is a fun way to cool down in the ridiculously high summer temperatures. Do you go to aqua parks or outdoor pools during the summer? Any you would like to recommend?

ooooh i wish it was summer time! So many outdoor options!
I’m sooooo glad they are opening some pools this year… hopefully not famous last words – the “Delta Strain” has started to do the rounds so they could all be closed down before they open!!
I’m wondering about parks with splash pools. Like Shinrinkoen in Higashimatsuyama or the one in the kid’s zoo there.
Last check, last week – they aren’t planning to open this year : ( Shinrin says both the splash pools and the newer wading river “closed indefinitely”. The zoo had no info either way at the time which I interpret as a “no”!!
For anyone in Toda city, I asked at the Primrose centre, and they said they’re planning to open their small pool after rainy season has finished. Likely to be restricted times (they mentioned 10-12 for pre-school kids – my child is 4), but this isn’t confirmed I think.
Thank you so much for sharing that information <3
