Seibu Pools Shirakobato Park Festival

Seibu Yuenchi Amusement Park have confirmed that their pools will open from July 10th to September 5th in 2021. Last year, 2020, Seibu Yuenchi was one of only three pools that opened. This year more but not all of Saitama’s summer pools will open. You can see which are opening and which are not here. Most of them are only opening for four weeks, so Seibuen’s pools are one of the longest in 2021.
