The Saitama Museum of Rivers only started celebrating Halloween around 8 or 9 years ago, and then a series of events prevented them from having Halloween festivities since 2018. In summary – a typhoon in 2019 and then the pandemic! However, they are celebrating in 2022 and on four different dates (see information section).

Kawahaku Halloween

In Japanese the Saitama Museum of Rivers is Kawa no Hakubutsukan. It is nicknamed / called Kawahaku for short.

For people who come to the Saitama Museum of Rivers in costume on those days, they will get a present. They don’t specify what that present is this year. In a previous year, it was a free ticket for the Adventure Theatre.

This year there are five events. For children in costume who participate in all five Halloween events they will get a present from the museum.

The events are:

  • a Halloween stamp rally
  • Halloween photo spot
  • Halloween craft – this year its Halloween costumes
  • Spot the difference
  • Find the mascot – the museum’s mascot “Kawashirou” is dressed up as a witch and hiding in the museum
