Hello! I'd like to know more details about Onbashira Matsuri. As I've understood, the next will be in 2022. The dates of the festival are not exact yet, but the frames of the event seems to be too wide - April and May. The described event can't happen every day, so I'd like to know if they occure on a certain day or on a weekend? I coudn't find the exact information how it's better to watch it.
