Kamoi Hachiman Shrine Donbaki is an event called “Mondayaki”. It is a sanctuary to burn ancient plates, amulets, pines, etc. on the beach in front of the sanctuary.
Although there is a desire to have a “Sato” event as a holiday, it is an event that must be done in the “New Year” originally, and if the date changes it will not make sense.
