And as one of events of Kamakura, snow caves are made. Because of this, snow cave itself is also called "Kamakura" in general and that is made for tourism regardless of the ceremony in the snowy regions.
Kamakura of Yokote[横手（よこて）] City is the most famous and that has about 450-year history. That is held on February 15 and 16 every year.
In snow cave "Kamakura" where an altar enshrining the god of water(Suijin or Mizugami[水神]) is set up, children say to visitors, "Haittanse[はいったんせ]" and "Ogandanse[おがんだんせ]"(These are dialects of Akita. Haittanse means "Please come in" and Ogandanse means "Please pray to god". ) and serve them Mochi[餅（もち）](rice cake) and Ama-zake[甘酒（あまざけ）](sweet low-alcohol Sake made from fermented rice.). And visitors offer money to the god and pray.
