"the Buddhism is more spreaded today"
not so much here in Japan. We still have some influences by Shintoism
Shintoism is a kind of animism.
very different from "One God religion" like Christianity, Islam, etc.
There are many kind of God. like "God of fire" " God of sun" etc.
Most famous God is "AMATERASU OOMI KAMI", I think.
And there are many stories and denominations.
"OTERA""お寺" = temple = buddism
"JINJYA""神社" = shrine = Shintoism
Most of japanese go to shrine every first day of a new year("元旦""gantan")
and celebrate the day by shintoism style.I mean "OSECHI RYOURI" "KADOMATSU" etc.
Some of japanese marrige by Sintoism style.
Most of japanese marrige by Christian style.
Most of japanese celebrate Christmas and Valentine's Day very showily.
Most of japanese are buried by Buddism style.
We are weird ppl
