A shrine or temple has a large box called “Saison-bako” set up.Ā People throw money there when they make a wish to God or Buddha.Ā This custom is “Osaisenļ¼ćč³½éļ¼”.
The amount to be charged is not decided, but many people like 5 yen coins.Ā This is because 5 yen is said to be suitable for Osaisen. Because “5 yen” is the same pronunciation as Japanese as “Go-en” representing connection and relationship.
But those who expect big returns seem to throw a larger amount.
