Japanese Coming-of-age Practice
When a girl has her period for her first time, in Japanese culture, a big celebration is held. There is a special dinner of red beans and rice served that everyone must take a bite of to take part in the celebration and honor the passing of the girl into the adult world as a woman.
The informant was very embarrassed about the tradition and how the family made a big deal about her becoming a woman. She believes that everyone must eat the red rice and beans as a physical acknowledgement and celebration of the girl becoming a woman within her family and society as a whole.
I agree with my informants analysis. Also, though its quite obvious, the coloring of the beans and rice with red dye is supposed to reflect the physical act of menstruating that begins with a girls first period. The reason why I think this celebration is so important and celebrated as a passage into adulthood is because, with a girls first period, she is now physically able to bear children.
