William As the (very proud) father of a daughter, I observe Hina Matsuri every year. Generally, offerings are offset at rivers following the festival. Though the sentiment is understood - that one’s daughter mist follow the flow of life bestowed to her - we keep hers here and set them up every year. Her home is here, and it will remain so, wherever for for however long she she may live. She is a true Higokko. Encourage your children to embrace that identity. https://www.nippon.com/en/features/jg00031/
