summer purification rites
Shinto purification ceremony held at shrines on the last day of the sixth lunar month (around the end of June). Also known as 夏越しの祓 (nagoshi no harae).

Minazuki-barae is a Shinto ritual to purify the defilements of the past half year.
I participated in the summer purification rites at the shrine and passed through the ring of cogon grass.
