On 30 June every year, Kochi’s Wanuke-sama festivals are held at shrines in and around Kochi Prefecture. Wa (circles or hoops) are made from chigaya (Rhizoma Imperatae). You are supposed to go through this circle three times in total in order to keep safe and sound throughout the year.
When you go out for Wanuke-sama, I recommend you wear Yukata (Japanese light kimono for summer) if you want to be more Japanese. If so, you might be able to understand Kochi’s tradition and culture more.
