You heard right. Called "Omiyuki-san" it is an over 1000 year ritual on April the 15th for men in the city of Kai of the Yamanashi prefecture dress in pink female kimonos and stomp on the dikes in order reinforce the ground.
It is said that reason for the drag is to not scare away the female god with the presence of men. Yes, so it's like a 1000 year old Japanese Mrs. Doubtfire ritual! Awesome!
