In Iwate Prefecture, an early summer tradition, "Chagu Chagu Mako" was held. About 60 horses dressed in gorgeous costumes paraded along a 14-kilometer route with children on board.
The event has been held since the Edo period to thank the horses who helped with the agricultural work at this time of year when the rice planting is completed. It is said that the sound of the bell decorated on the horse can be heard as "Chou Chagu", so the name came from.
