“Chagu Chagu Umakko is a horse festival in Iwate Prefecture, Japan. Held on the second Saturday in June, approximately 100 horses with colourful fittings and bells parade depart from Onikoshi Sozen Shrine in Takizawa to Morioka Hachiman-gū. The term chagu-chagu is an onomatopoeic expression for the sound made by the horses’ bells.”
