Chagu Chagu Umako Matsuri

The "Chagu Chagu Umako Matsuri" (festival of the 'small' jingling horses) takes place on the second Saturday of June in Takizawa village & Morioka-city, Iwate prefecture in Tohoku region (northern Japan). 100 horses parade in a merry jingling of bells from a mountain village down to the town. The name "Chagu Chagu" is an onomatopeic expression refering to the bells sounding as the horses trot along.
