The Chagu-Chagu-Umako Fesival is a parade that begins at Onikoshi-souzen Shrine in Takizawa and finishes at Hachiman Shrine in Morioka, Iwate Prefecture.

The festival is held on the second Saturday of June each year. About 100 local horses decorated in colorful outfits slowly parade as part of the festival.

The festival is held to pray for the safety of both people and horses, as this was traditionally a horse-breeding area. This festival goes back to feudal times when houses in the local Nanbu-Magariya style incorporated features for the excellent care of horses.

It is believed that the Chagu-Chagu-Umako Festival was originally a time to rest horses in the off-seasons, and developed into the parade seen today.

'Chagu-chagu' is the name of the bells hanging from the necks of the horses. The sound of their jingling in early summer has been selected as one of Japan's 100 scenes with sound, and has also been designated as an intangible folklore cultural asset of the nation.
