Hachinohe Sansha Taisai (八戸三社大祭) is a Japanese festival celebrated from July 31 to August 4 in Hachinohe, Aomori Prefecture, Japan. Its rites center on three Shinto shrines: Ogami (霊神社), Shinra (新羅神社), and Shinmei (神明宮) shrines. There is a procession of twenty-seven floats and three mikoshi are also borne through the streets. It has a two hundred and ninety-year history and in 2004 was designated an Important Intangible Folk Cultural Property.[1][2]
On August 2, the Chojasan Shinra Shrine holds the annual Kiba Dakyuu (騎馬打球) tournament. It is the traditional Kagami-style dakyu and is held only in Hachinohe, Yamagata Prefecture, and the Imperial Household Agency.[3]
