Hattaro Oshimako is a Bon dance performed to the Oshimako-bushi song, traditionally passed down in the Hattaro district. Participants form a circle in open spaces or shrine grounds and dance without musical instruments, using only the singing and the sounds of their feet scraping the ground as accompaniment. The song follows a 7-7-7-5 syllabic pattern and features a distinctive call-and-response style with overlapping voices. This dance not only preserves the old vocal style of the Oshimako-bushi from the Hachinohe region but also maintains the ancient form of Bon dances characteristic of the area, performed without musical instruments.

To pray for a bountiful harvest, hand movements represent abundant rice ears, while turning the palms to symbolize poor crops is avoided because it recalls famine and is considered taboo.

The preservation society actively promotes Hattaro Oshimako as well as other traditional dances like Jurokashi and Sasananyadoyara. Today, many local residents—from children to adults—enjoy participating. The dance is also performed at events such as the annual Oda Hachiman Shrine Festival in September. Hattaro Oshimako is designated as an Intangible Folk Cultural Asset by Hachinohe City.
