Intangible Folk Cultural Properties Requiring Documentation of Okayama

Omiya Odori is a graceful Bon dance from the Hiruzen Highlands of Maniwa City, Okayama Prefecture, designated a National Important Intangible Folk Cultural Property in 1997 and inscribed on the UNESCO Intangible Cultural Heritage list in 2022 as part of "Furyu-odori." Performed under massive paper lanterns adorned with delicate cut-out shirige decorations, dancers tread wooden floors in geta clogs to the slow rhythm of taiko drums—an unforgettable encounter with rural Japanese tradition that welcomes visitor participation.

Eyo, the sacred naked festivals of southern Okayama, descend from the Buddhist Shushōe ceremony and culminate in thousands of loincloth-clad men competing for two wooden talismans. Selected as a national Intangible Folk Cultural Property in 2003 (with Saidaiji's Eyo further designated in 2016), this living tradition welcomes visitors into one of Japan's most distinctive folk Buddhist customs.

Held every August 2 and 3 at Kibitsuhiko Shrine in Okayama City, the Otaue Festival is a medieval rice-planting rite preserved through the centuries and depicted in a Muromachi-period picture scroll. On the first night, sacred rice seedlings are carried by procession into a pond for the Mitoshiro Shinji ritual; on the second afternoon, towering white banners parade through the precincts in the Ohata Kennō-sai. Designated an Important Intangible Folk Cultural Property by Okayama Prefecture in 1964 and a National Selected Intangible Folk Cultural Property in 1979, this festival is a striking summer celebration in the legendary land of Momotaro.

Hittaka is a traditional fire festival held annually in the Kanaura district of Kasaoka City, Okayama Prefecture. Rooted in the Genpei War of the 12th century, this rare folk event features hundreds of paper lanterns hung on wooden frames to create luminous pictorial designs on two opposing mountainsides. It is designated as a nationally selected intangible folk cultural property.
