Hiba Kojin Kagura: A Sacred Ritual Dance of Ancestral Worship in the Mountains of Hiroshima

Deep in the mountainous Tojo and Saijo districts of Shobara City in northeastern Hiroshima Prefecture, a powerful and ancient form of sacred dance called Hiba Kojin Kagura has been performed for centuries. Designated as an Important Intangible Folk Cultural Property of Japan in 1979, this extraordinary ritual kagura is dedicated to Motoyama Sanpo Kojin, an ancestral deity who serves as the guardian spirit and tutelary god of the local communities. Unlike many kagura traditions that have been adapted for entertainment, Hiba Kojin Kagura retains deep religious significance rooted in medieval land-based belief systems, making it one of the most ritually authentic kagura performances surviving in Japan today.

Historical Background

The origins of Hiba Kojin Kagura are intimately tied to the medieval social structure of the Hiba region. In this area, an ancient communal land unit called "myo" (名) has survived from the medieval period largely intact. Each myo community centers its spiritual life around the worship of Motoyama Sanpo Kojin, who functions as the collective ancestral spirit, guardian deity, and ubusunagami (local birth deity) of the entire myo. Because of the profound reverence for this deity, the kagura rituals dedicated to Kojin have been performed with the utmost solemnity and grandeur throughout the generations.

The kagura tradition was first recognized by the national government in 1971, when it was selected as a folk cultural property requiring documentation. In 1979, it received its formal designation as an Important Intangible Folk Cultural Property, acknowledging its exceptional value as a living tradition of ritual performing arts. The Hiba Kojin Kagura Preservation Society, based in Kawahigashi in Tojo-cho, serves as the officially recognized custodian of this tradition.

Why It Was Designated: Cultural and Historical Significance

Several factors contributed to Hiba Kojin Kagura's designation as a nationally important cultural property. First, it is a form of torimono kagura (sacred dance performed with ritual implements) that displays remarkably strong regional characteristics. The kagura preserves elements of chinkon (spirit pacification) rituals, a practice with deep roots in Japanese religious history. Most significantly, it maintains the tradition of takusen — divine oracles delivered through spirit possession — which is exceedingly rare among surviving kagura traditions nationwide. The combination of these ancient ritual elements within a single, continuously practiced performance tradition makes Hiba Kojin Kagura invaluable to scholars of Japanese performing arts history and folk religion.

Structure and Highlights of the Performance

Hiba Kojin Kagura is performed in two principal formats depending on the ceremonial occasion. A grand kagura (dai-kagura) lasting four days is held during shikinen — cyclical years determined by each myo community's tradition, typically at intervals of 7, 9, 13, 17, or 33 years from the previous grand ceremony. In other years, a smaller two-day, one-night kagura (ko-kagura) is performed.

The performance unfolds in three major phases. The mae-kagura (preliminary kagura) involves welcoming the Kojin deity to the otoya (head household) and performing ritual purification dances including yutate (hot water rituals). The hon-kagura (main kagura) features the Shichiza Shinji (Seven Seat Rites) and shinno (sacred plays) depicting mythological narratives such as Orochi Taiji (the slaying of the great serpent), Iwato Biraki (the opening of the heavenly rock cave), Taisha, Kojin, and Yamato Takeru. This phase also includes the gogyomai (five-element dance) and the dramatic kamigakari takusen, in which a priest enters a state of divine possession and delivers oracles. The hai-kagura (ash kagura) concludes the entire ritual with spectacular scenes including mochitori (rice cake snatching), where participants scramble for rice cakes amid swirling ash and flying embers.

Traditionally, the performance took place in a specially constructed high platform called kodono, erected in the middle of rice paddies. While modern performances sometimes use shrine worship halls or private homes instead, the ritual structure has been carefully preserved.

Visitor Information

Hiba Kojin Kagura can be experienced at several regular events throughout the year. A miyakagura (shrine kagura) is performed on the first Saturday of October at Shishiyama Hachiman Shrine in Tesseicho, Niimi City, Okayama Prefecture. Another regular performance takes place on the third Saturday of November at Nuka Shrine in Tojo-cho, Shobara City, continuing from evening through early morning. In December, the Hiba Kojin Kagura Festival is held in Tojo-cho. Additional performances occur at regional events including the Taishakukyo Lake Opening in late April and the Fureai Tojo Festival in mid-October.

Grand kagura ceremonies on shikinen years are particularly spectacular but occur irregularly, so visitors should check with the Shobara City Board of Education or the Hiba Kojin Kagura Preservation Society for the latest schedule.

To reach the Tojo area, take the Chugoku Expressway to Tojo Interchange. From Hiroshima Station, high-speed buses operated by Bihoku Kotsu run to Tojo Station (approximately 160 minutes). JR Geibi Line trains also serve Tojo Station. From Tojo Station, local taxis provide access to specific performance venues.

Surrounding Attractions

The Tojo area of Shobara City offers visitors much more than kagura. Taishakukyo Gorge, one of Japan's most celebrated scenic spots, lies just 15 minutes by car from Tojo IC. This 18-kilometer-long limestone gorge features Onbashi, a natural stone bridge 90 meters long and 40 meters high designated as a National Natural Monument and counted among the world's three great natural bridges. Visitors can explore the Hakuundo limestone cave, take boat cruises on Shinryuko Lake, or enjoy kayaking and other outdoor activities.

The historic townscape of Tojo itself preserves Edo and Meiji-era merchant houses, including the elegant Sanrakuso (former Hozawa residence), built in 1891 with distinctive yatsumune-zukuri architecture. The area is also known for apple orchards, sake breweries, and seasonal foods from the surrounding mountains.

Nearby Hiba Mountain, said to be the burial place of the goddess Izanami according to Japanese mythology, offers hiking trails through pristine beech forests within the Hiba-Dogo-Taishaku Quasi-National Park.
