Anba Bayashi: A 300-Year-Old Healing Music from the Heart of Ibaraki

Deep in the rural reaches of Inashiki City, Ibaraki Prefecture, the stirring rhythms of drums and gongs still echo across the rice fields each summer. This is Anba Bayashi (あんば囃子) — a folk musical tradition rooted in the venerable Ōsugi Shrine, beloved across eastern Japan as "Anba-sama." For centuries, fishermen, sailors, and farmers along the Pacific coast and the Tone River system have turned to these vibrant melodies in search of protection from disease and safe passage on stormy waters. In 1978, the Japanese government formally selected Anba Bayashi as an intangible folk cultural property requiring documentation, recognizing it as a living treasure of regional heritage.

For international travelers seeking an authentic encounter with rural Japanese spirituality — beyond the well-trodden paths of Kyoto and Tokyo — Anba Bayashi offers a window into a folk world where music, faith, and community remain woven together as they have been for generations.

The Legend Behind the Music

To understand Anba Bayashi, one must first know about Ōsugi Shrine, the spiritual home from which this tradition was born. The shrine sits in the Aba district of Inashiki City and is said to have been founded in the year 767, during the Nara period, when the wandering monk Shōdō Shōnin passed through the region on his way to open the sacred Mount Nikkō. Encountering villagers stricken by a deadly epidemic, Shōdō prayed beneath a colossal cedar tree and invoked the deities of Mount Miwa — and miraculously, the people recovered.

From that day forward, Ōsugi Shrine became revered as "Akuma-barae no Anba-sama" (Anba-sama, the Demon-Banisher). The name "Anba" itself comes from the ancient peninsula known as Anba-jima, recorded in the eighth-century geographic chronicle Hitachi Fudoki, which once jutted into a vast inland sea where Lake Kasumigaura now lies. The towering cedars of the shrine served as natural sea-marks for fishermen navigating these waters, and the spirit dwelling among them became guardian of all who lived by the sea.

From Plague-Banishing Ritual to National Folk Treasure

The bayashi (festival music) we know today is said to have grown from a deeply earnest ritual practice. Whenever signs of smallpox — then a terrifying scourge — appeared in surrounding villages, residents would borrow a tengu mask (representing the fearsome long-nosed mountain spirit) from Ōsugi Shrine. Carrying the mask through their settlements while striking gongs and beating drums, they would parade from house to house, the clamor of percussion meant to drive evil influences out of the community. This protective procession is considered the prototype of Anba Bayashi.

By the early Edo period, the music had taken on a life of its own. Records suggest the term "Akuma-barae Bayashi" (demon-banishing music) appeared around 1725, while some accounts trace earlier roots to 1617, when a merchant is said to have brought a related musical tradition from Kishū together with twelve-seat kagura sacred dance. As Anba-sama worship spread along the Pacific coastline and through the river networks of the Kantō region, the music traveled with it.

Highlights and What to Look For

Visiting Tips and Surrounding Attractions

Inashiki City lies in southern Ibaraki, easily combined with a visit to nearby Lake Kasumigaura, Japan's second-largest lake. Visitors are encouraged to confirm festival dates directly with Ōsugi Shrine or the Inashiki City Tourism Association, as performance schedules may vary year to year and not every appearance of Anba Bayashi is open to the general public.

Other attractions in the area include: the dramatic stone Buddhas of Yatsuko, the wetlands and waterfowl of Ukishima, the springtime tulip fields of Inashiki, and the leisurely waterways of the wider Suigō region — a gentle, water-rich landscape that feels quietly removed from the rush of metropolitan Japan.

• Ōsugi Shrine main precinct — open year-round; the shrine is famed nationally as a "dream-fulfilling" deity (yume-musubi).
• Suigō-Tsukuba Quasi-National Park — a network of rivers, lakes, and rice plains.
• Lake Kasumigaura — boat tours and lakeside cycling routes nearby.
• Miho Training Center — a top-tier JRA horse-racing facility (limited access; check tour availability).
