Soma Nomaoi
相馬野馬追Soma Nomaoi is a festival unlike anything else in Japan. For three days in late July, the coastal city of Minamisoma becomes the stage for a spectacle that merges Shinto ritual, samurai military culture, and the thundering power of horses into an event that has no parallel in the nation's festival calendar. More than four hundred riders, clad in full samurai armor and bearing the banners of their ancestral clans, gallop across open fields, compete in mounted races, and scramble to catch sacred flags shot into the air by fireworks, all within a framework of ceremony that dates back more than a thousand years to the military exercises established by Taira no Masakado in the tenth century.
The scale of the event is staggering. The mounted procession that opens the festival stretches for kilometers along the roads of the Soma region, the horses decorated with elaborate tack and the riders wearing armor that ranges from family heirlooms to faithful reproductions, each bearing a nobori flag identifying their shrine affiliation. The sound alone is extraordinary: the clatter of hooves on pavement, the jangling of armor fittings, the shouts of riders controlling spirited horses, and the deep reverberations of conch shell horns that signal the movements of the procession. This is not a pageant performed for cameras but a living practice maintained by families who have raised and ridden horses in this region for generations.
The 2011 earthquake and tsunami devastated the Soma coast and forced the temporary suspension of the festival, and the Fukushima nuclear disaster compounded the crisis by displacing many of the horse-keeping families from their ancestral lands. The revival of Soma Nomaoi in the years following the disaster became a symbol of the region's determination to rebuild not merely its infrastructure but its cultural identity, and the festival now carries an additional layer of meaning as an assertion of continuity against catastrophic disruption.

History & Significance
The origins of Soma Nomaoi are attributed to Taira no Masakado, the rebellious Kanto warrior who, according to tradition, released wild horses onto the Soma plain and used their capture as military training for his mounted warriors in the early tenth century. When Masakado's descendants, the Soma clan, established their domain in what is now the Hamadori coast of Fukushima, they continued the practice and formalized it as a ritual offering to the region's three principal shrines: Ota Shrine, Odaka Shrine, and Nakamura Shrine. The festival's structure, which combines mounted procession, competitive races, and the ritual capture of horses offered to the gods, preserves elements of military training that predate the organized samurai culture of the Kamakura period.
Across a thousand years, Soma Nomaoi has weathered civil wars, the dissolution of the feudal system, modernization, world wars, and natural disasters. Each crisis has threatened the festival's survival, and each time the community has reassembled its horses, armor, and traditions. The designation as an Important Intangible Folk Cultural Property reflects the extraordinary depth of this continuity. The post-2011 revival was particularly significant: with horses scattered, stables destroyed, and families evacuated, the reduced festival that took place in 2012 represented an act of cultural will that drew national attention and support. Today, the festival has returned to something approaching its pre-disaster scale, though the memory of its near-loss has deepened the community's commitment to its preservation.
What to Expect
The festival unfolds over three days, each with a distinct character. The first day centers on the departure ceremonies at each of the three shrines, where riders gather in the predawn hours, their armor illuminated by torchlight, to receive blessings and begin the procession toward the main festival ground at Hibarigahara. The procession itself, winding through the towns and countryside of the Soma region, is best witnessed from roadside positions where the proximity of the armored riders and their massive horses creates a visceral impression of what mounted warfare once looked and sounded like.
The second day is the climax. At Hibarigahara field, the mounted races pit armored riders against one another in heats that recall the competitive training of the feudal era, the horses running at full gallop while their riders manage the weight and restriction of historical armor. The afternoon brings the Shinki Sodatsusen, the sacred flag contest, in which flags are launched skyward by fireworks and the riders scramble on horseback to catch them, a chaotic and thrilling spectacle that combines athletic skill with religious devotion. The successful catchers present their flags to the shrine officials in a ceremony of offering that closes the competitive portion of the day.
The third day is the most intimate. At Odaka Shrine, unarmored riders enter a corral to capture horses with their bare hands, a practice that preserves the original form of Masakado's wild horse exercises. The physicality of the encounter, men wrestling with powerful animals in a confined space, is startling and connects the modern festival directly to its premodern origins. Throughout all three days, the hospitality of the Soma community is evident in the food, the willingness to explain traditions to curious visitors, and the palpable pride with which the families present their horses and their heritage.
