Few sights in Japan hit as hard as the opening charge of Soma Nomaoi. Imagine five hundred horses, their riders clad head-to-toe in Edo-period samurai armor, galloping full-speed across a dusty plain while battle flags snap in the wind. The thunder of hooves shakes your ribs. The crowd roars. For a few breathless seconds, the boundary between the 21st century and the age of the samurai dissolves entirely.
This is Soma Nomaoi, and it has been happening in what is now Fukushima Prefecture for over a thousand years.
A Festival Born from Battlefield Training
The origins of Soma Nomaoi trace back to the Heian period, when Taira no Kojiro Masakado — a rebellious warlord who briefly declared himself emperor — released wild horses across the Soma plain and ordered his warriors to capture them as military training. That was around the year 940. The Soma clan, his descendants, continued the tradition century after century, and it evolved into a religious offering to the local Myoken shrines. Even through wars, famines, and the devastation of the 2011 earthquake and tsunami, Soma Nomaoi never stopped entirely. In 2012, barely a year after the disaster struck the Fukushima coast, a scaled-down version rode on — an act of defiance and resilience that still resonates today.
Four Days of Thunder (May 22-25, 2026)
The festival unfolds across the towns of Minamisoma and Soma over four packed days. Each day has its own character.
Day 1 — Departure Ceremony (Odekake, May 22) The festival begins at the three Myoken shrines: Ota Shrine, Odaka Shrine, and Nakamura Shrine. Horsemen gather at each shrine for purification rites and prayers before the sacred banners are raised. The atmosphere is solemn, electric with anticipation. Riders begin their march toward the main festival ground at Hibarigahara, a vast open field near the Odaka district.
Day 2 — The Main Event (Honmatsuri, May 23) This is the day everyone comes for. The Hibarigahara field transforms into something between a medieval battlefield and a stadium. The main events:
- Oteyori (Procession): Around 400 horsemen in full armor process through the streets of Minamisoma in a two-kilometer parade that looks ripped from a period drama. Conch shells blow, war drums pound, and samurai banners from dozens of clans stream overhead.
- Kacchu Keiba (Armored Horse Race): The marquee event. Groups of ten riders race around a 1,000-meter dirt track at full gallop, armor clanking, helmets secured by chin cords, dust flying everywhere. There are no jockeys in silk — just warriors in iron and lacquer, riding as their ancestors did. The speed is real, the danger is real, and the crowd noise is deafening.
- Shinki Sodatsusen (Sacred Flag Capture): Immediately after the races, Shinto priests launch sacred flags high into the air using small firework rockets. Hundreds of horsemen scramble to catch the flags as they drift down — a chaotic, thrilling free-for-all that recalls the battlefield scrambles of feudal Japan. Catching a flag is considered a divine blessing.
Day 3 — Wild Horse Capture (Nomakake, May 24) At Odaka Shrine, young men in white robes chase and wrestle unbroken horses into the shrine grounds using nothing but their bare hands. This is the oldest part of the festival, closest to Masakado's original vision, and it is raw. The horses are then offered to the shrine gods. It is quieter than the previous day but deeply atmospheric — the ritual feels ancient in a way that the grander events do not.
Day 4 — Return Ceremony (Okaeri, May 25) The horsemen return to their home shrines in a final procession, and the sacred banners are lowered. A closing ceremony marks the end of another year's Nomaoi.
Getting There
Minamisoma is in the coastal Hamadori region of Fukushima Prefecture, roughly 300 km north of Tokyo.
- Shinkansen + Local Train: Take the Tohoku Shinkansen from Tokyo Station to Sendai (about 1.5 hours), then transfer to the JR Joban Line heading south to Haranomachi Station (about 1 hour). Haranomachi is the closest station to the Hibarigahara festival grounds. Total travel time: approximately 2.5-3 hours.
- By Car: From Tokyo, take the Joban Expressway north. The drive takes about 3.5-4 hours depending on traffic. Temporary parking areas are set up around the festival grounds during the event.
- Festival Shuttle Buses: On the main event day (May 23), shuttle buses typically run between Haranomachi Station and the Hibarigahara grounds.
Tips for Visitors
- Arrive early on Day 2. The armored horse race and flag capture are the highlights, and good viewing spots along the track fill up fast. Gates open early morning; aim to be there by 9 AM.
- Bring sun protection. The Hibarigahara field is wide open with little shade. A hat, sunscreen, and plenty of water are essential in late May.
- Dust is part of the experience. When five hundred horses gallop past, the air fills with dust. Wear clothes you do not mind getting dirty, and consider bringing a bandana or mask.
- Respect the sacred areas. Some events, especially the Nomakake on Day 3, are religious ceremonies. Follow staff instructions and maintain a respectful distance.
- Explore the town. Minamisoma has been rebuilding steadily since 2011. The local shopping streets near Haranomachi Station serve excellent Fukushima cuisine — try the local horse meat sashimi (basashi), a regional specialty that feels especially fitting during Nomaoi.
- Book accommodation early. Hotels in Minamisoma fill up months in advance. Sendai (one hour north by train) is a practical alternative with far more hotel options.
Why Soma Nomaoi Matters
Japan has no shortage of festivals, but Soma Nomaoi occupies a category of its own. It is not a reconstruction or a reenactment — the families who ride today are the direct descendants of the samurai who rode centuries ago. The armor they wear is often genuine heirloom equipment passed down through generations. The horses are trained year-round. The pride is personal and familial in a way that few other festivals can claim.
And since 2011, Soma Nomaoi carries an additional weight. The festival grounds sit in a region that was devastated by the earthquake, tsunami, and nuclear disaster. Many riders lost their homes, their horses, their livelihoods. That they rebuilt and ride on is not just tradition — it is a statement.
Whether you come for the spectacle of armored cavalry charging across an open plain or the quieter power of a community that refused to let a thousand-year tradition die, Soma Nomaoi delivers something you will not find anywhere else in the world.
