Held every year from August 24 to 26 in Shinjo City, Yamagata Prefecture, the Shinjo Festival is one of the Tohoku region’s most celebrated summer festivals. With a history spanning more than 260 years, the festival fills the city with magnificent floats, traditional music, processions, and performing arts.
The festival’s greatest attraction is its collection of 20 elaborately decorated floats, known as yatai, created by different neighborhoods. Inspired by historical stories, legends, Kabuki, Noh theater, and traditional folktales, each float combines buildings, mountains, waterfalls, flowers, waves, trees, and figures to create a unique three-dimensional scene.
The festival also features a mikoshi procession involving around 200 people dressed as samurai, Shinto priests, and other historical figures, as well as the traditional Hagino Shishi Odori and Nitayama Shishi Odori, dances performed to pray for abundant harvests. For three days, Shinjo becomes filled with the sounds of festival music and the excitement of the crowds, creating a vivid atmosphere reminiscent of an Edo-period castle town.
The Shinjo Festival is believed to have begun in 1756, during the Edo period. The previous year, a severe famine had caused great hardship throughout the Shinjo domain. In response, the domain lord Tozawa Masanobu organized a grand festival at Tenmangu Shrine, bringing the people together to restore their spirits and pray for a successful harvest.
Over the following decades, the festival gradually grew in scale. Historical records from 1776 already mention floats, suggesting that processions featuring decorative displays and hanagasa hoko floats, decorated with traditional flower hats, were already taking place at that time.
In 2009, the Shinjo Festival Float Event was designated as an Important Intangible Folk Cultural Property of Japan. In 2016, it was included among the “Yama, Hoko, Yatai, Float Festivals” inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity. The designation recognizes the cultural traditions that have been carefully passed down through generations by the local community.
The symbols of the Shinjo Festival are the 20 magnificent floats created by local neighborhood groups known as wakaren. These groups are made up of people from each community who take responsibility for preparing and operating their float. Rather than relying entirely on professional craftsmen, local residents work together, often fitting float construction around their regular jobs and daily lives.
Planning begins well before the festival. As August approaches, members gather at temporary float workshops, where construction becomes increasingly intensive. Every part of a float is carefully designed, from scenery such as buildings, mountains, waterfalls, waves, cherry trees, and pine trees to the figures, costumes, and props representing characters and animals.
The themes vary from float to float. Historical figures and stories, Kabuki and Noh plays, legends, and traditional tales all serve as sources of inspiration. Because each neighborhood develops its own concept and works on its float throughout the year, visitors can look forward to seeing completely different scenes every year.
In the weeks leading up to the festival, members of the wakaren may work on their floats from early morning until late at night. Their desire to complete an impressive float is shared not only by adults but also by the children who help pull the floats through the city.
This tradition of passing knowledge and enthusiasm from parents to children and from one generation to the next is one of the Shinjo Festival’s greatest cultural treasures. The festival is not simply a tourist attraction; it is a community event in which people of different generations participate together.
The floats are enormous structures, measuring approximately 3 meters wide, 8 meters long, and 4.7 meters high. Their left sides are generally decorated with elaborate scenes, while mountains and other elements are arranged on the right to create a balanced overall composition.
At the front of each float is a steering beam, or kajibo, to which two long ropes are attached. On the festival days, numerous people, including children, work together to pull the heavy floats through the streets.
Another important role is that of the people responsible for raising the overhead wires. They carry long poles to check the height of the floats and help prevent them from catching on electrical wires and other obstacles. Watching a float move through the city also offers a glimpse of the careful teamwork and practical techniques that make the procession possible.
The magnificent floats are accompanied by the lively sounds of Shinjo Hayashi, the traditional festival music of Shinjo. Its main instruments include the flute, kane bell, large taiko drum, small taiko drum, and shamisen, performed by specialized festival music groups known as hayashi wakaren.
Pieces such as Shuku-watari and Kakko are commonly performed, but their detailed melodies and playing styles can vary from one neighborhood and hayashi group to another. Because the music has traditionally been passed down orally rather than through written scores, each community has developed its own distinctive style.
In the weeks before the festival, the sound of rehearsals can often be heard throughout Shinjo in the evenings. The city gradually begins to feel the approach of the festival even before the floats appear on the streets.
The first day is known as Yoimatsuri, or the evening festival. All 20 floats travel through the city, departing from their respective neighborhoods and making their way toward the area around Shinjo Station.
The streets come alive with the sounds of festival music, calls from the participants, and the movement of the enormous floats. As darkness falls, lights are switched on and the appearance of the floats changes dramatically.
The illuminated figures, buildings, and decorations emerge from the darkness, creating an almost dreamlike atmosphere. The magnificent floats seem to transform into moving historical picture scrolls, bringing legendary scenes and traditional stories to life.
At Abies, the Fureai Hiroba plaza in front of Shinjo Station, visitors may also have an opportunity to see all 20 floats gathered together. It is an ideal setting for those who want to take their time examining the intricate details at close range.
The second day is the Honmatsuri, or main festival, featuring a grand mikoshi procession that evokes the history of Shinjo as an Edo-period castle town.
The procession begins at Tozawa Shrine, located at the site of Shinjo Castle. Around 200 people, including participants dressed as samurai and Shinto priests, take part in the procession.
Wearing costumes inspired by the period of the Shinjo Domain, the participants walk through the city in a scene that can feel as though an Edo-period castle town has suddenly returned to life.
The 20 floats follow the mikoshi procession through the streets. In the daytime, the floats are brightly illuminated by natural sunlight, revealing colors and details that can be difficult to see at night. The happi coats worn by the wakaren members, energetic calls from the participants, and lively festival music add to the excitement.
The final day, known as Atomatsuri, features two traditional dances that have been passed down for generations in the northern part of Shinjo City: Hagino Shishi Odori and Nitayama Shishi Odori.
These shishi odori, or traditional deer dances, are performed as prayers for abundant harvests and other blessings. Dancers dressed in colorful costumes perform rhythmic movements to distinctive traditional music. Performances offered at places such as the former Shinjo Castle site provide a different perspective on Shinjo’s traditional culture from the spectacular floats.
The floats are also displayed as decorative exhibition floats, allowing visitors to examine them more leisurely. Seeing all 20 floats assembled together creates an impressive sight and provides a fitting finale to the three-day festival.
The appeal of the Shinjo Festival goes far beyond its magnificent floats and large-scale processions. The festival is supported by people of many generations, including the wakaren who build the floats, the hayashi wakaren who perform the music, and the children and adults who pull the floats through the streets.
During the festival season, many people who originally come from Shinjo and the wider Mogami region but now live elsewhere also return to their hometowns. For local residents and former residents alike, the festival has a special meaning as an opportunity to reconnect with their community and traditions.
Although the festival has changed in various ways over its long history, adapting to different eras while preserving its essential traditions, the commitment of the people who support it has continued from generation to generation.
Today, the three days of the Shinjo Festival remain a defining symbol of summer in Shinjo, bringing together history, traditional performing arts, music, craftsmanship, and community spirit.
One of the best ways to experience the Shinjo Festival is to see the floats both during the day and at night. In daylight, visitors can closely appreciate the intricate figures, miniature buildings, costumes, scenery, and vivid decorations. After dark, the illuminated floats take on an entirely different and more fantastical appearance.
It is also worth looking beyond the floats themselves. The mikoshi procession, shishi odori dances, and Shinjo Hayashi each represent different aspects of the region’s traditional culture. Experiencing all of them helps visitors understand the Shinjo Festival not simply as a spectacular parade, but as a living cultural tradition shaped by the local community.
The Shinjo Festival brings together history, tradition, craftsmanship, music, and the enthusiasm of local residents. The sight of 20 magnificent floats filling the streets is unforgettable, but the festival is equally fascinating for the dedication of the people who spend months preparing for it and the traditional music that echoes through the city.
For anyone visiting Yamagata in late August, the Shinjo Festival offers a memorable opportunity to experience the energy and cultural heritage of northern Japan at its most vibrant.
