Shinjo Festival Floats and Shinjo Castle Ruins: Shonai Festival Counted Among Tohoku's Three Great Festivals

The "Shinjo Festival," held every year from August 24 to 26 in Shinjo City, Yamagata Prefecture, is a traditional festival inscribed on the UNESCO Intangible Cultural Heritage list and designated a National Important Intangible Folk Cultural Property. The sight of gorgeous floats (yatai) themed on historical picture scrolls and stories parading through the former castle town to the accompaniment of flute and drum hayashi music is overwhelming. Boasting some 260 years of history, it continues to fascinate great numbers of people as a major event that colours summer in Shinjo.

History of the Shinjo Festival

The Shinjo Festival is said to have begun in 1756, in the middle of the Edo period. Its origin lies in the encouragement given by the lord of the Shinjo domain, the Tozawa clan, to the festivals of the shrines in the castle town, in order to raise the spirits of domain residents suffering from a disastrous crop failure the previous year and to pray for an abundant harvest. Since then it has been handed down as a festival of the whole town, and in recognition of its rich float-festival culture it was inscribed in 2016 on the UNESCO Intangible Cultural Heritage list as one of Japan's Yama, Hoko and Yatai float festivals. It is a festival representative of Tohoku, imbued with a long history and the wishes of its people.

Gorgeous, Magnificent Floats

The greatest highlight of the Shinjo Festival is the splendid floats that each neighbourhood spends a full year building. Themed on kabuki, historical tales and legends and brilliantly decorated with figures and ornaments, the floats are truly moving works of art. Because they are rebuilt anew every year, each year's designs are unique. At night the lanterns are lit and they show a fantastical face quite different from the daytime. The scene of the yoi-matsuri (eve festival), as they parade through the castle town to the sound of the hayashi music, sets the hearts of onlookers racing.

Together with the Shinjo Castle Ruins

Shinjo, the stage for the festival, has a history of prospering as the castle town of the Tozawa clan's 60,000-koku domain. In the city, the Shinjo Castle ruins have been laid out as "Mogami Park," where the moats and stone walls convey the appearance of former days. Within the park there is a shrine dedicated to the Tozawa clan, and it is also loved as a cherry-blossom spot. Even outside the festival period, it is a place where you can feel the atmosphere and history of a castle town. Touring the castle ruins along with the Shinjo Festival lets you appreciate more deeply the town's path through history and the feelings people have invested in the festival.

Best Season and Access

The Shinjo Festival is held every year from August 24 to 26. The greatest highlights are the yoi-matsuri, when all the floats line up, and the procession of the main festival. For access, the venue is within walking distance of Shinjo Station on the JR Yamagata Shinkansen, about three and a half hours from Tokyo by Shinkansen. The festival period is crowded with spectators, so planning early is recommended. Come and experience at close range the heat of a festival representative of the Tohoku summer, woven from magnificent floats and spirited hayashi music.
