It's said that the origins of the word "Oneri" date back to the time when people would pick up their children at the Anzai riverbank and build a parade of floats and stalls, accompanied by "Kiyari", "Ohayashi" accompaniment and local dancers, on their way to dedicate Takyoji Temple "Chigo Mai Gaku" to Sengen Shrine, to pray for peace and good harvest.

It is said that Hikosaka Kyubei, the town magistrate of Sunpu, at the request of the great lord Tokugawa Ieyasu, ordered the town officials and citizens to build floats and floats, and welcomed the group of children at Takyo-guchi in Anzai 5-chome.

At that time, each town would have their own fancy dress parade, which is where the term "Oneri" originated.

The origin of this float is said to be "Idashi", a sign of inviting gods by standing a cedar.
In addition to the cedar, the floats are decorated with pine trees, spears, dolls, and wheels.

As a substitute for Kagura (Shinto music), they play musical accompaniment and parade through the city to pray for peace.

The origin of the floats is believed to be the Yamahoko floats of the Gion Festival in Kyoto, and various forms can be seen all over Japan.
The floats in Sunpu are Edo-style floats that were brought from Edo (now Tokyo), and the dolls sucked into the single pillar are paper substitutes for the gods.
The floats carrying these sacred objects are as sacred as the shrine itself.

In those days, floats and yatai floats were brought out from 96 towns in Sunpu and were carried out into the city of Sunpu until the evening, making it the biggest festival in the Tokai region.

After a few interruptions, it was re-established in 1894, but due to the war between Japan and Russia, the duty station was re-established in 1950.
Currently, five floats and portable shrines, "Jinmu-guruma", "Inari-guruma", "Konohana-guruma" and "Sakuya-guruma", are parading through the city.
