Every spring, thirteen tall floats with mechanical puppets roll through Inuyama's historic streets beside the castle, and this guide covers the history, the highlights and how to plan a visit.

Quick answer: The Inuyama Festival is the spring festival of Haritsuna Shrine in Inuyama, Aichi Prefecture, and it is usually held on the first Saturday and Sunday of April, with organizers setting the exact days each year. Thirteen three-tiered floats called yama carry karakuri puppets by day and glow with hundreds of paper lanterns by night. It is one of the 33 float festivals on UNESCO's list of intangible cultural heritage.

What the Inuyama Festival Is

The Inuyama Festival is a two-day spring celebration in the castle town of Inuyama, in the northern part of Aichi Prefecture. It is the main yearly ritual of Haritsuna Shrine, and the whole town takes part. Thirteen decorated floats, each belonging to a different neighborhood, are pulled through the narrow streets of the old merchant quarter while flutes and drums keep time. The setting is part of the charm. Inuyama Castle stands above the town, and the festival usually falls during cherry blossom season, so the streets are often framed by pale pink petals.

Local people use the word yama for the floats, a term that is also found in other float festivals across Japan, while many nearby Owari-region towns say dashi. Each float is a miniature stage on wheels, and each neighborhood looks after its own. Residents of all ages help prepare, from the people who handle the ropes to the musicians who play from inside the floats, and the festival is a good example of how a community passes skills from one generation to the next.

The prefectural tourism guide describes the event as the only festival in Japan where doll joruri and karakuri puppet performances are given from the top of floats. Whether or not a visitor knows anything about mechanical puppets in advance, the sight of a small wooden figure moving on an upper stage while a big wheeled float turns a street corner is memorable.

History and Origins

According to local tourism sources, the festival began in 1635, in the early Edo period, as an offering to the deity enshrined at Haritsuna Shrine. A Nagoya-area guide counted the 2025 festival as the 391st edition. Early forms of the celebration are said to have included a decorated horse and a procession of tea pickers, and over the centuries it grew into the float parade known today.

Haritsuna Shrine is the heart of the event. The floats gather in the plaza in front of Inuyama Castle, which links the festival to the old castle town and to the people who lived and traded in it. The tradition was recognized by Japan as an important intangible folk cultural property, and in 2016 it was inscribed by UNESCO together with other float festivals from across the country.

The floats themselves have been handed down for generations. The prefecture has designated all thirteen as tangible folk cultural properties, which means the wooden structures, carvings and decorations are treated as treasures to be repaired and protected, not simply replaced.

The Thirteen Floats

Each float follows a three-tiered design. According to tourism sources, the floats are around eight meters tall and weigh several tons, which is why it takes teams of neighborhood residents to guide them. The puppets perform from the upper part of the float, with flute and drum music accompanying them, while the base holds the wheels that the pulling teams guide through the streets.

The thirteen floats parade through the castle town, and each one represents a neighborhood with its own character. Looking at the details up close, for example the carvings, the curtains and how the lanterns are arranged on the frame, is one of the most enjoyable parts of a visit.

At night the floats are redecorated with paper lanterns. The prefectural guide says each float is hung with 365 lanterns, a number that matches the days of the year, and the combined glow of all thirteen is often described as dreamy. The same floats that look elegant in daylight take on a very different feeling after dark, so many visitors plan to see both.

What Happens During the Festival

The festival is held over a Saturday and a Sunday. Local guides describe the first day as a rehearsal day and the second as the main festival, although both days include parades through the castle town. During the day, the floats move through the streets and stop at set points where the karakuri puppets perform to the sound of flutes and drums.

In the evening, the lantern parade begins. A Nagoya-area guide listed the 2025 evening parades as running from about 18:00 to 22:00, with the floats moving in two groups on the main day. Schedules can change, so the festival's official site and the Inuyama tourist information center are the best places to confirm times.

The festival can be affected by rain, and organizers decide each year whether to adjust the program. Visitors who plan the trip with a flexible mindset, and who check the weather the day before, are the most likely to enjoy it fully.

Karakuri, Music and the Famous Donden

The karakuri are mechanical puppets that move in time with the flutes and drums played on each float. Their carefully timed movements are worked from within the float, and the performances have long been a showpiece of the festival. The tradition goes back to the Edo period, and the performances are one of the reasons the festival is so highly regarded.

The most exciting moment for many spectators is the donden. This is a maneuver in which a team lifts the front of a heavy float and swings it around to change direction, instead of turning it with a wide curve. The prefectural guide describes a float of several tons being hoisted and suddenly rotated, and the crowd usually responds with cheers. A related technique, a sliding turn at corners, sends the wheels screeching on the road as the float is pushed sideways.

The donden is best watched from a safe distance behind any barriers, and visitors should follow the instructions of the staff and the local teams. The movements look dramatic, and the teams work hard to keep everyone safe.

Planning Your Visit

Inuyama is easy to reach from Nagoya. A private railway line runs from central Nagoya to Inuyama Station in roughly 25 to 30 minutes, according to a local guide. From the station, the castle town is about a 15 to 20 minute walk, and the route toward the castle passes shops and the shrine area. The prefectural guide lists Inuyama Yuen Station as another access point, with about a 15 minute walk to the castle plaza.

Parking near the town is limited, so public transportation is strongly recommended on festival days. Crowds are large, especially in the evening, so arriving early in the afternoon gives a better chance of finding a good spot along the route. Comfortable walking shoes are helpful, as the streets are narrow and the day is long.

Etiquette is simple. Please keep a respectful distance from the floats, avoid touching the decorations, stay behind ropes and staff lines, and be careful with umbrellas, tripods and bags near the pulling teams. A friendly, patient attitude goes a long way in a crowd.

Food, the Castle Town and the UNESCO Listing

The best way to spend the spare hours around the parade is to explore the castle town itself. The old streets near the shrine and castle have small shops and places to rest, and the cherry trees nearby add to the seasonal feeling. Visitors often combine the festival with a walk to Inuyama Castle, since the castle plaza is the festival's main gathering place.

In 2016, UNESCO added the Yama, Hoko, Yatai float festivals of Japan to its list of intangible cultural heritage, a group that began with 33 festivals spread from northern Honshu to Kyushu. The Inuyama Festival is one of the Aichi Prefecture entries. UNESCO describes these festivals as ways for communities to pray for peace and protection from disasters, and as occasions where people of different ages share responsibility for making and caring for the floats.

Because the festival is a living tradition, the best preparation is to check the official schedule shortly before traveling, and to arrive with time to enjoy the town, not only the parade.
