Hitachiotsu's Ship Festival

A Festival Born from the Sea

Ōtsu sits at the northernmost edge of Ibaraki Prefecture, where steep wooded hills tumble down to the Pacific. Throughout the Edo period this was one of the most important fishing villages in the Mito domain — first famous for pole-and-line bonito fishing, later for sardine purse-seine netting — and it remains one of Ibaraki's leading fishing ports today. Watching over the town from the hill of Karakai-yama is Sawawachigi Shrine (佐波波地祇神社), founded around the year 856 and revered for more than twelve centuries as the guardian of safe passage at sea. So central was the shrine to navigation that the great pine trees once standing on its grounds served as visual landmarks by which fishermen out on the open ocean could fix their position relative to the shore.

The earliest written record of the boat festival appears on a votive plaque written in 1726, the eleventh year of Kyōhō, by a Confucian scholar of the Mito domain. At that time the festival was a true seaborne procession — the deity was carried in a boat across the bay itself. Over the centuries, however, the harbour was reclaimed and the shoreline pushed back, until what had once been open water became dry land. Rather than abandon the route or alter the meaning of the rite, the people of Ōtsu adapted: they kept the same path, but began hauling the boat overland, applying the same techniques their ancestors had used to pull fishing vessels up onto the beach.

Why This Festival Was Designated a National Cultural Property

For nearly fifty years the boat festival climbed a ladder of official recognition, step by careful step. It was named a Prefectural Intangible Folk Cultural Property of Ibaraki in 1975, then a National Selected Intangible Folk Cultural Property in 1979, and finally elevated to a National Important Intangible Folk Cultural Property on 3 March 2017. The Agency for Cultural Affairs justified this highest designation on the grounds that the festival is a representative and typical example of the foundational cultural lifestyle of the Japanese people.

Several features make the festival genuinely unique. It is the only event in Japan in which a working-style fishing boat carrying a deity is processed entirely on land. The hauling technique itself — sliding a five-tonne hull across hundreds of small wooden frames called soroban while violently rocking it side to side — directly preserves a now-vanished method by which fishing boats were once dragged onto the shore. The accompanying boat songs, festival music, ritual roles passed down within specific local families, and the rotational system in which three town districts take turns serving as host together form an integrated cultural complex of remarkable depth, transmitted across generations within the community itself.

Highlights to Look Out For

Visiting the Festival

The festival is held on 2 and 3 May once every five years. The 2 May evening festival, or yoimatsuri, runs from early afternoon into the evening, with the empty boat processed from the port toward the western edge of town. The 3 May main festival, or honmatsuri, is the day to aim for: this is when the portable shrine is loaded onto the boat and the spectacular hauling procession through Ōtsu takes place, beginning around midday and continuing late into the afternoon. Following the 2024 celebration, the next regular festival is scheduled for 2029.

The town becomes very crowded on festival days, and the Kitaibaraki Chamber of Commerce has in recent years offered reserved viewing seats. Free shuttle buses and temporary parking are arranged by the city; please check the Kitaibaraki City Tourism Association website closer to the date for the latest details. If you are travelling from Tokyo, the JR Jōban Line limited express services to Ōtsu-kō Station make this an entirely feasible day trip, though staying overnight at one of the seaside inns of nearby Izura allows for a much more relaxed visit.

What to See Nearby

Even outside the festival years, Ōtsu and the surrounding Izura coastline reward a visit. Sawawachigi Shrine itself, perched on the wooded hill of Karakai-yama, offers fine views down to the harbour and houses the portable shrine that takes centre stage in the festival. A short distance to the east lies the famous Rokkakudō, the small red hexagonal study built in 1905 by the modern art critic and educator Okakura Tenshin on the cliffs of the Izura coast — destroyed by the 2011 tsunami and faithfully rebuilt the following year. The same area includes Tenshin's old residence, the Ibaraki Prefectural Tenshin Memorial Museum of Art, and the dramatic five-cove coastline known as the "Matsushima of Kanto." A little further inland, the broader Kitaibaraki area is renowned for its anglerfish (ankō) hot pot in winter and for fresh seafood year-round.
