Long before dawn breaks over Uwajima Bay, you can hear it: the rhythmic pounding of taiko drums echoing off the tile-roofed streets of this compact castle town tucked into the folds of Shikoku’s southwestern coast. By the time the sun clears the mountains of Ehime Prefecture, enormous bamboo-framed beasts with snarling ox heads and shaggy red-cloth bodies are already prowling the narrow lanes, hoisted aloft by teams of sweating young men. This is the Uwajima Ushioni Matsuri — the Bull-Demon Festival — and in 2026 it celebrates its 60th year as one of the wildest, least-touristed summer festivals in all of Japan.
The Legend of the Ushioni
The ushioni (literally “ox demon”) is a creature rooted in the folklore of southern Shikoku. Descriptions vary, but the most common image is a chimera with the horned head of a fearsome bull and the body of a spider or whale, lurking in coastal waters and mountain passes. In Uwajima’s telling, the ushioni was a terror of the region until it was subdued by the deity enshrined at Warei Shrine, the spiritual heart of the city. The festival reenacts this conquest — and celebrates the protective power of the shrine’s god — by parading giant ushioni effigies through every neighborhood before driving them symbolically out of the city.
Three Days of Controlled Chaos
The Ushioni Matsuri runs July 22–24 and is formally part of the Warei Taisai, one of the largest Shinto festivals in Shikoku. Each day builds in intensity.
Day 1 — Opening and Gaiya Dance (July 22): The festival opens with neighborhood ushioni floats gathering in the city center. Some floats stretch over five meters long, their bamboo skeletons draped in palm fiber or red cloth, and crowned with horned wooden heads carved with bared fangs. In the evening, the Gaiya Dance transforms the main streets into an open-air dance floor where thousands of participants in matching happi coats move to a pulsing Uwajima beat. Anyone can join in.
Day 2 — Ushioni Parade and Children’s Events (July 23): The main parade brings over twenty ushioni from neighborhoods across the city together in a slow, swaying procession through the commercial district. The floats lurch and charge at spectators — a tradition meant to ward off evil spirits. Children ride miniature ushioni of their own. Street food stalls line the route: try jakoten (a local fried fish-paste specialty), tai-meshi (sea bream rice served Uwajima-style, raw over hot rice with egg), and kakigori shaved ice.
Day 3 — Hashiri and Fireworks (July 24): The climax. In the Hashiri, teams of young men sprint with heavy mikoshi (portable shrines) down to the banks of the Suka River and plunge them into the water amid a frenzy of chanting and splashing. This purification ritual is the spiritual heart of the festival. That night, fireworks explode over Uwajima Bay, their reflections shimmering across the calm waters of the Uwa Sea.
Warei Shrine: The Festival’s Spiritual Core
Warei Shrine, set at the foot of forested hills overlooking the city, enshrines Yamabe Kiyohiro, a retainer of the Date clan who governed Uwajima Domain during the Edo period. After his unjust death, strange calamities befell the city, and a shrine was built to pacify his spirit. Today Warei Shrine is one of the most important fishermen’s shrines in the region, and the Warei Taisai is both a plea for calm seas and an expression of civic pride.
Beyond the Festival: Uwajima in Summer
Uwajima rewards visitors who linger. The city’s hilltop Uwajima Castle is one of only twelve original-keep castles surviving in Japan — a small but elegant structure with views across the bay. The Taga Shrine, famous for its fertility museum, is one of Japan’s quirkiest cultural detours. The coastline south toward Ainan offers pristine diving and snorkeling in the Ashizuri-Uwakai National Park, and the local seafood — especially Uwajima-style tai-meshi — is reason enough for the journey.
Getting There
Uwajima sits on the JR Yosan Line. From Matsuyama, the limited express takes about 80 minutes. From Osaka or Tokyo, take the Shinkansen to Okayama, transfer to the Shiokaze limited express to Matsuyama, then change to the Uwakai limited express. The total journey from Osaka is roughly five hours, but the scenery through the mountains of western Shikoku makes it worthwhile.
Tips:
- Book accommodation early — Uwajima’s hotel capacity is limited and the festival fills everything.
- The Gaiya Dance on Day 1 is the most participatory event; join a flying team or watch from the curbside izakayas.
- Bring insect repellent and a towel — July in southern Shikoku is hot and humid.
- For the best fireworks viewing, head to the waterfront park near Uwajima Port.
