What the Uwajima Castle Tower Is
The Uwajima Castle Tower (宇和島城天守, also written Uwajima-jō Tenshu) is a mid-Edo period castle keep at Marunouchi in Uwajima City, Ehime Prefecture, designated an Important Cultural Property on 30 January 1934. It rises three roofed storeys over three floors, is roofed in Hongawarabuki tiling, and stands alone on its stone platform, the walls finished in white plaster laid over every surface. Only twelve keeps in Japan have stood continuously since before the Edo period ended, and the Uwajima Castle Tower is one of them.
The castle occupies a hill about 70 metres high near the middle of modern Uwajima. Todo Takatora built the first castle here, and a keep stood on the site by around 1601. That earlier building sat directly on the natural bedrock and looked nothing like the present one. According to Uwajima City, the current keep came out of a major overhaul by Date Munetoshi, the second lord of the Date house here: Takatora's tower was removed, a stone platform was built, and a new keep went up in the tower type then in fashion.
The completion date is still open. The Agency for Cultural Affairs database dates it to 1664 to 1665. Uwajima City puts it at around 1666, and in June 2026 the city stated publicly that no document fixes the year and that the question is still being worked through from various sources. The fact that the number has not settled is itself a sign that research on this building is live.
Why It Is an Important Cultural Property
What makes the keep matter is what was left out of it. There are no Sama loopholes for guns or arrows, and no Ishiotoshi chutes for dropping stones on anyone at the base. Instead the interior carries Nageshi tie-rails and fitted sliding doors. The finish belongs to a formal residence rather than to a fortification, which is the point: by this date a lord's keep was there to be looked at.
The exterior states this even more plainly. A large Noki-karahafu, an undulating gable set into the eaves, crowns the top roof. Below it sits a large Chidori-hafu dormer gable, and below that a pair of smaller ones. Gegyo pendants hang beneath the gable peaks. At ground level a formal entrance porch projects forward under its own curved gable. Against the white walls the gables stack in staggered tiers, a composition the city reads as an emblem of a country at peace.
Uwajima City gives the height as 15.72 metres, measured from the foundation stones to the main ridge, and the eave area of the first floor as 212.75 square metres. The first storey is six Ken square, the second five and the third four, each stage narrowing by the same ratio so that the whole reads as a tapering tower. The Ehime Prefectural Board of Education gives the height as 14.5 metres instead; the two figures have not been reconciled.
A major repair followed in 1860, and a full dismantling repair ran from 1960 and finished in October 1962. A one-tenth scale model of the keep, made for the 1860 work, still survives. Having both the building and its Edo period model is rare.
What to Look At
Once you are up the hill, stand square in front of the building. The four tiers of gables only resolve from below; that is the angle the design was drawn for. The formal porch with its raised entrance step was built to receive callers, not to be barred in a siege.
Inside, watch your feet and your eye line. A corridor a bay and a half wide runs around the first floor, and slotted warrior windows open in the walls. Tie-rails run at head height, with grooves for doors above and below. The timber has aged and been polished by handling, and wear in the floorboards shows where people have walked.
From the third floor the windows open onto Uwajima Bay. This is where the geography clicks into place: the castle sits at the innermost point of a deeply indented ria coastline, and you have to be at this height to see why that mattered. The inner wall of the top floor keeps its rack for arms and a smoke vent window.
Back outside, look at the stonework of the platform. Because the Uwajima Castle Tower replaced a keep that had stood on bare rock, the relationship between this masonry and the building above it is the physical record of the rebuilding.
Visiting
The keep is open 9:00 a.m. to 4:00 p.m. from November to February and 9:00 a.m. to 5:00 p.m. from March to October, every day of the year. Admission is 200 yen for adults, free for high school students and younger, and 160 yen for visitors aged 65 and over and for groups of 20 or more. Payment is cash only, on the day. The castle hill itself is free, open 6:00 a.m. to 5:00 p.m. from November to February and 6:00 a.m. to 6:30 p.m. from March to October. The keep is floodlit from sunset until 10:00 p.m.
Personal photography is not restricted. Commercial shooting for publications or film needs advance permission, and because the hill is also a city park the application goes to the municipal urban development section. Smoking is banned across the hill, and pets may not be taken into the keep or the local history museum, guide dogs excepted. The city also asks visitors not to mark or damage the stonework and the building.
From JR Uwajima Station it is about 15 minutes on foot, roughly one kilometre, to the foot of the hill; allow around 35 minutes from the station to the keep itself, since the last stretch climbs. By car it is about one kilometre, or four minutes, from the Uwajima Asahi interchange. The car park below the hill is open 24 hours at 100 yen per hour and holds 46 standard vehicles.
Approach routes change. The southern path on the Noboritachi Gate side was closed in July 2026, and from 1 August 2026 the section running from that gate to the local history museum reopened on a provisional basis. The stretch continuing to the children's park remains closed, as checked on 4 September 2026. The castle also closes at short notice in typhoons and heavy weather, so check the city's notices before setting out.
