What Jokoji Temple Main Hall Is
Jokoji Temple Main Hall is the principal worship hall of a Pure Land Buddhist temple on Iwagi Island in Kamijima, Ehime Prefecture, built in 1752 and listed as a Registered Tangible Cultural Property on January 8, 2009. In Japanese it is 浄光寺本堂 (Jōkō-ji Hondō), and it is a small building by any measure: three bays across the front, with a floor area of 95 square meters.
The hall faces south. Its roof is Hōgyō-zukuri, a pyramid whose four hip ridges rise to meet at a single point, and it is covered in Hongawarabuki tiling. A one-bay Kōhai canopy projects over the front steps. At the rear, a lower Geya lean-to extends the plan backwards, so that walking around the building you see the roof drop a level and continue.
Repairs were carried out in 1825, roughly seventy years after construction.
Jokoji is a working parish temple in the Pure Land Buddhism tradition, maintained by its congregation. A separate Jizo hall of 1831 stands immediately to the east. The Agency for Cultural Affairs describes the building as an example of a small-scale Jodo sect main hall.
Why It Was Registered
The registration criterion applied to Jokoji Temple Main Hall is that the building serves as a model of design. Its registration number is 38-0087, from the 62nd round of listings, and the notice appeared in the official gazette on January 22, 2009.
What earned that assessment sits in the details rather than the outline. The pillars are square in section with the arms chamfered off, a treatment called mentori hobashira. Above each pillar sits a large bearing block, or daito, finished with a kibana nose carving that projects outward. From the block springs a bracket arm whose profile has been cut into a curve, the type known as eyo hijiki, and it is this arm that carries the purlin. In the space between pillars, where a bracket complex would sit on a larger building, the carpenters placed minozuka struts, named for their resemblance to a straw rain cape.
The eaves use a single tier of closely spaced rafters. Only one layer of Taruki projects, but the rafters are set tight against one another. Doubling the eaves was the expensive option; packing a single tier densely was how a modest hall gained visual weight at the eaves line without it.
So the carving is generous and the plan is not. Three bays, no more. Reading Jokoji Temple Main Hall is largely a matter of seeing where an island temple of the mid-Edo period chose to spend and where it chose not to.
What to Look For
The carving under the front canopy
Stand at the front and your eye goes first to the underside of the kohai. The spiral of the kibana, the curve cut into the bracket arm, the notching of the minozuka: none of it is monumental, but all of it sits within a few meters of your head, so the individual chisel lines are legible. Step to one side and the depth of the relief becomes much easier to judge than it is head-on.
The pyramid roof, seen off-axis
Viewed straight from the front, a hogyo-zukuri roof reads as a plain triangle. Move around to a corner and the geometry opens up: four hip ridges, each foreshortened differently, converging at one point overhead. The rounded tiles of the hongawarabuki covering throw stripes across the slope that darken or flatten depending on where the sun is.
The division between outer and inner sanctuary
Inside, the front two bays form the gejin, the outer worship space, and the area behind it is the Naijin, the inner sanctuary, with a Shumidan altar platform set slightly back of center. It is the simplest possible arrangement, a three-bay box cut in two front to back, but it separates where worshippers stand from where the main image is enshrined. The interior is not open on a regular basis, so from outside you infer the division from the placement of the doors along the front.
The Jizo hall next door
East of Jokoji Temple Main Hall stands the temple's Jizo hall, built in 1831 and also facing south. It covers 16 square meters and is roofed in the Irimoya-zukuri hip-and-gable form. Having a pyramid roof and a hip-and-gable roof side by side, at a scale you can take in from one spot, makes the comparison unusually easy.
Visiting Jokoji Temple Main Hall
Jokoji is in daily use by its parishioners. Neither the Kamijima town website nor the town tourism site publishes opening hours or an admission fee for the hall. You can see the exterior from within the temple grounds; if you want to go inside, contact the temple beforehand. Services are held here, and you may arrive during one.
For photography, follow any notices posted in the grounds and any instruction from the temple. Even when shooting only the exterior, take care to keep the cemetery and any mourners out of frame. Setting up a tripod is something to ask about first.
The address is 855 Iwagi, Kamijima-cho, Ochi-gun, Ehime Prefecture, in the village a 7-minute walk from Iwagi Port. Geiyo Kisen runs passenger boats to that port from Imabari on Shikoku, carrying foot passengers and bicycles only. Drivers have a shorter option: the Sanko Kisen ferry from Sunoe Port on Ikuchijima, in Onomichi, Hiroshima Prefecture, across to Okogi Port on Iwagi Island.
Coming off the Shimanami Kaido, take the Ikina Ferry from Hansenbashi at Habu Port on Innoshima to Tateishi Port on Ikinajima, then cross the Iwagi Bridge, which opened on March 20, 2022. That bridge completed a road link joining Yugeshima, Sashima, Ikinajima and Iwagijima, four islands in all. Cyclists can use it too.
