What taisha-zukuri means
Taisha-zukuri is a form of Shinto main hall with a near-square plan divided into two bays on each side and a gabled roof entered from the gable end, the arrangement called Tsumairi. The name comes from Izumo Taisha, whose main hall is its best-known example. The Agency for Cultural Affairs describes that hall as a square-plan, gabled, gable-entry taisha-zukuri building, and its commentary on the main hall of Kamosu Shrine notes that the form is found only in the old province of Izumo, the eastern half of present Shimane Prefecture. Together with Shinmei-zukuri, it is counted among the shrine forms that predate the influence of Buddhist temple architecture.
A pillar of exceptional thickness stands at the centre of the plan. Called the shin-no-mihashira, it has been treated as sacred since early times, and the interior is divided into front and rear halves along a line running through it. The entrance occupies only one of the two front bays and is reached by a stair. At Izumo the plank door opens in the right-hand bay as seen from the front, while the left-hand bay is closed with a hinged lattice shutter. Inside, the enclosed shrine that houses the deity sits at the right rear and faces left, so the deity does not face the worshipper. That offset between entrance, deity and the axis of the building is the feature that most clearly marks the form.
The floor is raised high and a veranda runs around all four sides. At Izumo the roof is cypress bark with gently curved bargeboards, and crossed Chigi and horizontal Katsuogi ride on the ridge. Shinmei-zukuri also has a gabled roof, but it is entered from the long side, the arrangement called Hirairi, and its roofline is straight. Kasuga-zukuri is entered from the gable end as well, but it is a single-bay hall with a canopy across the front, much smaller and simpler in plan than the two-by-two taisha form.
Reading the records and the building
In the structure line of the national database, taisha-zukuri halls are recorded with the name of the form followed only by the roofing material. Izumo is entered as taisha-zukuri with cypress-bark roofing, and Kamosu as taisha-zukuri with thick wooden shingles. Dimensions and the position of the door do not appear in that line and have to be taken from the detailed commentary or from repair reports.
On site, the useful place to stand is outside the fence, looking at the gable end. A stair set to one side of the gable rather than on its centre line shows the one-sided entrance of the taisha plan. Two bays along the side and two across the front show that the plan is close to square, and the high floor and the veranda on all sides can be seen from outside the enclosure.
Differences within the form are also recorded. The agency's commentary on the Kamosu hall, rebuilt in 1583, observes that it closely resembles Izumo but is slightly longer along the ridge than across it and has thick pillars for its size, and it reads both points as signs of an older version of the form. The Izumo hall, built in 1744, is a square about 10.9 metres on each side and stands about 24 metres from the top of the foundation stones to the tips of the crossed finials. Within the same form, the proportions of the plan and the weight of the pillars change with date.
