Jissaiji Sanmon

The Gate at the Southeast Corner

Jissaiji Sanmon (実際寺山門, also written Jissai-ji Sanmon), the main gate of the Koyasan Shingon temple Jissaiji in the Nakashima district of Kurashiki, Okayama Prefecture, is a timber yakuimon gate dated by the Agency for Cultural Affairs to 1884, and it entered Japan's national register of Tangible Cultural Properties on 5 December 2019.

The gate stands at the southeast of the precinct and faces south. Its opening measures 2.6 metres, and short earthen sleeve walls run off it to left and right, tiled in hongawara like the gate itself. A yakuimon carries two main posts set toward the front and two lighter rear posts, with the ridge sitting off-centre above them. It is a form that reads as substantial without the four-post symmetry and elaborate ornament of a gate at a great monastery.

The record leaves one question open. The Agency's date field gives 1884, the seventeenth year of Meiji, while the descriptive note in the same record calls it a weighty gate reaching back into the late Edo period. The two statements have not been reconciled in the published sources. Reused timber is one plausible explanation, since the bell tower in the same precinct is explicitly described as built from re-employed early modern members, though nothing in the record confirms this for the gate. A visitor is safest treating 1884 as the year the gate took its present form.

Carpentry Worth Naming

The official description of this gate is unusually specific about joinery, and the terms repay a little unpacking.

The main posts are gohira, cut to a flattened rectangular section rather than a square one, which gives the gate a broad face when seen from the approach and a slimmer profile from the side. Across their heads runs the kabuki, the tie beam that gives this whole family of gates its structural logic. Above that the carpenter set a menbari and an obari, the lighter and heavier of a paired beam system, and carried the purlin and beam on demitsudo brackets, a three-block bracket set projecting forward from the post head.

At the gable ends sit a koryo, a beam given a gentle rainbow curve, and a kaerumata, the frog-leg strut whose splayed silhouette fills the triangle beneath the ridge. Below the ridge purlin the carpenter added kobana, small fist-shaped nose carvings at the beam ends. The eaves use hitonoki mabara-daruki, a single tier of rafters spaced widely apart rather than the dense parallel ranks of a high-status hall.

Taken together these choices describe a builder working carefully within limited means. The bracket sets and the carved noses are the vocabulary of formal temple architecture. The single sparse rafter tier and the modest 2.6-metre opening are the vocabulary of a village temple. Registration number 33-0334 was granted under the criterion that the structure contributes to the historic landscape of the country, which is exactly what a gate of this kind does.

Reading the Precinct From Its Threshold

Kurashiki City describes Jissaiji as sitting at the centre of the old village of Nakashima on a square plot built up with stone retaining walls. The gate is where that description becomes physical. Approach from the south and the ground rises slightly, the stone embankment carries the earthen wall along the eastern edge, and the tiled ridge of the sleeve walls draws the eye toward the opening.

Six structures at Jissaiji went onto the register together in December 2019, and five of them are visible from the gateway or a few steps inside it: the main hall of 1649 across the gravel to the west, the bell tower of 1879 close by to the northeast of the hall, the thatched guest hall beyond it, the two-story storehouse against the eastern edge, and the outer wall and stone embankment running 61 and 71 metres around the site. Standing in the gate opening is the single best position for understanding why the whole precinct was registered rather than any one building.

The sleeve walls deserve a moment. The outer wall registered as a separate property begins at the northeast corner of the storehouse, runs north, turns west at the corner, and drops to a lower tiled tsuiji wall along the northern edge. The stone below it is laid in irregular rangumi coursing on the east face and in diagonal tanizumi along the north. Different techniques, one enclosure, built up over the middle Meiji years.

Practical notes. Jissaiji is a working parish temple with a cemetery, not a sightseeing temple, and no admission is charged or arranged. The gate stands on the public approach and can be seen and photographed from outside at any hour. Walking into the precinct during daylight is generally accepted, and a word at the temple office first is the courteous course, particularly if you plan to photograph. The guest hall interior is closed. Nishi-Achi Station on the JR Sanyo Main Line, one stop west of Kurashiki, lies about 600 metres away, roughly a ten-minute walk east through a residential district.
