What the Arhat Hall Is
Kosanji Temple Arhat Hall is a Buddhist hall of 1939 on the lowest terrace of Kosanji Temple in Setoda, Onomichi, Hiroshima Prefecture, registered as a Tangible Cultural Property in 2003. It runs out on both sides of the Middle Gate as a roofed corridor and holds rows of arhat figures inside.
Each arm is seventeen bays long and one bay deep, gabled and tiled in Hongawarabuki. It is single-storey timber work covering 346 square metres. The outer wall is filled with Renji-mado lattice, the inner wall with plank doors, and the floor is boarded. Overhead the roof is left open as Keshō-yaneura, showing the Kōryō beams and the scissor bracing.
The Agency for Cultural Affairs commentary records the Arhat Hall as the earliest building in the central precinct, from a time when only a handful of structures stood here.
Why It Was Registered
Kosanji Temple Arhat Hall was registered under the criterion for work not easily reproduced. Its model is the cloister of the western precinct at Horyuji, but it does not stop at being a boundary walk: it was given the function of a hall housing five hundred arhats, and that shift is what sets it apart.
The temple describes this as a clear case of the founder's habit of making buildings useful. A cloister need only be walked through; a hall of figures needs depth, a floor built for standing statues, and controlled light. Lattice outside and plank doors inside reads as an answer to that demand.
Five hundred arhat figures are enshrined here, carved, the temple records, by sculptors from Nara with the founder himself taking part. It was registered on 19 September 2003 under number 34-0045.
What to Look For
The Arhat Hall is long. Seventeen bays run east and seventeen west of the Middle Gate, so taking it in from the front is awkward. Stand at one end instead and look along the building: the vertical bars of the lattice turn into perspective lines running away from you.
Look up and the roof is not ceiled. Left as Keshō-yaneura, it shows the Kōryō and the scissor bracing directly, and that open framing gives height to a space that is otherwise narrow and crowded with figures.
Check the pairing of lattice outside and plank doors inside. From the courtyard you catch the dark of the interior through the gaps; from within, the same wall is a closed plane of boards. One wall, two opposite characters depending on where you stand.
The roof is a plain gable, straightforward among halls that mostly reach for hip-and-gable and frontality. Set it beside the two-storey Middle Gate and the difference in ornamental density is immediate.
Visiting the Arhat Hall
The interior of Kosanji Temple Arhat Hall is closed and cannot be entered. Viewing is from the outside, with only glimpses of the interior through the lattice.
There are two useful positions: squarely in front of the Middle Gate, taking in the arms running left and right, and at the east or west end, following the length of the building on the diagonal. The second gives a better sense of the scale. Climbing part way up the steps to the middle terrace brings the run of roof into view from above.
