Korinji Temple Main Hall

What is the Korinji Temple Main Hall?

The Korinji Temple Main Hall (光林寺本堂, Kōrin-ji Hondō) is the worship hall of a Jōdo-shū temple in Shinonoi Komatsubara, Nagano City, built in 1800 and registered as a Tangible Cultural Property on August 6, 2025. It is a single-storey timber building with a footprint of 312 square meters, renovated in 1978.

The hall stands toward the west of the precinct and faces east, so anyone who climbs the approach steps and passes through the main gate meets its porch straight ahead. The roof is a Yosemune-zukuri hip roof, and the Agency for Cultural Affairs records its covering with an unusual phrase: copper sheet laid in the form of thatch. The roof keeps the deep, rounded profile of a thatched roof, but the surface is copper. From a distance the Korinji main hall still reads as a heavy straw-roofed building.

It is the oldest building at Korinji. The main gate (1826), the bell tower (1830) and the sutra repository (1865) all came later, which makes sense of the layout: the largest and earliest structure set the axis the others follow.

Why the Korinji Temple Main Hall was registered

The Korinji Temple Main Hall was registered under the criterion of buildings that serve as a model of their type, as registration number 20-0669. The temple's sutra repository, bell tower and gate had been registered in 2019, nearly six years earlier.

The official description praises both the clarity of the frame and the richness of the ornament. The outer columns are square in section, the inner ring of columns is round, and the two rows are tied together with curved Kōryō tie beams under a coffered Gō-tenjō ceiling. Shifting from square to round posts as you move inward is a long-standing way of marking the more sacred inner zone of a Buddhist hall, and the builders of Korinji followed it with care.

On top of that frame, carvings cover the building inside and out. The phoenix on the entrance porch and the Taiheizuka struts on the interior beams, flanked by ornamental Oigata boards, are singled out as especially large and eye-catching. A well-proportioned standard plan carried out with bold decoration is what made the Korinji hall a model worth registering.

What to look for at the Korinji Temple Main Hall

The phoenix on the porch

Start with the Kōhai, the porch projecting from the center of the east front. Its phoenix carving is one of the two pieces of decoration the Agency picks out by name. Step back a little after passing the gate and you can take in the porch carving and the bulk of the hip roof together in one view.

Square posts outside, round posts inside

Walk along the veranda and you will notice that every outer post is square. If you are given a chance to look inside, compare them with the round posts of the inner ring; on the Korinji Temple Main Hall the change of section marks the line between the outer worship space and the inner sanctuary.

The carved struts above the beams

Above the interior beams stand short struts that carry roof loads. Here they have been turned into showpieces, with large carved boards on either side. Seen against the grid of the coffered ceiling, they set the tone of the interior.

Visiting the Korinji Temple Main Hall

The exterior of the Korinji Temple Main Hall and its porch carving can be seen from the precinct between the gate and the hall. The phoenix is clearest from directly in front; the mass of the roof shows best from a front corner. Directions to the temple are on the Korinji Temple page.

The interior is not routinely open, and no visiting hours or fees are published. To see the coffered ceiling and the carved struts, contact the temple in advance and avoid times when services are held. There is no published photography policy, so ask permission before taking pictures inside.
