Korinji Temple

Korinji Temple: a Jodo-shu temple above Kawanakajima

Korinji Temple (光林寺, also written Kōrin-ji) is a Jōdo-shū Buddhist temple on raised ground in Shinonoi Komatsubara, Nagano City, Nagano Prefecture, whose main hall of 1800 and three other buildings in its precinct are Registered Tangible Cultural Properties. Its full formal name, 亀見山無量院光林寺, prefixes a mountain name and a cloister name to the temple name, as Japanese Buddhist temples traditionally do.

The precinct sits a step above the houses of Shinonoi. The Agency for Cultural Affairs describes the main hall as standing on high ground that looks down over Kawanakajima, the plain where the Takeda and Uesugi armies met repeatedly in the 16th century. Visitors arrive from the east, climbing a flight of stone steps; the gate waits at the top and the main hall stands beyond it.

Nagano City's cultural property database relates a local tradition that Takeda Shingen used Korinji as a camp during the Kawanakajima campaigns. Treat this as legend: no public record confirms the camp, and the published primary sources do not give a founding date for Korinji Temple either.

The four registered buildings of Korinji Temple

Korinji's buildings were registered in two rounds. On December 5, 2019, the sutra repository, the bell tower and the main gate became Registered Tangible Cultural Properties on the same day, under consecutive numbers 20-0550 to 20-0552. The main hall followed on August 6, 2025, as number 20-0669.

• Main hall: 1800, renovated in 1978. A hip-roofed hall with a porch, building area 312 square meters
• Main gate: 1826. A one-bay yakuimon gate with a frontage of 3.4 meters and short flanking walls
• Bell tower: 1830. Hip-and-gable roof of tiles, area 8.9 square meters
• Sutra repository: 1865, renovated in 1965. A plastered storehouse holding an octagonal revolving bookcase, building area 52 square meters

All four date from the late Edo period. In order of construction they run main hall, gate, bell tower, repository, so the temple's present core took shape over roughly 65 years. Every one of them carries carved or painted ornament, and a slow circuit of Korinji Temple shows how much attention rural temples in Shinano lavished on decoration at that time.

According to the city database, a founder's hall and a Jizo hall also stand in the precinct. They are not part of the registration.

Walking the precinct of Korinji Temple

The gate and the main hall of Korinji both face east. The main gate stands midway along the eastern edge of the precinct, right where the steps arrive, and the porch of the main hall lines up directly behind it. Think of the gate-to-hall line as the spine of the precinct and the rest falls into place.

From the front of the main hall, look back toward the northeast corner. The bell tower stands there on a stone platform built on top of a retaining wall, raised high enough that its roof is visible from the approach below. The Agency calls it a symbol of the hilltop precinct, and from this angle it is easy to see why.

Walk south from the hall instead and you reach the white plastered sutra repository near the southern side of the grounds. Unlike the gate and the hall it faces north, so coming from the hall you meet its doorway and the bell-shaped window frames head on. Gate, hall, bell tower, repository: that sequence takes you around Korinji Temple and back to the steps.

In spring a weeping higan cherry flowers in the precinct, and the city database singles it out as a fine sight. Bloom dates shift from year to year, so check before you travel.

Getting to Korinji Temple and visiting

The nearest station to Korinji Temple is Imai on the Shinano Railway. From there the temple lies about 2.5 km west by road, a walk of a little over 30 minutes that ends with a climb up the terrace edge and the stone steps. Trains on the Shinano Railway run through to Imai from Nagano Station; a taxi from the station is the easier option for anyone short on time.

Korinji is a working parish temple rather than a tourist site, and it publishes no visiting hours or admission fee. The four registered buildings are seen from the outside, from within the precinct. If you hope to see inside the main hall or the revolving bookcase in the repository, contact the temple in advance and fit around its services. There is no published photography policy either, so ask before photographing interiors or ceremonies.

Parking is not officially described. If you come by car, make sure you are not blocking local residents before leaving the vehicle near the temple.
