One of the small shrines behind the main hall
Behind the Shoden hall stand three small shrines, and the northerly of them is the Sanpo Kojinsha. It is a single-bay shrine built in nagare-zukuri form, the type whose front roof slope sweeps down further than the back in a single flowing line. Left in unpainted timber (shiraki) and roofed in copper, it covers a mere 3.9 square meters. It was raised in 1787, in the Tenmei era, and repaired in 2011.
The deity is Sanbo Kojin, a guardian associated with fire and the hearth and, by extension, with the three treasures of Buddhism. Small shrines to such deities were often tucked behind a main hall, close to the sacred core but out of the main sightline.
Tiny, and unmistakably skilled
The shrine was registered on 2 May 2017 among the eight structures around the Shoden hall, on the criterion of contributing to the historic landscape. Its 2011 repair fell in the same period as the major restoration of the National Treasure hall, so the whole rear of the precinct was set in order together.
For its size the workmanship is remarkable. The eaves carry beams of unusual profile, including curved connecting members (ebi-koryo), and frog-leg struts (kaerumata), curved supports (shirin), and carved nose-pieces on the porch posts crowd the small frame. The front porch sits on a low platform (hama-yuka) with a railing carried on shaped brackets around all four sides.
How to see it
Look for it low and to the north behind the great hall. Because it is so small and set back, it rewards deliberate searching rather than a passing glance. Once found, the density of carving on a shrine you could almost span with your arms is the surprise.
Compare it with its near-twin to the south while you are there. Reading the two together shows how the space behind the hall was built up.

Q&A
- Who is Sanbo Kojin?
- A guardian deity linked with fire and the hearth, and with the three treasures of Buddhism. Shrines to Kojin are common at temples, often placed near a kitchen or, as here, behind the main hall.
- What does nagare-zukuri mean?
- It is a common shrine form in which the front slope of the roof extends down in a long, flowing curve past the rear slope. A single-bay version, ikkensha, is the smallest and most frequent type.
- Why is it left unpainted?
- The shrine is built in shiraki, plain unpainted timber, a finish valued in Shinto architecture for its restraint. The carving, rather than color, carries the ornament here.
- Where do I find it?
- It stands behind the Shoden hall, toward the north side, as one of three small shrines set along the rear of the great hall.
