Junseiji Temple Main Hall

A Shin Buddhist Hall in a Forestry Town

Junseiji Main Hall (順誓寺本堂, also written Junsei-ji Hondō) is a Jōdo Shinshū Ōtani-ha temple hall in Shinmachi, Tsubetsu Town, Abashiri District, Hokkaido, completed in 1935 and entered on Japan's register of Tangible Cultural Properties (buildings) on 31 July 2007. It is a single-storey timber building with a sheet-metal roof and a floor area of 203 square metres, set toward the rear of the temple precinct and facing southeast.

Tsubetsu is a forest town. Roughly 86 percent of its area is woodland, and forestry and timber processing have carried the local economy for a century. When the hall went up in 1935, Tsubetsu had been a separate village for only sixteen years, having split from neighbouring Bihoro in 1919. The first generation of settlers was still at work. In a place where timber was the one material nobody had to import, the question was never whether to build in wood but how well the wood could be joined, and that is the question this building answers.

The roof is kirizuma-zukuri, a simple gable. Most Shin Buddhist main halls use irimoya-zukuri, a hipped-and-gabled form, so the choice here stands slightly apart. The triangle of the gable end reads cleanly from the front, and the silhouette is plain and strong. A one-bay kōhai porch projects from the façade. The roof is clad in sheet metal, which in eastern Hokkaido is less a stylistic decision than a practical answer to snow load.

Why It Was Registered

Japan's registration system for buildings uses three criteria. Junseiji Main Hall was listed under the third, which covers structures that contribute to the historical landscape of the country. The emphasis falls less on individual brilliance of design than on a building's role in shaping the place around it. Its registration number is 01-0093; the leading 01 identifies Hokkaido.

The plan measures seven bays by seven, close to a square, and it encloses a large volume.

The Frame Inside

What the Agency for Cultural Affairs singles out is the carpentry within. The interior posts are round in section, and in the gejin, the outer worship area where lay visitors sit, the perimeter posts are tied together by kōryō beams of unusual depth. Depth here means the vertical dimension of the beam in cross-section. Heavy beams spanning between posts let the outer hall open up with very few obstructions, and from a seated position that heft becomes the dominant thing overhead.

Carving on the Structure Itself

The building does not stop at sturdiness. At the boundary between naijin (the inner sanctuary housing the image of Amida Buddha) and gejin, a carved transom is fitted, and above it sit a patterned egyō kōryō beam and a daito sanebijiki bracket assembly. Egyō refers to cloud and scroll motifs cut into the flank of a beam. This is decoration applied to load-bearing members rather than to applied panels, an approach in which the parts doing the most work receive the most attention. The official assessment describes the result as robust and ornate at once.

Practical Notes for Visitors

Junseiji is a working temple where services are still held. Registration as a Tangible Cultural Property assumes that the owner will go on using the building; it is not a museum conversion, and there is no visitor infrastructure. Anyone hoping to see the interior should contact the temple in advance. The precinct is private property, so photography should follow whatever the temple asks.

Getting there realistically means driving. The nearest railway station is Bihoro on the JR Sekihoku Main Line, about 14.5 kilometres from the centre of Tsubetsu, roughly twenty minutes by car. Memanbetsu Airport is about thirty minutes away. Shinmachi sits close to the town centre, within walking distance of the town hall.

A word on winter. Tsubetsu receives heavy snowfall and is designated a special heavy-snow district, and being inland and hemmed in by mountains, it sees days around minus 25 degrees Celsius. A sheet-metal roof is designed to shed snow, so lingering under the eaves is not a good idea.

If you are driving this far, the town rewards a longer stay. Tsubetsu Pass looks down on Lake Kussharo, Lake Chimikeppu sits inside old-growth forest, and the disused Kitami-Aioi railway station has been turned into a small railway park.
