Kokokuzan Tokushoji Konpirado

Ten Square Metres, and the Oldest Thing Standing

Kokokuzan Tokushoji Konpirado (興國山徳昌寺金毘羅堂, also written Kōkokuzan Tokushō-ji Konpira-dō) is a small hall dedicated to the deity Konpira on the grounds of a Soto Zen temple in Tajima, Minamiaizu Town, Fukushima Prefecture, built in 1776 and entered on the national register of tangible cultural properties in 2001.

It measures ten square metres. That is smaller than a parking space and a rounding error beside the main hall's 327, yet this is the oldest surviving building at Tokushoji by nearly half a century. The main hall dates from 1844, the priests' quarters from 1820. The little hall northeast of them was already sixty-eight years old when the main hall went up around it.

Konpira is worshipped for safe passage. The cult centres on Kotohira-gu in Sanuki, present-day Kagawa Prefecture, and the deity was invoked above all by sailors and by anyone whose living depended on getting from one place to another intact. During the eighteenth century, confraternities called Konpira-ko carried the worship far inland, spread along trade routes by merchants and packhorse drivers rather than by any central authority. Tajima sat on the Aizu Nishi Kaido, the road linking the Aizu basin with Nikko and the Kanto plain, and functioned as a post town. No surviving document at the temple explains why a Konpira hall was built here in particular, but a mountain post town whose economy ran on traffic over dangerous passes is not an unlikely place to find one.

What the Plaque Inside Records

The hall is precisely dated, and the evidence sits inside it. A senguu meifuda, a wooden plaque recording the enshrinement of the deity in the building, gives the fifth year of the An'ei era, 1776. The same plaque names the carpenter: Sato Chuji of Tajima Higashimachi.

That name is the interesting part. Tokushoji's main hall of 1844 was built by a carpenter brought in from Kanbara District in Echigo, on the far side of the mountains. The Konpira hall, seven decades earlier, was the work of a man from the east ward of Tajima itself, a few minutes' walk down the hill. Two commissions at the same temple, two entirely different procurement decisions. The small hall came from the neighbourhood; the big hall came from over the pass.

Registration followed on 24 April 2001, with public notice on 15 May, in the twenty-eighth round of registrations. The register number is 07-0051, and the criterion applied, as with the temple's other two registered buildings, was that the structure is a model of design.

Small Building, Orthodox Carpentry

The hall is a three-bay type, with the frontage and the depth each measuring a little over ten shaku, roughly three metres. Three bays across three metres means each bay is about a metre wide, so the divisions read as slender rather than generous. Roofing is copper sheet, and the structure is timber on a single level.

Two details reward a close look. The first is the eaves, which project further than the building's size would lead you to expect. They are carried on degeta construction, a method in which a purlin is pushed outward on projecting members to extend the overhang. It is a technique associated with shrine and hall carpentry, and applying it to a structure this small was a choice about dignity rather than about shelter.

The second is the bracketing. The perimeter posts are square in section, which is the plain option, and the bracket complexes are mitsudo, three-block sets, which is close to the simplest arrangement in the repertoire. Nothing here is showing off. What specialists note is that the simplicity is orthodox: the proportions and the assembly follow correct practice for a hall of this class, executed by someone who knew the rules rather than someone improvising. That combination, modest means and disciplined method, is what the registration recognises.

Local documentation adds detail the national record leaves out. Signboards prepared by the town board of education describe an irimoya hip-and-gable roof, a one-bay porch roof across the front, and exterior walls of boarding set between exposed posts. These readings are consistent with the building but rest on municipal survey rather than on the Agency for Cultural Affairs record, which lists only material, roofing and floor area.

Visiting is simple. The hall stands in the open on the grounds northeast of the main hall, the grounds are freely accessible, and there is no charge. A structure of this size has no interior to enter, so what you get is the exterior, which is the point. Photographing it from outside is generally accepted. The temple can be reached in about five minutes by car from Aizu-Tajima Station on the Aizu Railway, and there is parking on site; the telephone number is 0241-62-0255.

Seeing all three registered buildings takes perhaps twenty minutes, and the walk between them covers seven decades of local carpentry. Tokushoji is also the fifteenth stop on the Gokurairi thirty-three Kannon pilgrimage through the Okuaizu mountains, so the grounds see a steady trickle of pilgrims collecting stamps. In late July the Aizu-Tajima Gion Festival fills the streets below from the twenty-second to the twenty-fourth.
