A Fire Ritual Hall Under a Double Roof

Zentsuji Tanjoin Temple Goma Hall is a single-storey wooden Buddhist hall in Zentsujicho, Zentsuji City, Kagawa Prefecture, built in 1940 and listed as a Registered Tangible Cultural Property in 2010.

It faces south, northeast of the Shoryoden Hall. The plan is three bays by three, the interior divides into an inner and an outer sanctuary, and a veranda runs around the outside. The Hōgyō-zukuri pyramidal roof is sheathed in copper and built up in two tiers rather than one, with a one-bay Kōhai canopy projecting at the front. The building covers 79 square metres.

Goma is the Shingon fire ritual, in which offerings are burned before an altar, and the hall named for it occupies the northern quarter of the precinct. The Jizo Hall lies to the west of Zentsuji Tanjoin Temple Goma Hall and the Shoryoden Hall to the southwest, the three linked by a covered corridor.

Old Forms in a Modern Building

Zentsuji Tanjoin Temple Goma Hall was registered under the criterion of contributing to the historic landscape of the country, as number 37-0343.

The official description dwells on the detailing. The posts are round, the bracket sets are of the Mitsudo-gumi type, and short struts stand between them. The eaves carry two tiers of widely spaced rafters. Nose pieces, Kaerumata frog-leg struts and bracket arms are all cut in forms borrowed from earlier centuries. A building of 1940 was finished in a deliberately archaic idiom, and that is the substance of the case for listing it.

Japan's registration system covers buildings more than 50 years old, so a good deal of modern work falls within it. This hall shows how far traditional carpentry techniques were still being practised in the years before the Second World War.

What to Look For

Seen head on, the roof clearly rises in two stages, the lower covering the body of the hall and a smaller upper tier sitting above it. Against a single pyramidal roof the arrangement gains shadow and apparent height.

Then step in and look up under the eaves. Bracket sets and struts alternate at regular intervals above the posts, with rafters running in two layers behind them. The carving on the nose pieces and frog-leg struts is deep, set off against the settled green of the copper. The densest concentration of timber on Zentsuji Tanjoin Temple Goma Hall is directly under the front canopy, which is where it pays to stop.

Visiting Zentsuji Tanjoin Temple Goma Hall

The hall stands north of the Mieido Hall at the end of the covered corridor. Its south face is clear of other buildings, making it one of the few structures in the precinct that can be seen whole from directly in front.

The temple publishes opening hours for the main hall and the Mieido Hall; no interior visit is advertised here. When a fire ritual is held, people gather in front of the building and it is better viewed from a distance. Nothing is posted about photography, so ask at the desk inside the Mieido Hall if you intend to shoot into the interior.
