The Oldest Timber Building in Aichi, National Treasure since 1955
Konrenji Midado (金蓮寺弥陀堂) is a Kamakura-period Buddhist hall at 1 Nanadogairi, Aeba, Kira-cho, Nishio City, Aichi Prefecture, designated a National Treasure in 1955, on 22 June. It had become an Important Cultural Property on 15 April 1920. The quantity is one building. It belongs to Konrenji.
Its form is recorded as three bays along the front, three bays deep, single storey, hipped roof, with an aisle one bay deep across the front and a two-bay aisle at the rear of the left side under a sloping gable, roofed in cypress bark. The Agency for Cultural Affairs is brief: an example of Amida hall architecture, in a domestic manner.
Descriptions calling this the oldest wooden building in Japan are mistaken. Nishio City and Aichi Prefecture both record it as the oldest timber structure in the prefecture, older within Aichi than the keep of Inuyama Castle or the Joan tea house, both National Treasures.
The Records Differ on Its Date
Accounts of the building's date differ even within the official record.
The Agency's database gives the period as late Kamakura, 1275 to 1332, while its commentary states that the hall was built in the early Kamakura period. Early and late stand side by side in the same record. Nishio City holds that style and technique place it in the middle Kamakura period.
This article does not choose among them, recording only that the building is of the Kamakura period and that the accounts vary.
A tradition surrounds its founding: that in 1186 Minamoto no Yoritomo ordered Adachi Morinaga, military governor of Mikawa, to raise it as one of the seven halls of Mikawa. No documents survive, however, and the circumstances of its founding are unknown. The traditional year, 1186, does not agree with the date suggested by the style.
What "Domestic Manner" Means Here
The Agency's phrase, in a domestic manner, rests on the detail of the treatment.
The outer aisle across the front is left open, the columns are heavily chamfered, the brackets are simple boat-shaped members, the outer flying rafters are set at wide intervals, and the fittings on the front are hinged shutters. All of these belong to the manner of Heian aristocratic houses and of the imperial residence.
The techniques of a nobleman's dwelling are applied to a temple building. Nishio City likewise notes chamfered square columns, half shutters, board doors and sliding lattice doors, describing the treatment as a quiet residential manner.
The plan is distinctive too. Heian Amida halls are commonly three bays square with four columns at the centre carrying the image, but Konrenji Midado has no such central columns; its two columns behind the image are set back from the line of the outer columns. No columns stand at the centre of the hall.
Some Twenty Amida Halls Survive
Amida halls built up to the Kamakura period survive in something over twenty examples across Japan.
Among these, Konrenji Midado was designated for the refined beauty of a Buddhist hall in a domestic manner. Rarity is joined by that domestic character in the assessment. The Fudodo at Kongobuji in Wakayama, also a National Treasure, is a building of the same kind.
The roof was tiled for a period. Dismantling and repair in 1954 restored the original cypress bark, and designation as a National Treasure followed the next year. The designation came directly after the restoration work.
Between 2015 and 2016 the cypress bark was relaid and seismic strengthening carried out. The strengthening was installed beneath the floor so as not to alter the exterior, and steel members can be seen by looking under the veranda.
Visiting
The exterior can be seen freely from the precinct. Entering the hall requires a booking in advance.
Interior viewing is arranged through the Kira volunteer guides. Guided viewings are held on Sundays in May, and during that period entry may be possible without a booking. Whether they run varies by year, so check beforehand.
Admission is 300 yen, applied to the upkeep of the hall. The Amida triad enshrined within is an Aichi Prefecture cultural property, a designation separate from the building.
The precinct lies among fields, with the hall standing beside the main hall of the temple. The deep eaves and the gentle curve of the roof change in appearance with the viewing position. From Kira-Yoshida Station on the Meitetsu Nishio Line it is about ten minutes by car.
