A Zen-Style Hall at a Pure Land Temple in Okazaki
On the wooded edge of Iwazu, in the northern reaches of Okazaki, a single old hall sits on a low stone platform above a quiet precinct. This is the Kannon hall of Shinkōmyōji, and the first thing worth saying about it is something of a puzzle. Shinkōmyōji is a Pure Land temple, yet its oldest building is built in the Zen manner, the architectural idiom that arrived from China alongside Zen Buddhism itself.
The hall measures three bays on each side, about 7.2 metres across, under a hip-and-gable roof of wooden shingles. A ridge tag preserved in the building records its construction in 1478, the tenth year of the Bunmei era, and four such tags are listed among the designated property's attached items. Originally it served as the temple's lecture hall, the hattō; today it shelters an image of Kannon.
Shinkōmyōji carries the mountain name Mirokusan and belongs to the Chinzei line of Pure Land Buddhism. It was founded in 1451 by Matsudaira Nobumitsu, the third-generation head of the Matsudaira house and lord of Iwazu Castle, to honour his forebears. The Matsudaira were the ancestors of Tokugawa Ieyasu, which gives this modest hillside temple a thread running straight to the founders of the Edo shogunate.
Why the Hall Was Designated
The Kannon hall entered the national register on 18 February 1904. Its importance rests on being a fully realised Zen-style Buddha hall at a Pure Land temple, and one of the oldest such halls the sect retains anywhere in the country. For historians, that combination is a clue to how Pure Land temples took shape in their early centuries and what models they borrowed.
The detailing repays attention. The pillars are round throughout, and the bracketing is the close-packed, two-stepped type with tail rafters that marks the Zen idiom. The doors are panelled, the windows cut in the cusped, flame-topped shape called katōmado. Inside, the floor is bare earth; a mirror ceiling spans the central square while fan-arranged rafters radiate around the outer ring, producing the upward-reaching sense of space that Zen halls cultivate. The roof is large and its eaves curve strongly, set against woodwork kept deliberately fine.
Local tradition holds that the temple's grander buildings were lost to fire set by Ise Shinkurō, the warlord later known as Hōjō Sōun, with only this hall surviving. The details of that account are debated, so it is best taken as the kind of story a place tells about itself rather than settled fact. The year after the hall was raised, in 1479, Emperor Go-Tsuchimikado named the temple a site of imperial prayer.
What to Look For on a Visit
Stand back from the hall and watch the roofline. The strong sweep of the eaves and the bulk of the shingled roof give the building its character, and the corners lift with the tension typical of Zen construction. Step closer and the bracketing, the panelled doors and the cusped windows reward a slower look.
Behind the hall lie the graves of three generations of the Matsudaira house, set within a low earthen wall, a reminder of the family that would one day rule Japan. The temple stands near the ruins of Iwazu Castle and the Iwazu Tenmangū shrine, so the three sites combine well, especially when the shrine's plum trees flower in late winter. Admission to the precinct is free, and the setting stays quiet through most of the year.
