What Is the Kannonji Temple Main Hall?
The Kannonji Temple Main Hall (観音寺本堂, Kannon-ji Hondō) is a late Muromachi period (1467 to 1572) Buddhist hall at Shiofune Kannonji Temple in Shiofune, Ome City, Tokyo, designated an Important Cultural Property of Japan on November 29, 1946, together with the Zushi shrine cabinet inside it.
This is the hall of the temple's principal image, a thousand-armed Kannon, and the Tokyo Metropolitan Government's commentary also calls it the Kannon Hall. It measures 5 by 5 bays, roughly 12 meters on each side, and is covered by a single large Yosemune-zukuri hipped roof of Kayabuki thatch. Of the temple's three historic buildings, the Kannonji Temple Main Hall stands highest and farthest in, on a leveled terrace halfway up the hillside at the top of a flight of stone steps.
Why the Kannonji Temple Main Hall Matters
What makes the Kannonji Temple Main Hall significant is how faithfully it preserves the layout of a medieval esoteric Buddhist hall. Inside, a lattice screen on a low sill, called the kekkai, divides the floor in two: the Gejin, or outer sanctuary where worshippers sit, and the Naijin, the inner sanctuary that houses the images. This front-and-back division is the standard plan of halls of the esoteric schools, and the inner sanctuary has a screen wall behind the altar and a raised Shumidan platform.
Its date rests on details. The bracket sets on top of the inner pillars are basically in the native Wayō style with elements of the Zenshūyō Zen style added, and together with the carved patterns on the projecting beam ends, or Kibana, they point to the late Muromachi period. The Agency for Cultural Affairs gives the same dating.
The shrine cabinet designated with the hall is described in the Tokyo commentary as exceptionally fine work. It sits on the altar platform and holds the principal image. That hall and cabinet survive together from the same period adds weight to the designation.
What to Look For at the Kannonji Temple Main Hall
Climbing to the front of the Kannonji Temple Main Hall, the first impression is austerity. The walls are plain boards and board doors on all four sides, with almost no paint or carving, and the heavy thatched eaves hang low enough that you cannot see inside. The Tokyo commentary describes the exterior as very simple and the interior as a closed space.
The national database lists the roof as thatch, but the temple explains that cedar bark is worked in among the grass, a mixed technique known in the Okutama area as torabuki, or "tiger thatching." If you can get close to the eaves, it is worth comparing the two materials in the layers. Seen from an angle, the broad hipped roof also gives the best sense of the hall's square bulk.
The floor inside is boarded and the ceiling is a flat Kagami-tenjō mirror ceiling. According to the temple, the doors of the shrine cabinet are painted on the inside with the bodhisattvas Fugen and Monju, figures of Bishamonten and Fudo Myoo stand on either side, and beyond them the 28 attendant deities of the thousand-armed Kannon crowd the altar. The hidden principal image is the work of the sculptor Kaisei, and both it and the 28 attendants are separately designated Important Cultural Properties. An inscription on its pedestal records a repair in 1512 sponsored by Mita Ujimune and his son Masasada, showing how closely the hall was tied to the local Mita lords.
The two giant cedars that frame the steps up to the hall are a Tokyo Natural Monument. From the foot of the steps, the thatched roof of the Kannonji Temple Main Hall shows between their trunks.
Visiting the Kannonji Temple Main Hall
The exterior of the Kannonji Temple Main Hall can be viewed freely from the terrace in front of it. For the roof, step back and look from a front corner. Expect stone steps and a slope on the way up.
The hall is still used for prayer services, including New Year fire rituals and readings on the 16th of each month, the Kannon's monthly feast day. The temple says the doors of the cabinet holding the hidden image open four times a year: January 1 to 3, January 16, May 1 to 3, and the second Sunday of August. In May, the image can be seen on the 1st from the 1:00 p.m. fire ritual until 4:00 p.m., and from 9:00 a.m. to 4:00 p.m. on the 2nd and 3rd.
The temple does not say whether visitors may enter the hall on other days or take photographs inside. Prayer requests and enquiries go through the temple office, so check before you visit. Directions and general admission are covered on the Shiofune Kannonji Temple page.
