What Is the Kannonji Temple Niomon Gate?
The Kannonji Temple Niomon Gate (観音寺仁王門, Kannon-ji Niōmon) is a late Muromachi period (1467 to 1572) gate at the entrance to Shiofune Kannonji Temple in Shiofune, Ome City, Tokyo, designated an Important Cultural Property of Japan on November 29, 1946.
The Kannonji Temple Niomon Gate stands exactly where the flat land gives way to the hills, marking the formal entrance to the temple precinct. It is a Hakkyakumon, an "eight-legged gate," three bays wide with a single passage through the middle, under a Kirizuma-zukuri gabled roof of Kayabuki thatch. The Tokyo Metropolitan Government's commentary gives its size as about 6 meters by 3.6 meters. A guardian king, or Nio, stands in each of the side bays, which gives the gate its name.
Why the Kannonji Temple Niomon Gate Matters
The Kannonji Temple Niomon Gate is a medieval eight-legged gate that still wears its thatched roof. The Agency for Cultural Affairs dates it to the late Muromachi period, and the Tokyo commentary, comparing its details with the Main Hall, puts it a little later, at the very end of the Muromachi period.
The commentary points to three traits. The posts are relatively tall, giving the gate an upright silhouette. Bracket sets, or Kumimono, are used sparingly, keeping the structure plain. And the central post of each gable end is a single continuous through-post. With almost no ornament, the frame of the gate is left in plain view.
When it was built is uncertain. The 19th-century gazetteer Shinpen Musashi Fudokiko mentions a ridge tablet recording the gate's construction in 1184, but that tablet no longer exists. What survives is a tablet from 1533, recording a repair of the guardian statues under the local lords Mita Masasada and Tsunasada.
What to Look For: The Name Board and the Guardian Kings
Seen head-on from the approach, the central passage of the Kannonji Temple Niomon Gate has no doors, and above it hangs a board bearing the temple's mountain name, Daihisan. The thatch is thick, and together with the tall posts it gives the gate a weighty presence. Walk around to the side and you can see the through-post rising up the middle of the gable, the clearest view of how the gate is put together.
The wooden guardian figures in the side bays were designated Tokyo Metropolitan Tangible Cultural Properties in 1960. Carved from joined blocks of cypress, they show the usual open-mouthed and closed-mouthed pair: the open-mouthed figure grips a vajra in its bent left hand, while the closed-mouthed one thrusts its right palm forward at anyone passing through. The temple gives their heights as 273.4 centimeters for the open-mouthed figure and 277.6 centimeters for the closed-mouthed one.
Their authorship carries a legend. The temple says that when the open-mouthed figure was repaired in 1972, a wooden tag of 1749 was found inside stating that the great sculptor Unkei had made the pair in 1184. The Tokyo commentary, however, sees close parallels with the 28 attendant figures in the Main Hall, in the faces, the muscles and the folds of the drapery, and attributes the guardians to the workshop of the sculptor Jokai in the late Kamakura period. The 1533 tablet names Enkei, a sculptor from Kamakura, as the repairer.
Visiting the Kannonji Temple Niomon Gate
Every visitor to Shiofune Kannonji Temple walks through the Kannonji Temple Niomon Gate, which faces straight down the approach path. Its exterior can be viewed at any time. To appreciate the depth of the thatch and the through-post, step around to look at the gable ends as well as the front.
The guardian statues stand in the side bays, to your left and right as you pass through. Keep a respectful distance and do not touch them. The temple does not state its photography policy, so ask the temple office if you are unsure. Directions and general admission are covered on the Shiofune Kannonji Temple page.
