The Gate That Meets You First
Long before the main hall of Unpoji comes into view, the climb up the stone approach delivers you to a gate. Set among tall cedar and cypress on the road toward the Daibosatsu Pass in Koshu, Yamanashi Prefecture, the Niomon is the first structure a visitor passes. It is a three-bay, single-entrance hakkyakumon, an "eight-legged gate" whose name comes from the eight supporting posts that flank its central passage. A hip-and-gable roof, now finished in copper plate, sits over the whole.
The gate takes its name from the two Nio, the muscular guardian kings stationed left and right of the opening. One holds his mouth open, one holds it closed, together sounding the first and last syllables of the Sanskrit alphabet. Walking between them is the point: you leave the mountain road and enter temple ground.
A Muromachi Gate on an Ancient Site
Unpoji traces its origin to a legend of 745, when the monk Gyoki is said to have carved an eleven-headed Kannon from a tree grown out of a split rock, giving the temple its mountain name Sakeishizan. By the late medieval period the house had become a Rinzai Zen temple and a prayer hall of the Takeda clan, whose seat lay to the southwest.
The Niomon belongs to the late Muromachi period, the same building campaign that produced the main hall after a fire in the mid-16th century. The national cultural-properties database records its date as the span 1467 to 1572. Together with the main hall it was designated an Important Cultural Property on 18 February 1949. The two structures share a vocabulary of restraint that marks the compound as the work of a single era.
What to Look For
Pause under the gate and look up into the framing. In an eight-legged gate the load of the roof is carried down through paired posts front and back of the central bay, leaving the passage open and the structure legible overhead. The copper roof has weathered to a soft green, a later covering that protects the timber of the older frame.
Notice, too, where the gate sits in the sequence of the climb. The approach rises through 198 stone steps; the Niomon marks the point where the forest thins and the temple begins. Above it wait the main hall, the shoin set behind a garden, and the priests' quarters to the right. If you have arranged a viewing of the treasure hall, this is also the threshold you cross on the way to the Takeda war banners kept within, among them the tall Sun Tzu banner known for the phrase read as "wind, forest, fire, mountain."
