A Muromachi Zen Hall Above the Daibosatsu Road
A stairway of 198 stone steps, shaded by cedar and cypress, climbs from the old Ome road toward the Daibosatsu Pass. At the top stands the main hall of Unpoji, a Rinzai Zen temple in the Enzan district of Koshu, Yamanashi Prefecture. It measures five bays across and five bays deep, carries a single-story irimoya (hip-and-gable) roof laid in layered cypress bark, and steps forward at its center into a one-bay worship porch capped by a karahafu, the undulating gable that carpenters kept for buildings of standing.
The mountaineer and essayist Fukada Kyuya, surveying the country's hundred famous mountains, stopped here and described the hall simply as a fine building of cypress bark and hip-and-gable lines. Anyone who reaches the summit of the approach and turns to face it tends to agree.
From a Split Rock to the Takeda Prayer Hall
Temple tradition dates the origin to 745, when the monk Gyoki is said to have carved the temple's eleven-headed Kannon from a hagi tree that grew overnight from a cleft boulder. That legend gives the temple its mountain name, Sakeishizan, the "split-rock mountain," and its principal image, known as the Sakeishi Kannon. The house was originally Shingon or Tendai and later passed into the Rinzai school as a branch of nearby Erinji.
Because the compound sat at the northeastern approach to the Takeda clan's territory, the direction traditionally guarded against misfortune, it became a prayer temple of the warlords of Kai. A fire during the Tenbun era (1532 to 1554) damaged the buildings, and reconstruction followed with the backing of Takeda Nobutora and his son Shingen. The present main hall belongs to the late Muromachi period; the national database records its date only as a span, 1467 to 1572. On 18 February 1949 it was designated an Important Cultural Property.
What to Look For
Stand at the foot of the worship porch and look up. The karahafu over the central bay reads as a single slow curve, and the cypress-bark roof above it is built from thin strips stacked by hand rather than fired tiles, a technique that gives the eaves a soft, layered edge. The hall keeps the restraint of Zen carpentry: little painted ornament, weight carried in the timber itself.
Behind the worship of the Kannon lies the reason many visitors climb the steps. Unpoji keeps a treasure hall where the war banners left by Takeda retainers are shown. Among them is the famous Sonshi banner, roughly 3.8 meters tall, inscribed with the four phrases from Sun Tzu popularly read as "swift as wind, silent as forest, fierce as fire, immovable as mountain." Beside it hang what the temple describes as the oldest surviving Hinomaru sun-disc banner in Japan and a banner bearing the name of the Suwa deity. By tradition these were deposited here in 1582, after Takeda Katsuyori and his family died at nearby Tenmokuzan. The treasure hall is opened on request, so call ahead before visiting.

Q&A
- How old is the main hall?
- It dates to the late Muromachi period. The national cultural-properties database gives the range 1467 to 1572, consistent with the reconstruction that followed the mid-16th-century fire.
- What is a karahafu?
- It is a curved, cusped gable used over an entrance or porch. Here it crowns the one-bay worship porch that projects from the front of the hall.
- Can I see the Takeda banners?
- Yes, in the temple's treasure hall, but it is shown by reservation. Phone the temple in advance to arrange a viewing.
- How do I reach Unpoji?
- From Enzan Station on the JR Chuo Line, take the bus bound for the Daibosatsu trailhead to the last stop, then walk about five minutes. Free parking is available at the temple.
- Is the roof made of tiles?
- No. It is a cypress-bark roof, built from thin layers of bark rather than ceramic tiles, which suits the quiet character of a mountain Zen temple.
