Jōshō-ji Sanmon: A Cypress-Bark Gate on the Old Kiso Road
A short flight of stone steps in the village of Ōkuwa climbs to a small gate roofed in layered cypress bark. This is the Sanmon, the main gate of Jōshō-ji, a Rinzai Zen temple in the Suhara district of the Kiso Valley in southern Nagano. It was built in 1661, carries a single doorway under one gabled roof, and belongs to a class of gate that Japanese carpenters call shikyakumon, literally a "four-legged gate."
The temple stands just off the old Nakasendō, the inland highway that once linked Edo (present-day Tokyo) with Kyoto. Suhara was the thirty-ninth of the road's sixty-nine post stations, and travelers heading south through the mountains passed within a few minutes' walk of these steps.
A Temple Older Than Its Buildings
Jōshō-ji was founded in the late 1380s by Kiso Chikatoyo, the eleventh head of the Kiso family, who established it beside the Kiso River in memory of his ancestors. The river proved an unstable neighbor. In 1448 the first temple, said to have held a full set of seven halls, was washed away in a flood.
It was rebuilt in 1454 by Kiso Iekata, with a monk named Kōrin Egan, who came from Jōchi-ji in Kamakura, installed as the fourth abbot and restorer. Further flooding forced the temple to relocate more than once. The buildings that survive today were raised on the present hillside site around 1598, under Ishikawa Mitsuyoshi, the magistrate then administering the Kiso district.
Three of those structures are designated Important Cultural Properties: the main hall, the kuri (the kitchen and living quarters), and the Sanmon. The main hall and kuri date from the early Edo period. The gate, dated by an inscribed ridge tag, was finished in 1661, a few decades later than its neighbors.
Why the Gate Was Designated
The Sanmon was registered as a national Important Cultural Property on 29 March 1952, together with the main hall and kuri. Three years earlier, in 1949, the same three buildings had been listed as Important Art Objects for their Momoyama-influenced character.
What gives the gate its standing is the pairing of a securely dated early Edo construction with a well-preserved shikyakumon form. The type takes its name from the four slanting support posts set in front of and behind the two main pillars. A single bay frames one doorway, and the roof follows kirizuma-zukuri, a plain gabled form whose two slopes meet along a straight ridge. The covering is hiwadabuki, finely layered cypress bark, a roofing method used for buildings of some rank and costly to keep up.
The inscribed ridge tag that records the gate's construction is preserved with it and is itself counted in the designation.
What to Look For
The gate rewards a slow approach. Seen from the foot of the steps, the cypress-bark roof reads as a low, level line against the wooded slope behind it. Up close the bark is laid in fine overlapping courses rather than tiled, giving the surface a soft, slightly furred texture quite unlike a hard ceramic roof.
Look at the joinery where the four support posts meet the main pillars, and at the bracketing tucked under the eaves. The carpentry here is restrained. A description on the temple grounds sums up the whole complex as plain yet powerfully built, a contrast to the gilded flamboyance often associated with Momoyama taste.
In late autumn the maples flanking the stone stairway turn red and gold, and the gate is at its most striking framed by that color. The approach from below, with the roofline rising out of the foliage, is the view most visitors come away with.
Beyond the gate the precinct holds more. The main hall has a "nightingale" floor whose boards chirp underfoot, and it houses the Jōshō Daruma, a large seated image of Bodhidharma carved in 1964 from roughly six cubic meters of Kiso cypress. To one side lies the Tsuru-Kame Hōrai garden, a dry-landscape composition by the contemporary garden designer Oguchi Motomi.
The Oldest Record of Cut Soba
Jōshō-ji holds a large body of medieval documents, and one of them has turned the temple into a quiet place of pilgrimage for noodle enthusiasts. A construction account kept in 1574, while the Buddha hall was being repaired, itemizes the materials, the wages paid to carpenters and smiths, and the food and drink provided. One short line notes that a man named Kin'ei served sohakiri, soba cut into strands.
This is generally cited as the oldest written reference in Japan to soba eaten as cut noodles, rather than as the porridge or dumplings in which the grain had long been consumed. The record predates the present gate by nearly ninety years, a useful reminder that the temple's story runs well behind the buildings now standing on the hill.
Around the Temple
Suhara still keeps much of the shape of a Nakasendō post town, and the walk from the railway station to the temple leads through it. Jōshō-ji is the oldest of the three so-called great temples of Kiso; the other two, Kōzen-ji and Chōfuku-ji, lie to the north in Kiso Town and round out a day spent following the valley's Zen heritage. Hakusan Shrine, about five minutes away by car, preserves a shrine building from the Kamakura period that is also a national Important Cultural Property.
Jōshō-ji is reached on foot in about ten minutes from Suhara Station on the JR Chūō Main Line, or in roughly forty-five to fifty minutes by car from the Nakatsugawa interchange. The grounds are open through the day, with shorter hours in winter.

Q&A
- Can I go inside the buildings?
- The main hall entered a seismic-strengthening project in late 2024, and interior viewing has been limited while the work continues. The gate stands outdoors and can be seen at any time, and the garden has generally remained open. It is best to check current conditions with the temple before a visit.
- How do I get to the temple?
- It is about a ten-minute walk from Suhara Station on the JR Chūō Main Line. By car it is roughly forty-five to fifty minutes from the Nakatsugawa interchange on the Chūō Expressway.
- Is there an admission fee?
- Walking the grounds and viewing the gate is free. Interior viewing, when available, has carried a small charge of about 300 yen.
- When is the best time to visit?
- Late autumn is the most popular season, when the maples along the stone steps below the gate turn color. Early summer green and a quiet winter snowfall each have their own appeal.
- What does "four-legged gate" mean?
- A shikyakumon has two main pillars carrying the roof, with four additional slanting posts set in front and behind to brace them. The name counts those four bracing posts. It is a classic, dignified gate form used at temples and shrines of standing.
