Iimoriji Temple Main Hall

Hanjōji Hondō: A Mountain Hall in the Wakasa Forest, Untouched Since 1489

Halfway up Mount Iimori in Fukui's Obama City, beyond a narrow road that climbs through cedar groves and curls of mountain stream, sits a wide, low temple hall whose timbers have stood since five years before Columbus reached the Americas. This is the main hall of Hanjōji, a Shingon temple founded—if the legends are to be believed—more than thirteen hundred years ago. The current building dates from 1489, and despite a roofing change and a careful 1998 dismantling, its essential form has scarcely changed since the late Muromachi period.

Hanjōji sits far enough off the modern tourist trail that you may share it only with the temple's mascot dog, Gin-chan, who greets visitors with an enthusiastic bark. Yet the hall before you is no minor relic—it is a nationally designated Important Cultural Property and one of the most significant medieval Buddhist halls in the Wakasa region.

A Curious Three-Way Reading

One quirk to know before you go: the three Chinese characters 飯盛 are read three different ways in this single corner of Obama. The neighborhood is "Hansei," the mountain is "Iimoriyama," and the temple is "Hanjōji." Locals enjoy pointing this out to visitors, and it is a useful reminder that Japanese place names carry layers of history rather than fixed pronunciations. The mountain name comes from its rounded silhouette, said to resemble a heaped bowl of rice (iimori), while the temple uses the more formal Sino-Japanese reading associated with Buddhist institutions.

The Temple's Long Story

According to temple tradition recorded in old gazetteers of Wakasa, Hanjōji was first founded during the Yōrō era (717–724) by imperial command of Empress Genshō. That early hall, however, stood elsewhere in the area. The temple as it is known today was reestablished on its present mountainside site during the Bunna era (1352–1356) under the patronage of Emperor Go-Kōgon, who designated it a chokuganjo, or imperial prayer temple. The reestablishment is credited to a priest named Kakunō Hōin.

At its medieval peak the complex held seven principal buildings (shichidō garan) and twelve sub-temples—an extensive precinct for a remote mountain site. Then, in 1484, fire destroyed nearly everything: halls, lodgings, and treasures. Five years later, in 1489 (the first year of the Entoku era), the present main hall was completed. This date was confirmed only in 1998, when a full dismantling repair allowed scholars to study inscribed timbers and ridge plaques (munafuda) that had been hidden inside the structure for centuries.

Why This Hall Was Designated

The hall received its national Important Cultural Property designation on January 7, 1983. Three associated items—the inner shrine (zushi) and three ridge plaques—were registered alongside the building itself.

A Rare Survivor of the Wakasa Esoteric Tradition

Wakasa Province (the western half of modern Fukui) preserves an unusually high number of medieval esoteric Buddhist halls, including the National Treasures at nearby Myōtsūji. Even within this rich context, Hanjōji's main hall is valued as a particularly good example of the late Muromachi period preserving notably archaic features. While many halls of the same era had begun to mix architectural styles or refine bracket work into more decorative forms, Hanjōji's builders retained an older, more austere approach.

Pure Wayō Style with Thick, Confident Timbers

Architectural historians describe the hall as a model of authentic wayō—the so-called "Japanese style" of Buddhist architecture that crystallized in the Heian and early medieval periods. The proportions are deliberately heavy: the kiwari, or relative thickness of structural members, is generous, giving the hall a settled, grounded presence. The bracketing is the relatively simple deshi-mitsudo type, the head-tie beams are finished with kibana nose-shaped projections, and the spaces between brackets carry plain bachi-zuka struts. Nothing is showy; everything is structurally honest.

A Five-by-Five Bay Square Plan

The hall measures roughly thirteen meters on each side, with a five-by-five bay square plan. Inside, a three-by-three bay inner sanctuary is wrapped on all four sides by a single bay of perimeter aisle, with a wide rainbow beam (kōryō) opening up the front. A one-bay forecourt prayer chamber (kōhai) projects from the entrance, and a continuous wooden veranda runs around all four sides. The hall is set on a foundation built up of rough natural stones—a quietly characterful base that anchors the building to its mountain slope.

The Story of the Roof

The roof has had an interesting journey. Originally thatched in miscanthus reed (kayabuki), it was converted to ceramic tile (sangawara-buki) in the modern era for ease of maintenance. Then, during the comprehensive 1998 conservation project, the thatched roof was reinstated, restoring the building's silhouette to something much closer to its medieval appearance. The ridge of the hall is finished as a hipped roof (yosemune-zukuri), with the gable end—rather than the long side—facing forward, an unusual orientation called tsumairi.

What to See Inside and Around

The Healing Buddha and the Thousand-Armed Kannon

The principal image enshrined within is a seated statue of Yakushi Nyorai, the Buddha of Healing, traditionally invoked for the relief of illness and bodily suffering. Flanking the main altar is a standing image of Senju Kannon, the Thousand-Armed Avalokiteshvara, bodhisattva of boundless compassion. This pairing fits Hanjōji's role as the twenty-fourth station on the Wakasa Kannon pilgrimage circuit, a centuries-old route through the temples of the region.

A Hall You Can Sit In

Unusually for a building of this importance, Hanjōji actively invites visitors to use the hall, not merely look at it. The temple offers seated meditation (zazen) sessions inside the main hall itself, an opportunity to sit on six-hundred-year-old floorboards beneath six-hundred-year-old timbers. Sutra copying (shakyō) is available in the guest hall, and the temple also runs informal terakoya programs for children and occasional running events on the temple grounds.

The Fudō Waterfall

A short walk beyond the main hall, deeper into the forest, brings you to Fudō Falls (Fudō-taki), where Namikiri Fudō—a "wave-cutting" form of the wrathful protector deity—is enshrined above the water. The walk is brief but feels removed from the world; in spring, white plum blossoms scent the path, and in summer the cascade is the centerpiece of the Taki-matsuri waterfall festival held every July 28.

Yearly Rhythm

The temple keeps a full calendar of esoteric rites. Highlights include the Setsubun-e on February 3 with a fire ceremony for the year's astrological protection, a Saitō Goma open-air fire ritual in March, the Taki-matsuri in late July, the Segaki ancestral memorial service on August 15, and the New Year's Eve bell ringing. Monthly Fudō goma fire rituals continue year-round.

Visiting Hanjōji

Hours and Admission

The temple is open for viewing from 9:00 to 17:00. Admission is 400 yen. Goshuin (calligraphic temple stamps) for both Yakushi Nyorai and Senju Kannon are available year-round. Because this is a working temple in a quiet mountain setting, it is courteous to phone ahead at 0770-52-6692 if you wish to ask about meditation, sutra copying, or interior viewing of the main hall.

How to Get There

Hanjōji is best reached by car. From JR Obama Station, the drive takes about 25 minutes. From the closer JR Kado Station, it is about 4 kilometers south into the hills. Note that the final approach climbs a narrow mountain road of roughly one kilometer, with sections where two cars cannot pass and few places to turn around—drive slowly and check ahead before setting out.

When to Come

Hanjōji is rewarding in every season. Spring brings plum and cherry to the lower precincts; summer drapes the hall in deep mountain green; autumn leaves frame the dark beams of the veranda; and winter, with snow on the thatched ridge, returns the building to something approaching its medieval picture. The mountain road can be snowy and slippery in deep winter, so check conditions before driving up.

While You Are in Obama

Hanjōji is one of many medieval temples preserved in the Obama area, an old port town historically known as the "kitchen of the imperial court" for the seafood and salt sent inland to Kyoto. Visitors interested in Wakasa's religious architecture often combine a trip with the National Treasure halls of Myōtsūji, the imperial-patronage temple of Hagaji with its eleven-faced Kannon, and Jingūji, the source temple for Nara Tōdaiji's annual Omizu-okuri water-sending ceremony. The Obama 8-temple circuit (Obama Hakkaji-meguri) groups these and others into a recognized walking and driving route. The local seafood—particularly the sweet-fleshed mackerel served along the historic Saba Kaidō, or "mackerel road"—is reason enough to stay overnight.
