Yoga Shrine Tower Gate

A Momoyama Gate Beside the Castle Moat

The Rōmon of Yoga Shrine (与賀神社楼門, also written Yōka-jinja and read Yoka-jinja locally) is a two-storied wooden gate in Yoga-machi, Saga City, Saga Prefecture, dated by the Agency for Cultural Affairs to the Momoyama period of 1573 to 1614 and designated an Important Cultural Property on 14 April 1913.

You reach it from the west. A low stone torii sits almost on the pavement of a one-way lane, then a short arched stone bridge crosses the water, and only after that does the gate appear, painted a deep red that has weathered into something closer to dried persimmon than to fresh vermilion.

The Agency's register describes the structure in eight characters: sangen ikko rōmon, irimoya-zukuri, dōban-buki. Unpacked, that means a gate three bays wide with a single central passageway, roofed in the hip-and-gable form, and covered in sheet copper. The copper is a later substitution. The original covering was kokera-buki, thin overlapping shingles of split wood, which was replaced in a subsequent repair campaign.

The counting is one building. That sounds obvious for a gate, but Japanese heritage listings count structures individually, and Yoga Shrine holds three separate national listings on the same approach.

According to the Tōryū Kafu, a Ryūzōji family genealogy cited by Saga Prefecture's heritage records, Shōni Masasuke rebuilt his father's former residence as Yoga Castle in Bunmei 14 (1482) and made the shrine the guardian of the castle's northeast quarter, the direction traditionally regarded as the entry point for misfortune. The gate is said to date from around that undertaking. The shrine itself repeats this account and describes the building as late Muromachi in style.

Two Designation Dates, One Building

Search for this gate and you will find two designation years quoted with equal confidence: 1913 and 1950. Both are correct, and the discrepancy is a useful window into how Japan's heritage law developed.

In April 1913 the gate was listed under the Ancient Shrines and Temples Preservation Law of 1897 as a tokubetsu hogo kenzōbutsu, a specially protected structure. That category later became the pre-war designation of National Treasure. When the Law for the Protection of Cultural Properties took effect in August 1950, the entire pre-war National Treasure roll was reclassified as Important Cultural Properties, with a much smaller number promoted back to the new National Treasure grade. Yoga Shrine's gate moved into the Important Cultural Property class at that point.

The Agency for Cultural Affairs database records the earlier date, 14 April 1913, under designation number 00625. Saga Prefecture's cultural heritage archive records 29 August 1950. Neither is wrong; they are describing different legal moments in the same continuous protection.

Dating is the other point where sources part company. The national database assigns the gate to the Momoyama period. Saga City and the shrine both describe it as late Muromachi. A major repair recorded in Bunroku 5 (1596) falls squarely in the Momoyama range, and the structural analysis behind the national entry appears to weight the surviving fabric rather than the founding tradition. When the two conflict, the national database is the reference point, and the Muromachi attribution is best read as the date of first construction rather than of what stands today.

What earns the listing is the carpentry. The bracket sets below the encircling balcony are tsure-mitsudo, a Japanese-style arrangement; above, the brackets shift to degumi with carved kobana nose pieces. The eaves are double, with rafters spaced rather than packed. Most of the dressed timber carries the red ni-nuri finish, the latticework is black, and the exposed end grain is painted yellow ochre. The overall grammar is Japanese style, with details borrowed from the Chinese-derived karayō vocabulary that reached Kyushu through Zen temple building.

Walking the Approach

Take the sequence in order and the gate makes more sense.

The third torii, standing at the western entrance, is a Hizen torii, a regional stone form found across the old province of Hizen. It is low and broad, with the lintel and its supporting beam carved as one piece, the ends drawn out into a flowing profile, and each of the three main members assembled from three separate stones. Saga Prefecture's records give its height as 3.90 metres and the lintel length as 5.65 metres, and date it to Keichō 8 (1603), donated by Yōtaiin, wife of the Saga domain founder Nabeshima Naoshige.

Then the bridge. A gently curved stone span 10.5 metres long and 3.15 metres wide, carried on six rows of triple piers, with railings 56 centimetres high and ten bronze giboshi finials. One finial carries an inscription dated Keichō 11 (1606). The torii and bridge were designated together as a single Important Cultural Property listing on 17 June 1970, separate from the gate.

Stand under the gate and look up into the ceiling of the passageway. The framing is left exposed, and the transition from the balcony brackets to the upper storey is visible in a way that most shrine gates hide behind boarding.

To the left as you enter is a camphor tree the shrine describes as more than 1,400 years old, registered as a prefectural natural monument. Three other large camphors grow in the precinct. Behind the gate the worship hall carries a karahafu undulating gable at its front, and the main hall behind it is a five-bay nagare-zukuri; ridge tablets date them to Hōreki 8 (1758) and Hōreki 9 (1759).

Practical matters. The precinct is open ground with no admission gate and no fee, and the shrine is entered freely during daylight; the gate is walked through rather than viewed from a queue. Photography of the exterior is not restricted, though the upper storey is not open to visitors and there is no interior to tour. Yoga Shrine sits roughly two kilometres south of JR Saga Station, immediately west of the moat that borders the prefectural government offices, about a 25 to 30 minute walk or a short taxi ride. The Saga Castle Honmaru History Museum, with its Important Cultural Property Shachi-no-mon gate, is within walking distance to the east, which makes a sensible pairing for an afternoon.

A three-year conservation programme covering the gate, the third torii and the stone bridge finished in spring 2021, with re-roofing, repainting and seismic strengthening. The red you see now is recent work over old timber.
