Nakamaki Shrine Main Hall

A Shrine Hall with a Dated Birth Certificate

The Main Hall of Nakamaki Jinja (中牧神社本殿, Nakamaki Shrine) is a late Muromachi shrine building of 1478 at Chinonomiya in the Makioka district of Yamanashi City, Yamanashi Prefecture, designated an Important Cultural Property on 14 November 1953. It is a single structure in ikkensha nagare-zukuri form with a cypress-bark roof, and carries designation number 01251.

Most medieval shrine halls in Japan are dated by style. This one is dated by paperwork. A munafuda, a wooden tablet inscribed at the time of construction and fixed inside the roof structure, records the tenth year of Bunmei, which is 1478. Six such tablets are designated alongside the building as supplementary items. Yamanashi City's own record lists a chain of subsequent repairs, each with its tablet preserved: 1510, 1625, 1654, 1724, 1798, 1885, 1959 and 2009. Read in sequence, that is a maintenance log running five and a half centuries.

The building measures one bay at the front and one at the side, with two bays at the rear and a one-bay projecting canopy. The core is framed in round pillars, unusual enough at this scale to be worth noting, and a railed veranda runs along the front and both flanks. The gable boards break at a sharp angle, and the carved members hold a heavier, more muscular curve than the softer profiles of later centuries. Those features are what place the fabric securely in the closing decades of the Muromachi period rather than in any of the repair campaigns.

The Earth Goddess of the Makioka Villages

The enshrined deity is Haniyasu-hime, a goddess of clay and earth. In the classical myths she is born from the excrement of Izanami as the fire deity kills her, which is a violent origin for a figure who ended up presiding over soil, pottery and the fertility of fields. For an agricultural district at the foot of the Okuchichibu mountains, the choice reads as a working one rather than an ornamental one.

Kai no Kuni Shi, the early nineteenth-century topography of the province, records Nakamaki Jinja as the tutelary shrine of a group of settlements: Kubodaira, Jōkoji, Chinonomiya and Somaguchi. Four villages sharing one shrine explains something about the building. A single-bay sanctuary is a modest thing, but the resources of four communities kept it standing and kept it repaired at intervals of roughly a century, which is why a wooden structure of 1478 is still on its original site rather than known only from a record.

The designation came in 1953, in the wave of postwar assessments that swept many provincial shrine halls onto the national list. Sixteen structures in Yamanashi Prefecture carry Important Cultural Property status for shrine or temple architecture, and this is among the oldest securely dated of them.

Vineyards, a Gate, and How to Get There

The setting is the surprise. Nakamaki Jinja faces south on an alluvial fan in the northeast of Yamanashi City, and the slope around it is planted almost solidly with grapes. Makioka is Kyoho country; the variety was commercialised in this part of the prefecture, and the vine rows run right up to the edge of the shrine grove. Arriving in late summer, you walk from trellised fruit into a pocket of old cedar and cypress in the space of thirty seconds.

The precinct holds three buildings: a zuijinmon gate, a worship hall, and the sanctuary behind. The gate repays attention on its own terms. Shrine gates in Yamanashi commonly omit the cross-beam pillars to leave the front bay open, and this one keeps them, with plank brackets at the junctions of pillar and beam. Inside, the supports carrying the beams and tie-rails are carved as Chinese lions and elephants. The pillars are square with chamfered corners, topped by simple three-bracket sets, with kaerumata frog-leg struts between them and a double layer of sparse rafters overhead.

The sanctuary sits behind the worship hall and is viewed from outside, as at most shrines of this class. Nothing is ticketed and nothing is timed: the grounds are open, free, and unstaffed, with no shrine office and no one to issue a seal-stamp. Photography is unrestricted. Set aside about ten minutes for the visit itself.

Getting there realistically requires a car. The address is 576 Chinonomiya, Makioka-cho, Yamanashi City, roughly twenty minutes from the Katsunuma interchange on the Chuo Expressway. There is no dedicated car park, so plan for that in a district of narrow farm lanes. Bus services from JR Yamanashi-shi Station into Makioka are infrequent, and a taxi is the practical fallback. Combining the visit with a vineyard stop or with the Fuefukigawa Fruit Park, about twenty minutes south, makes better use of the drive.
