Shinkai Sansha Shrine East Main Hall

Three main halls stand in a row on the forested rise behind the worship hall at Shinkai Sansha Shrine. The one at the far right is the smallest and the least decorated, built of plain unpainted wood beside its two vermilion-lacquered neighbours. That modest building, the East Main Hall, is the only one of the three the national government has registered as an Important Cultural Property.

It houses Okihagi-no-mikoto, the deity credited with opening the Saku basin to farming and settlement. The hall is a single-bay nagare-zukuri structure roofed in layered cypress bark, raised in the late Muromachi period, sometime between 1467 and 1572. Carpenters' marks on its members are gone, but the way its timbers are cut and joined ties it closely to the three-story pagoda that rises just behind it, dated to 1515.

A shrine of three deities, and the family behind them

The name Shinkai Sansha translates roughly as "three shrines," and the arrangement is literal. Each of the three honden enshrines one member of a single divine family. The East Main Hall holds Okihagi-no-mikoto, the chief deity. The Middle Hall enshrines his father, Takeminakata of Suwa, and the West Hall his uncle Kotoshironushi, with the warrior deity Hondawake placed alongside.

Okihagi-no-mikoto was worshipped as the pioneer ancestor of the Saku district, the leader of the people who first cultivated the floodplains of the Chikuma River and the surrounding flats. By the Heian period the shrine ranked as the regional head shrine for the Saku district, drawing the local priestly families to its festivals. Old burial mounds dot the grounds; an iron warabite-tō, a curved sword of a type carried by early eastern warriors, was unearthed from a nearby tumulus in 1965, evidence that people of standing had lived here long before.

The shrine kept powerful patrons through the medieval centuries. Minamoto no Yoritomo is said to have prayed here and ordered Hondawake, ancestral deity of the Minamoto, added to the West Hall, repairing the buildings and granting land. In 1565 Takeda Shingen offered a written prayer at the shrine before his campaign against Minowa Castle in Kōzuke. The Tokugawa and later the lords of the Tatsuoka domain continued to support and repair it.

Why the plainest hall is the protected one

Visitors often expect the grandest building to carry the highest status. Here it is the reverse. The larger West and Middle halls, with their red lacquer and crisp carvings of cranes and bamboo, are the eye-catching pair. The East Main Hall earns its national designation on quieter grounds: its age and the construction details that fix that age.

The clues sit in the kibana, the carved nosings where the horizontal tie-beams project beyond the corner posts. On the body of the hall these nosings carry a shallow relief of bamboo leaves. On the offering porch at the front, the nosings show the form just beginning to take on an animal face, an early stage in a stylistic shift that grew more pronounced in later centuries. To specialists these features place the hall firmly in the late Muromachi period and make it a useful reference point for dating shrine architecture of its kind.

Behind the East Hall stands its companion in protection, a three-story pagoda about 20 metres tall, completed in 1515 as the pagoda of the shrine's attached temple. It blends two carpentry idioms: the lowest story follows the Zen-influenced style, while the upper two follow the older Japanese style, a difference you can read in the direction the rafters run. When the Meiji government separated Buddhism from Shinto and many temple structures were torn down, this pagoda survived by being reclassified as the shrine's storehouse.

What to look for on a visit

From the wooden gate, the approach climbs north under old cedar and zelkova that throw the path into deep shade. The worship hall and the neighbouring kagura stage are built of unadorned timber, low and quiet. Walk around behind them and the mood changes at the three honden.

Stand at the far right to study the East Main Hall up close, comparing its bare cypress and shallow leaf carving against the bright lacquer of the other two. Between the West and Middle halls sits the mitamashiro-ishi, a stone pillar a little over a metre and a half high with a dragon carved on its shaft and a date corresponding to 1358. The pagoda is visible rising through the trees beyond.

At the autumn festival, usually held in early October, children from the local Taguchi elementary school perform the Urayasu-no-mai, a shrine-maiden dance set to flute and song. The shrine drew a wave of younger visitors after 2016, when the resemblance of this dance and the shrine's name to scenes in the animated film Your Name caught fans' attention. The film's director, Makoto Shinkai, comes from nearby Koumi and shares the shrine's name in writing, though the shrine is not a filming location and the link rests on coincidence rather than any official tie.

Getting there and nearby stops

The shrine sits in Taguchi, about two kilometres east of Usuda Station on the JR Koumi Line, with parking reached by the road beside the western pavilion. The three honden are roped off as objects of worship, so they are viewed from outside the enclosure rather than entered.

A short distance west lies Tatsuoka Castle, one of only two pentagonal star-fort castles built in Japan, its earthworks and moat still tracing the five-pointed plan. The Saku area is also known for its carp, served simmered in a sweet soy glaze, a local dish worth seeking out after the walk.

Q&A

QCan I go inside the East Main Hall?
ANo. All three main halls are roped off as sacred objects of worship and are seen from outside the enclosure. You can still view the East Hall's woodwork clearly from the front and side.
QWhy is the smallest, plainest hall the designated one?
AIts value lies in age and craftsmanship rather than decoration. The bamboo-leaf relief and the early animal-face nosings on its beams date it to the late Muromachi period and make it a reference example for shrine architecture of that time.
QIs this really a location from the film Your Name?
AIt is not a filming location. The shrine became a fan destination because its name matches director Makoto Shinkai's, and its shrine-maiden dance resembles a scene in the film. The connection is a coincidence that locals embraced, not an official setting.
QWhen can I see the Urayasu-no-mai dance?
AIt is performed at the autumn festival, generally in early October, by local schoolchildren after the main rites. Dates shift year to year, so check with the shrine or Saku City tourism before planning around it.
QHow do I reach the shrine without a car?
ATake the JR Koumi Line to Usuda Station; the shrine is about two kilometres east in Taguchi. A taxi or a roughly half-hour walk covers the distance, and Tatsuoka Castle lies on the way.
