Main Hall of Furukuma Shrine

A Shrine Hall That Changed Address in 1618

The Main Hall of Furukuma Shrine (古熊神社本殿, Furukuma-jinja Honden) in Furukuma 1-chōme, Yamaguchi City, Yamaguchi Prefecture, is a three-bay shrine hall of Muromachi-period workmanship that was re-erected on its present site in 1618, and it was designated an Important Cultural Property on 13 August 1917.

The shrine did not begin here. In 1373, Ōuchi Hiroyo, the warlord who laid out Yamaguchi on the model of Kyoto, brought the spirit of Kitano Tenmangū down from the capital and installed it at Kitano-kōji, one of the streets in the town he was building. Two and a half centuries later Mōri Hidenari, first lord of the Chōshū domain, had the halls dismantled and reassembled at Furukuma, on the eastern edge of the city. The record gives the fourth year of Genna, 1618, for that move.

Which leaves the building with two dates attached to it. They do not agree.

The Agency for Cultural Affairs database enters the Main Hall under Genna 4 (1618), the year of the relocation. Yamaguchi Prefecture and Yamaguchi City both treat the timber itself as medieval. Their case rests on an ink inscription reading Tenbun 16 (1547) on a board of the kūden, the miniature shrine housed inside the hall; some specialists read the joinery and the profile of the frog-leg struts as pointing a few decades earlier still, to the middle of the Muromachi period. Visitors will see the later date on the national database and the earlier reading on the interpretive board in the precinct. Both are recorded positions, and the shrine has never claimed to settle the question.

After the move the shrine was known as Ima-Tenjin, "the new Tenjin." It took the name Furukuma Shrine in 1873. Locally it goes by neither: people say Yamaguchi no Tenjin-sama, the Tenjin of Yamaguchi.

Sugawara no Michizane, the ninth-century scholar-official deified as the patron of learning, is the principal deity. Beside him is his son, Sugawara no Fukube Dōji, who is said to have set out at eleven to follow his exiled father toward Dazaifu and to have died of summer fever in Suō Province, the old name for this part of Yamaguchi, in 902.

Why the Main Hall Carries National Designation

The hall measures three bays across the front, about 5.67 metres, and two bays deep, about 4.13 metres. It stands a single storey high under an irimoya roof, the hipped-and-gabled form, covered in hiwadabuki: strips of cypress bark laid by hand in overlapping courses and trimmed to a soft, slightly rounded edge.

That roof is the point.

Shrine main halls in this part of the country almost always use nagare-zukuri, in which one slope of a plain gable runs forward over the steps to shelter the person standing below. Yamaguchi City holds three other main halls of comparable age, at Hirashimizu Hachimangū, Imahachimangū and Yasaka Shrine, and all three follow that pattern. Furukuma's does not. An irimoya roof over a three-bay shrine hall belongs to the vocabulary of Buddhist temple carpentry, and its appearance here is read as evidence of how thoroughly temple builders' habits had worked their way into shrine construction by the fifteenth and sixteenth centuries.

The second reason follows from the first. The Main Hall does not stand free. It is physically joined to the worship hall in front of it, and prefectural heritage staff describe the resulting linked plan as an early step toward gongen-zukuri, the connected main-hall-and-worship-hall arrangement that became standard in the Edo period and is best known from the mausolea at Nikkō. Furukuma's version runs a century or more ahead of those.

Designation came early. The listing dates to 1917, the sixth year of Taishō, within the first decades of Japan's system for protecting historic buildings, and at a point when the pine-bamboo-plum carvings were already well known to architectural historians. The kūden inside was added to the designation on 3 February 1979, so the official entry now reads "Main Hall of Furukuma Shrine, with kūden."

The Carvings on the Front Beam

Three kaerumata sit along the front of the Main Hall. A kaerumata, literally "frog legs," is a curved strut set on a horizontal beam, splayed at the base like a squatting frog. By the medieval period its open centre had become a field for carving, and Japanese carpenters filled it with foliage, birds and family crests.

These three carry pine, bamboo and plum, one motif to each strut, with the Ōuchi family's diamond crest worked into the plum panel at the centre. Accounts differ slightly on which of pine and bamboo takes the left and which the right, and one description pairs each with a phoenix. What is not in dispute is the claim made by the prefectural cultural properties office: no older architectural use of the pine-bamboo-plum trio survives anywhere in Japan.

The combination arrived from China as the Three Friends of Winter, a set of literati emblems for endurance through cold. In Japan it drifted over the centuries into something else entirely, a three-tier grading system that still appears on sushi menus and gift catalogues. Finding it carved on a shrine of the fifteenth or sixteenth century, before any of that had happened, resets the scale of the thing. The Ōuchi are the reason it is here. Their trade with the continent gave them access to Chinese taste well ahead of most of Japan, and Yamaguchi under their rule absorbed Kyoto's fashions at a speed that Kyoto itself, wrecked by the Ōnin War, could not sustain. Whatever pine-bamboo-plum carving once existed in the capital burned.

Look at the roof surface as well. The cypress bark is not old. Through much of the twentieth century the hall stood under copper sheeting, and hiwadabuki was restored in 1996. Cypress bark weathers from warm brown toward silver-grey across a thirty- to forty-year cycle, so the roof reads differently depending on the decade in which you happen to see it.

You do not go inside. The hall is viewed from the front, across the floor of the joined worship hall, and from the flanks, where the ground falls away far enough to let you read the section of the roof and the depth of the eaves. The kūden stands within and is not shown.

Getting There, and When to Come

The precinct is open at all hours and there is no admission charge. Furukuma Shrine is a working shrine rather than a managed monument, and the Main Hall comes into view the moment you reach the top of the steps.

The shrine's own directions give fifteen minutes on foot from JR Yamaguchi Station, or three minutes by taxi. Kami-Yamaguchi Station, one stop further along the Yamaguchi Line, is a comparable walk and marginally closer as the crow flies. Around twenty parking spaces sit at the top of the slope that climbs past the torii, though the approach is narrow and awkward for larger vehicles.

Photography of the exterior is not restricted. Amulets and goshuin seal-stamps are issued at the shrine office partway up the steps, and the shrine asks that requests not be made after dark; the office also handles stamps for Noda Shrine and Toyosaka Shrine in the same city. Formal prayers are booked in advance and received between 8:00 and 17:00.

February and early April are the two moments worth planning around. The precinct is known locally for its plums, appropriate for a shrine of Michizane, who wrote about the plum tree of his Kyoto garden on his way into exile, and for cherry blossom a few weeks after. Late November brings the Yamaguchi Tenjin Matsuri, when the quiet of the site disappears entirely for three days.
