Tsuna Shrine Main Hall

A Thatched Hall Above the Mashiko Hills

Climb the roughly one hundred stone steps that rise through the trees at Oba, in eastern Tochigi, and you reach a small wooden building under a steep thatched roof. This is the main hall of Tsuna Shrine (Tsuna-jinja), built in the three-bay nagare-zukuri style, a form in which the front roof slope sweeps down longer than the back to shelter the worship space. The national government first placed it under protection in 1916, and it holds the rank of Important Cultural Property today.

Nothing about the hall is showy. Its appeal lies in the proportions of the thatched roof, the weathered grey of the timber, and the carving tucked under the eaves.

Founded by an Exiled Warlord

The shrine's beginnings trace to Utsunomiya Asatsuna, third head of the Utsunomiya clan, who governed this part of Shimotsuke Province late in the twelfth century. In 1194 he was accused of seizing public land and banished to Tosa Province, on the island of Shikoku. Tradition holds that he prayed at the Kamo shrine in Tosa to be allowed home, and the pardon came quickly.

Back in Oba, Asatsuna retired to a family temple he had founded, Obadera, and on the slope nearby he enshrined the Kamo deity he had prayed to in exile. That act, around 1195 to 1196, is taken as the shrine's founding. The name Tsuna comes from the tsuna in Asatsuna's own name; for centuries the place was known as Tsuna Myōjin, taking its present name only after the Meiji Restoration. The enshrined deities are Ajisukitakahikone and Ōkuninushi.

One local custom still carries the memory of that hurried founding. Households here traditionally avoid putting up kadomatsu, the pine-and-bamboo New Year decoration, because the deity is said to have been installed in such haste at year's end that no one had time to prepare them.

Why It Is an Important Cultural Property

The present hall is dated by the Agency for Cultural Affairs to the middle of the Muromachi period. The shrine's own history and the Japan Heritage record place the current building a little later, rebuilt in the Daiei era (1521–1528), with an earlier reconstruction noted in 1472. The accounts agree on the essential point: what stands today is a Muromachi structure.

What earned it national protection is the quality of its carpentry and carving. The bracket complexes above the pillars use a three-block arrangement, doubled at the corners. Carved gegyo pendants hang beneath the gable, and at the offering porch the tabasami struts and kibana beam-ends are cut in a plain, vigorous manner that reads as Muromachi work rather than the more decorative styles that came later.

A three-bay nagare-zukuri hall roofed in thatch is uncommon in Tochigi, which adds to its value. The building is also one of the few surviving remnants of Obadera, the Utsunomiya family temple that has otherwise vanished.

What to Look For

Look up from the foot of the steps first. The thick, softly curved thatched roof is the building's signature, and it changes with the surrounding trees through the seasons.

Up close, the front of the hall opens into a three-bay kōhai, a covered space for offerings, carried on chamfered square posts. The main body stands on round pillars set on a continuous timber sill, while the interior pillars are cut with sixteen faces, an unusual touch. Look into the bracketing and you can read how the carpenters adjusted the heights of the blocks to keep the eaves level.

A short walk away stands a second thatched hall, the main hall of Ōkura Shrine, also an Important Cultural Property. It is a smaller one-bay nagare-zukuri building, said to date from 1527, that was later moved into this precinct as an auxiliary shrine. Near the halls grows a chinquapin tree estimated at around 800 years old, registered as a natural monument by the town and said to have been planted by Asatsuna himself. At the autumn festival, local children perform kagura sacred dance, a tradition handed down through generations.

Getting There and Nearby

Tsuna Shrine sits in the Oba district of Mashiko, a town better known for its pottery. Most visitors come by car or take a taxi from Mashiko Station on the Mōka Railway, about fifteen minutes away. There is parking at the Oba-no-sato Kōyūkan, and a first and second torii gate lead from there to the stone steps. The hall is viewed from the outside, and the climb up the approach is part of the experience.

The thatch on both shrine halls has weathered in recent years, and a local committee has been preparing a restoration, with roof work expected around 2027. Check current conditions before visiting, since access near the buildings may change while the work is under way.

The surrounding area rewards a slow walk. A few hundred metres off is Jizō-in, the temple that grew out of the old Obadera and served as the Utsunomiya family's mortuary temple; its main hall is itself an Important Cultural Property, designated on the same day in 1916 as the Tsuna Shrine hall, and the clan's graves lie close by. Farther out, Saimyō-ji temple on Mount Takadate keeps a three-storey pagoda built in 1538 and a gate of the same era, both nationally designated, along with a well-known "laughing Enma" statue. The kilns and shops of central Mashiko easily fill another half-day.
