Two Precincts, Seven Buildings
Suwa Taisha Shimosha (諏訪大社下社), the Lower Shrine of Suwa Taisha in Shimosuwa Town, Nagano Prefecture, has two precincts, Harumiya and Akimiya, whose seven worship buildings, built in the An'ei era and in 1835, were designated an Important Cultural Property in 1983.
Suwa Taisha straddles Lake Suwa: the Upper Shrine (Kamisha) lies to the south and the Lower Shrine to the north. The two precincts of Suwa Taisha Shimosha stand along the old Nakasendo highway. Harumiya, the Spring Shrine, is about 1 kilometer northwest of JR Shimo-Suwa Station; Akimiya, the Autumn Shrine, is about 1 kilometer east of Harumiya and roughly a 10-minute walk from the station. The deities move between the two every six months, in ceremonies held each February and August.
The designation covers three buildings at Harumiya (the heihaiden and its left and right side worship halls) and four at Akimiya (the same three plus the kagura hall). Neither precinct has a honden, or main sanctuary. Behind each heihaiden stand two treasure halls, and beyond them a sacred tree, a cedar at Harumiya and a Japanese yew at Akimiya, which serves as the focus of worship.
Why the Lower Shrine Buildings Matter
The seven buildings are protected as an Important Cultural Property. According to Japan's Agency for Cultural Affairs, the layout of the heihaiden and side halls at Suwa Taisha Shimosha broadly follows the Upper Shrine's Honmiya. The difference is that the offering hall and the worship hall, separate buildings at Honmiya, are combined here into a single two-story gate-like structure, a form particular to the Lower Shrine. Harumiya and Akimiya share the same basic plan and differ in details.
What sets them apart is who built them. The Agency attributes Harumiya to Shibamiya Chozaemon of the Osumi school, heirs to the Suwa domain's official carpenters, and Akimiya to Tatekawa Washiro Tomimune, founder of the Tatekawa school. Two rival local workshops staked their reputations on these buildings, and the carving is the result.
The shrine says the Suwa domain seems to have handed both workshops the same set of drawings, so the buildings share a structure though not a size. Harumiya, it adds, was started later but finished a year earlier.
The dates vary by source. The national database gives the eighth year of An'ei for the three Harumiya buildings and 1780 for the three Akimiya buildings. The shrine, for its part, dates the completion of Harumiya to 1780 and Akimiya to the spring of 1781.
Each heihaiden is one bay wide and two deep, built as a two-story gate with a gabled roof (Kirizuma-zukuri), a curved karahafu eave over the front (Noki-karahafu) and copper-sheet roofing (Dōban-buki). The side halls show another contrast: those at Harumiya are 5 bays by 1 bay under a single-pitch roof, while those at Akimiya are 5 bays by 2 bays with gabled roofs.
What to Look For at Suwa Taisha Shimosha
The Akimiya kagura hall
Pass through the torii at Akimiya and the kagura hall fills the view, hung with a giant shimenawa rope. It was built in 1835 by Tatekawa Washiro Tomimasa, the second-generation master who also built the worship halls at the Upper Shrine's Honmiya. The hall is 5 bays by 3, with a T-shaped gabled roof entered from the gable end (Tsumairi), so it presents a gable on three sides. The rope, remade for every Onbashira festival, is about 13 meters long and is estimated by the shrine to weigh 500 kilograms.
Comparing the carvings
Behind the kagura hall rises the Akimiya heihaiden, a two-story gate with side halls stretching out to either side. The shrine presents its carvings as Tomimune's masterwork. If you walk on to Harumiya, stand in the same spot there and compare Shibamiya Chozaemon's work. Because the frames are the same, the differences in composition and density of the carving are easy to read.
Harumiya
Harumiya repeats the sequence: a kagura hall facing the approach, with the heihaiden and side halls behind it. The Harumiya kagura hall is not part of the designation, and since the three listed buildings stand behind it, step to one side to see them as a group.
Visiting Suwa Taisha Shimosha
Neither precinct of Suwa Taisha Shimosha closes its gates, so you can enter at any hour, and admission is free. The amulet office at Harumiya is open 8:30 a.m. to 4:30 p.m., and the one at Akimiya 8:30 a.m. to 5:00 p.m. The Akimiya treasure museum opens 9:30 a.m. to 3:00 p.m. The seven designated buildings are viewed from outside; the interiors are not open.
The shrine prohibits drones on its grounds. Publishing photographs in print or online requires an application to the public relations office at Akimiya.
