A hall of 1820, with the hills at its back
Ryusenji Temple Main Hall (龍泉寺本堂, Ryūsenji Hondō) is a Buddhist worship hall in the Idezawa district of Shinshiro City, Aichi Prefecture, built in 1820 and entered on the national register of Tangible Cultural Properties on 24 December 2013. It stands near the centre of the temple grounds, facing south, with wooded slopes rising close behind it and the Toyokawa River running below.
The temple's own records place its founding in 1558 under a different name, Kōshakuji. It became Takigawaji in 1606 and Ryūsenji during the Kan'ei era, between 1624 and 1644. The hall you see is far younger than the institution that owns it, a late Edo-period rebuilding raised in the third year of the Bunsei era.
Ryusenji Temple Main Hall measures roughly 10 metres by 12 metres and covers 124 square metres. The roof is Irimoya-zukuri, gabled above and hipped below, laid with Sangawara-buki pantiles. Walls are Shikkui lime plaster held between exposed posts and beams, the Shinkabe method that leaves the timber frame visible from outside.
Five buildings, one day on the register
The hall carries registration number 23-0385, listed under the criterion of contributing to the historic landscape of the country. The distinction matters: National Treasures and Important Cultural Properties are designated under the Law for the Protection of Cultural Properties, while the Registered Tangible Cultural Property scheme, created in 1996, registers buildings that remain in everyday use. Ryusenji Temple Main Hall belongs to the second category.
Four neighbouring buildings joined the register on the same day in December 2013: the founder's hall and memorial tablet hall, the Kannon hall and tea hall, the priests' quarters and the bell tower. Between the main hall of 1820 and the bell tower of 1955 lie 135 years of piecemeal building, and it is the group as a whole that the listing recognises.
Three more registrations were made in Shinshiro that day, all within a few kilometres: two structures at Yahira Shrine in the same Idezawa district, and the main hall of Taki Shrine in neighbouring Ōmi. The Takigawa Family Residence in Idezawa, with a gatehouse of 1763, was registered earlier and is privately owned.
Through the roji to the inner sanctuary
A curved rainbow beam, Kōryō, spans the central bay of the front elevation. Anyone admitted inside climbs a wooden stair and arrives in a zone the temple calls the roji, then moves into the ōma, the wide outer chamber, and finally faces the Naijin, the inner sanctuary.
The plan is a grid of six rooms with a broad veranda across the front. Low partition walls and a takenofushi transom split the ōma into a centre and two flanks. That transom is worth a pause: slender posts notched to look like bamboo joints, horizontal rails above and below, and diagonal lattice filling the gaps.
At the rear of the middle row stands the Shumidan, the tiered altar platform. Round columns mark the threshold to the ōma, tied by carved rainbow beams, and the Ranma above them carry cloud dragons and Chinese lions. Against the flat white plaster, the shadows in the carving read clearly even in dim light. For a temple this deep in the valley, the ambition of the woodwork comes as a surprise.
Planning a visit
Ryūsenji is a working parish temple owned by a religious corporation, not a museum. No opening hours and no admission fee have been published as of September 2026, and there is no visitor reception. The exterior can be seen from the grounds; going inside, or photographing the interior, calls for a phone call to the temple beforehand, and services are held on some days.
By train, Ōmi Station on the JR Iida Line is the closest stop, about 2.7 kilometres to the southeast, which is a walk of roughly 35 minutes. Trains on this line are infrequent, so check timetables before setting out. Drivers can reach the temple in about 10 minutes from the Shinshiro interchange on the Shin-Tōmei Expressway, a distance of some 7 kilometres.
Questions about the registered buildings can also go to the History and Culture Division of the Shinshiro City Board of Education on 0536-23-7610. The division's website carries interior photographs of the hall.
