Saienji Temple Main Hall

A Buddhist Hall with Sash Windows

Saienji Main Hall (西圓寺本堂, also written Saien-ji Hondō) is the main worship hall of a Jōdo Shinshū temple at Oezuka in Kamojima, Yoshinogawa City, Tokushima Prefecture, completed in 1932 and entered on Japan's register of Tangible Cultural Properties on 4 August 2015.

Approach it from the north, walking the four hundred metres or so down from Oezuka Station, and the first thing you register is the wall. It is clad in horizontal boards, lapped like the siding on an American farmhouse, and punched with double-hung sash windows that slide vertically in their frames. Neither belongs to the vocabulary of Japanese Buddhist architecture. Above them the roof is entirely conventional: tiled, hipped-and-gabled, entered on its long side in the manner of every Shin Buddhist hall in the country.

The building is a single storey of timber covering 222 square metres, and it is composed of two joined volumes that behave differently. The rear portion, containing the naijin or inner sanctuary where the image of Amida Buddha is enshrined, keeps the standard Japanese profile. The front portion, the gejin where the congregation gathers, is where the design departs. Its gable end facing the street has been clipped, cut back at the apex into what Japanese carpenters call a hankirizuma and English-speaking builders call a jerkinhead, and a carriage porch projects from the centre of the front to shelter arrivals.

The result is a Buddhist hall that looks, from certain angles, like a small provincial chapel or a rural school. That was not an accident.

The Priest Who Went Abroad

The record kept by the Agency for Cultural Affairs is unusually explicit about motive. The head priest at the time had travelled overseas, and on his return he argued for a Buddhist hall in which worshippers would sit on chairs. The Western detailing on the outside follows from that argument rather than preceding it.

To see why this mattered, it helps to know what a Shin Buddhist hall normally is. The gejin is a tatami floor. Congregants kneel on it, in rows, facing the altar. The posture is part of the practice and the flooring is part of the building. Replacing it with fixed seating changes the floor construction, the ceiling height, the sightlines and the way light needs to enter, which in turn pushes the designer toward larger windows in the side walls. Sash windows in a weatherboarded wall are the practical answer to a liturgical decision.

Japan's Buddhist establishment was arguing about exactly this in the 1920s and 1930s. Tsukiji Hongwanji in Tokyo, the best-known product of that debate, was rebuilt in 1934 to designs by the architectural historian Itō Chūta, using reinforced concrete and an exterior drawn from ancient Indian Buddhist building. Saienji went up two years earlier, in a country town on the Yoshino River, in wood, at a fraction of the budget. It is the more modest building by any measure and in one respect the bolder one, because Itō kept the traditional Shin hall arrangement inside his exotic shell while the Tokushima priest went after the seating.

The Agency's assessors called the form dokusōteki, meaning original or inventive, which is not language they use casually. Registration came in the eighty-first round, under the criterion covering buildings that contribute to the historical landscape of the country, with the registration number 36-0127.

The name of the priest who proposed the change does not appear in the national record, and no published local source consulted for this article supplies it. Anyone researching the building further would want to start with the temple itself or with the Yoshinogawa City board of education.

Seeing It, and the Country Around It

Saienji is a working parish temple, not a museum. The precinct can be entered and the exterior of the hall studied from within it, but the interior is used for funerals, memorial services and the temple's regular observances, and there is no scheduled public opening. Anyone hoping to see the gejin and confirm how the seating was handled should telephone in advance on 0883-24-0835 and ask. The same applies to photography inside; the exterior can be photographed freely from the grounds.

Getting there is easier than the rural address suggests. Oezuka Station on the JR Tokushima Line sits almost directly north of the temple, close enough that the walk takes about five minutes on flat ground. It is an unstaffed station served only by local trains, so check the timetable before committing. Kamojima Station, two stops east, has more services and is a reasonable taxi base.

The wider setting is worth a little of your time. This stretch of the Yoshino River plain was indigo country. The dyestuff made from Persicaria tinctoria grown on these flood plains supported merchant families through the Edo and Meiji periods, and the story of that trade was recognised in 2019 as a Japan Heritage narrative titled Ai no Furusato Awa, the homeland of indigo. Yoshinogawa City maintains a published list of its designated and registered cultural properties, which is the place to look if you want to build a day around Saienji rather than a single stop.

One footnote for anyone cross-checking the paperwork. The Agency for Cultural Affairs record names the owner as the religious corporation Saienji but classifies the owner type as an educational corporation. The two entries do not agree, and the temple's own status as a Jōdo Shinshū Hongwanji-ha parish makes the religious-corporation entry the credible one.
