Eijuji Kaisando and Ihaido: The Hall Where a Zen Temple Honors Its Founder
Step behind the main hall of Eijuji, a Soto Zen temple in the city of Shinshiro, Aichi Prefecture, and the ground plan shifts from worship to remembrance. A long gabled wing runs north to south, and inside it two rooms sit one behind the other. The front room is the Kaisando, the hall of the founding priest. The room continuing beyond it is the Ihaido, where the memorial tablets of the temple's dead are kept. Together they form a single registered structure completed in 1893, the most recent of Eijuji's surviving monastic buildings.
The pairing is not decorative. In a Soto monastery the founder is venerated almost as a living presence, and the dead of the parish are gathered close to him. Placing the two halls along one axis, joined under one roof, gives architectural form to that idea of continuity between the founder and the generations who followed.
A Meiji-Period Building in an Older Complex
Eijuji traces its origins to 1513, when it was established under the patronage of the local lord Suganuma Sadahiro. The temple was burned during the warfare of 1573 and rebuilt at its present site in Urano in 1574 by Okudaira Sadayoshi. Over the following centuries successive lords of Shinshiro, including Mizuno Wakenaga, rebuilt and added to the halls.
The Kaisando and Ihaido belong to a later chapter. They date from 1893, the twenty-sixth year of the Meiji era, a time when the temple was renewing its older fabric. The building is single-storey timber construction with a tiled roof and a floor area of about 107 square metres. It stands directly north of the main hall, connected to it, so that a worshipper moving from the main hall toward the founder's seat passes through a deliberate sequence of spaces rather than crossing open ground.
What to Look for Inside
The front Kaisando is two bays deep. Round pillars carry a curved tie-beam shaped like a kamoi lintel across the front, and a triple set of rainbow beams, the curved beams Japanese carpenters call koryo, spans the space before the altar. At the centre of the altar a cusped opening, the flame-shaped katoguchi profile borrowed from Zen architecture, frames a projecting Buddhist niche. The effect is to draw the eye toward the seat reserved for the founder.
The Ihaido behind it is far deeper, running seven bays. Tiers for memorial tablets line both the east and west walls, and high windows above them let light fall onto the lacquered ranks of tablets. The contrast between the compact, focused founder's hall and the long, light-filled tablet hall is the building's quiet drama, and it rewards a slow walk from one end to the other.
Why It Was Registered
In 2019 the hall was entered on Japan's register of Tangible Cultural Properties under the criterion of serving as a model of its building type. This is a lighter form of protection than designation as a National Treasure or Important Cultural Property, and it recognises buildings that are well made and characteristic rather than singular masterpieces. What gives the Kaisando and Ihaido their value is less the individual hall than its place in a rare survival: Eijuji keeps an almost complete set of the buildings a Soto training temple once needed, and the founder's and memorial halls are an integral part of that ensemble.

Q&A
- What is the difference between the Kaisando and the Ihaido?
- The Kaisando, at the front, enshrines the temple's founding priest and is the focus of his veneration. The Ihaido behind it holds the memorial tablets of the temple's deceased, arranged in tiers along the side walls. The two share one roof to express the bond between the founder and later generations.
- When was the building constructed?
- It was completed in 1893, during the Meiji era, making it the newest of Eijuji's registered monastic structures. The temple itself was founded much earlier, in 1513.
- What designation does it hold?
- It is a Registered Tangible Cultural Property, added to the national register in December 2019. Registration is a lighter-touch system than the designation given to National Treasures and Important Cultural Properties.
- Can visitors go inside?
- Eijuji is an active temple, and the founder's and memorial halls are used for services rather than kept open for sightseeing. The precinct can be visited, but interior access to this building is limited, so it is best to contact the temple in advance if you hope to see it.
- How do I reach Eijuji?
- The temple stands in central Shinshiro, reached on the JR Iida Line. From Shinshiro Station it is a short distance to the Urano district where the temple grounds lie.
