A Tabernacle Built in the Shape of a Shrine
Within the main hall of Sanmyo-ji in Toyokawa, behind the temple known as Toyokawa Benzaiten, stands a wooden structure about four meters tall and a single bay square. It is called a kuden, a term close in meaning to zushi, the tabernacle that ordinarily houses a sacred image inside a Buddhist hall. What sets this one apart is its form. Rather than the boxy cabinet a temple usually builds, this kuden takes the shape of a Shinto shrine's main sanctuary, a one-bay nagare-zukuri with a roof that sweeps down longer at the front, roofed in thin wooden shingles.
The structure was built in 1554 by Hongan Koetsu, a monk from the northern province of Dewa who is counted as the restorer of Sanmyo-ji. It shelters the temple's central image, a figure of Benzaiten, the deity of water, music, and fortune.
The choice of a shrine form for a Buddhist tabernacle is not idle. Benzaiten sits at the meeting point of Buddhist and Shinto worship, and the shrine-shaped kuden gives that double identity a physical shape. Few interior tabernacles in Japan take this approach.
Why the Shrine Was Designated
The kuden was listed as an Important Cultural Property in 1953. Its recorded form is a one-bay nagare-zukuri with kokerabuki shingles, the same style used for the main sanctuary of a Shinto shrine.
That is precisely the point of interest. A tabernacle inside a temple hall would normally be read as Buddhist furniture; here the carpentry borrows the grammar of shrine architecture and applies it at miniature scale. The result is a small building that documents, in wood, how flexibly medieval Japan combined its religions. Together with the temple's pagoda of 1531, the kuden makes Sanmyo-ji a rare site holding two designated buildings of such different character on one compact ground.
What to Look For on a Visit
Set expectations first. The image inside is a hidden Buddha, and the kuden is normally seen through the glass doors of the hall rather than entered. Special openings are held in January and August, when visitors can come closer to the enshrined figure.
The Benzaiten itself carries one of the region's more affecting stories. By tradition it was carved by Oe no Sadamoto, a Heian-period governor of Mikawa, in memory of a woman he loved named Rikiju-hime, made life-size in her likeness. The figure is unusual in being a bare body dressed in a layered juni-hitoe robe, and the temple changes those robes once every twelve years, in the Year of the Snake. The main hall around the shrine, rebuilt in 1712, carries a coffered ceiling painted in vivid color worth looking up to see. The temple lies about five minutes on foot from Toyokawa Station.
