Mitsuzoin Tahoto Pagoda

The Mitsuzoin Pagoda: A Zen Silhouette on an Esoteric Form

The two-storied pagoda at Mitsuzoin carries a quiet contradiction in its timber. A tahoto of this kind belongs to the esoteric world of Tendai and Shingon Buddhism, yet the carpenters who raised it borrowed the Zen architectural vocabulary that had arrived from Song-dynasty China, giving the eaves a crisp upward sweep at the corners. Built in the middle of the fifteenth century, it is the only medieval structure left standing on the grounds of a temple that once controlled more than 700 branch temples across eleven provinces.

Today the pagoda sits in a hushed compound on the eastern edge of Kasugai, in Aichi Prefecture, where most visitors find themselves alone with it. The surrounding halls that once made this one of the great Tendai centers of Owari Province are gone. The pagoda remains, and it is worth the trip.

A Temple That Once Ranked Among the Largest in Owari

Mitsuzoin was founded in 1328 by the monk Jimyo Shonin, who gave it the full name Io-zan Yakushi-ji Mitsuzoin. As a branch of Enryakuji, the head temple of the Tendai school on Mount Hiei, it held the intermediate rank of chu-honji, a regional headquarters. Jimyo transmitted the Yojo lineage of esoteric initiation here, and at the temple's height the precinct held thirty-six sub-temple cloisters and more than 3,000 monks in training. Pilgrims came from across central Japan to receive rank and ordination.

That reach did not last. During the wars of the sixteenth century, Oda Nobunaga's campaign against Enryakuji rippled out to its affiliated temples, and Mitsuzoin declined sharply, its branch temples falling to around a hundred. A revival came in 1615, when Chinyu, a senior monk of the Yojo lineage, moved to Mitsuzoin and rebuilt its principal halls. He later served as administrator of the Tosho-gu shrine within the third bailey of Nagoya Castle.

Because the temple conferred clerical rank rather than relying on a base of parishioner households, its finances grew precarious after the Meiji reforms of the late nineteenth century. The Nobi Earthquake of 1891 toppled the main hall, the Nio gate, and the initiation hall. By the 1930s a single sub-temple survived. The pagoda came through all of it.

Why the Pagoda Is an Important Cultural Property

A tahoto is a distinctively Japanese pagoda type: a square lower story, a white plastered transition that swells outward like a dome, and a cylindrical drum above carrying a square pyramidal roof and a tall bronze finial. The form honors Tahonyorai, the Buddha of Abundant Treasures, who in the Lotus Sutra appears inside a jeweled stupa to confirm the teaching of the historical Buddha. Tahoto were favored above all by the esoteric schools.

What makes the Mitsuzoin pagoda unusual is its styling. Rather than the native Japanese manner most esoteric pagodas follow, its builders adopted Zen-style detailing, the system of bracketing and proportion that monks and craftsmen brought from China in the Kamakura period. The clearest sign is the roofline, which lifts sharply toward each corner instead of running level. The structure is a three-bay tahoto, meaning each side of the lower story is divided into three sections, and it is roofed in kokerabuki, thin overlapping shingles of split wood rather than tile. It rises to roughly 16 meters.

The national government recognized the building as an Important Cultural Property on April 15, 1920, one of the earlier such designations in the prefecture. Five wooden ridge tablets, the munafuda recovered from the structure, are protected together with it as attached items; these inscribed boards are the kind of evidence that lets specialists date and document a building's construction and repairs.

What to Look For When You Visit

Stand a little back from the pagoda and watch the eaves. The upward curl at the corners is the detail that gives the building its Zen character, and it reads differently as the light moves across the day. The shingled roof, soft gray and slightly furred where the wood has weathered, sits against the white band of the lower transition in a way that tile could never reproduce.

The pagoda is the centerpiece, but the temple holds far more than one treasure. Its principal image, a wooden standing figure of Yakushi Nyorai, the Buddha of healing, is also an Important Cultural Property; it is kept as a hidden image in a storehouse and is not normally on view. In all, twenty-nine designated cultural properties belong to the temple, including a provincially designated Tosotsuten mandala and a portrait of the founder Jimyo.

One day a year opens the doors. On the first Sunday of October, Mitsuzoin holds a public showing of its stored treasures, when paintings of the Buddha and Kannon ranging from the Heian to the Edo periods come out of the dark. In summer the pagoda is sometimes lit after dusk, and the shingled roof takes on a different mood under the lights.

Around Mitsuzoin

Kasugai rewards a slower visit. The city is closely tied to Ono no Michikaze, one of the three great calligraphers of the Heian court, and the Tofu Memorial Hall presents his legacy alongside changing exhibitions of brushwork. Two other temples worth pairing with Mitsuzoin are Enpuku-ji and the shrine of Utsutsu-jinja, both within the city.

For green space, Ochiai Park offers water and walking paths, while Futagoyama Park preserves a sixth-century keyhole-shaped burial mound. Kasugai also has an unexpected specialty: it is a long-standing center of cactus cultivation, a quirk that turns up in local shops and dishes for anyone curious enough to look.
