Yamada Tenmangū — 山田天満宮

Yamada Tenmangū was built in 1672 not for students, but for a castle. Lord Tokugawa Mitsutomo commissioned it as a spiritual guardian for Nagoya Castle’s northeastern direction — the kimon, or “demon gate” through which misfortune was believed to enter. He chose Sugawara no Michizane, the deified scholar, not for his association with learning but for his reputation as a wrathful protector. The shrine sits in Nagoya’s Kita Ward, a modest compound with a peculiar feature: a separate sub-shrine to Mitoshi-no-Kami, the kami of wealth, where visitors wash coins and bills in sacred water — a ritual that has made this Tenmangū as much about fortune as scholarship.

Yamada Tenmangū was established in the fourth year of Kanbun (1672) during the early Edo period. Tokugawa Mitsutomo, second lord of the Owari Tokugawa domain, faced a geomantic problem: Nagoya Castle’s northeastern approach — the traditional direction of demonic entry in Chinese cosmology — lacked spiritual defense. He ordered the construction of a Tenman shrine dedicated to Sugawara no Michizane, whose angry spirit had once terrorized the imperial court in Kyoto. The shrine’s original purpose was apotropaic, not educational. During the Meiji period, the shrine absorbed elements of folk worship, including the Mitoshi Shrine dedicated to agricultural and commercial prosperity. The current buildings date from post-war reconstruction, the originals having been destroyed in the 1945 air raids that devastated Nagoya.

Sugawara no Michizane (845–903 CE) is the primary deity, worshipped under the name Tenman Daijizai Tenjin. A scholar-courtier of the Heian period, Michizane excelled in Chinese poetry and rose to high rank before being exiled to Kyushu through political conspiracy. He died in exile, and a series of disasters in Kyoto — lightning strikes, plagues, deaths of his enemies — were attributed to his vengeful spirit. Enshrining him transformed rage into protection. At Yamada Tenmangū, he serves dual functions: guardian against directional misfortune and patron of learning. The shrine also houses Mitoshi-no-Kami, an agricultural kami associated with the rice harvest who evolved into a deity of commercial success. Michizane’s messenger is the ox, and a stone nadeboshi (stroking ox) statue stands in the precincts where visitors rub its head for academic improvement.

The Coin-Washing Spring

The Mitoshi Shrine within Yamada Tenmangū contains a small spring called Kinsen-sui (Money-Washing Water). Local tradition holds that money washed in this sacred water and then spent will return multiplied. The practice derives from a merchant family in the early 1900s who credited their prosperity to washing their first sale’s coins at the shrine before using them to purchase new stock. The ritual became formalized: visitors place bills and coins in provided baskets, rinse them under the spring water, dry them with white cloths, and carry them in their wallets until spent. Unlike the more famous Zeniarai Benzaiten in Kamakura, which promises multiplication if the money is saved, Yamada’s teaching is circulation — wealth flows through spending, not hoarding.

The shrine follows a compact urban layout, rebuilt in reinforced concrete after 1945 but maintaining traditional nagare-zukuri roof forms. The main hall (honden) is modest in scale, appropriate to a domain shrine rather than a grand pilgrimage site. The prominent feature is the vermilion shrine gate leading to the Mitoshi sub-shrine, which sits to the left of the main worship hall. The Kinsen-sui spring is housed in a small wooden pavilion with bamboo ladles and draining baskets. A large plum tree grows near the main hall — plum blossoms being Michizane’s emblem, from the poem he composed when exiled: “When the east wind blows, send me your fragrance, plum blossoms.” The shrine grounds include a small garden with the nadeboshi ox statue, its horns worn smooth by generations of hands.

• Hatsu-Tenjin (January 25) — The first Tenjin day of the year, when students and parents come en masse to pray for entrance exam success. The shrine sells ema (wooden prayer plaques) shaped like plum blossoms.
• Plum Blossom Festival (Late February to Early March) — A modest celebration when the shrine’s ume trees bloom, with calligraphy demonstrations and tea ceremony in honor of Michizane’s scholarly arts.
• Nagoshi-no-Harae (June 30) — The mid-year purification ritual, featuring a chi-no-wa (reed ring) through which visitors pass to cleanse half a year’s accumulated impurities.
• Autumn Festival (October 25) — The main annual festival with mikoshi procession through the surrounding neighborhood, though on a smaller scale than major Nagoya shrines.

Late February to early March during plum blossom season. The shrine is quietest on weekday mornings, allowing unhurried access to both the main hall and the Mitoshi coin-washing ritual. January should be avoided unless you specifically want the crush of entrance exam season — the 25th brings thousands. The autumn colors in early November provide pleasant surroundings, though the shrine’s urban setting means limited foliage. For those interested in the money-washing ritual, weekday afternoons offer the most privacy to perform it without a crowd watching.
