Abe no Seimei- Japanese FigureMortal"Greatest Onmyōji of Japan"

The Fox's Son

Seimei's father, Abe no Yasuna, found a white fox being hunted near the Shinoda Shrine in Izumi Province and rescued it at the cost of his own injury. The fox assumed human form, took the name Kuzunoha, and nursed him back to health. They married. She bore a son.

When the boy was five or six, he glimpsed his mother's true form as she slept. A white fox, curled where his mother should have been. Kuzunoha wrote a farewell poem on a shōji screen: "If you miss me, come seek me in the Shinoda Forest of Izumi." She vanished into the trees. Her son could see things no one else could see.

The Invisible Procession

The Konjaku Monogatarishū preserves the moment Seimei's gift became known. As a young apprentice, he was riding in an ox-cart with his master Kamo no Yasunori when he spotted a procession of demons approaching on the road ahead. Yasunori saw nothing. Seimei described what was coming, and Yasunori halted the cart and pulled off the road just before the hyakki yagyō, the night parade of a hundred demons, swept past.

His reputation reached the highest levels of the Heian court. Even Fujiwara no Michinaga, the most powerful man in Japan, summoned Seimei to diagnose his ailments and determine whether vengeful spirits were responsible. The Shōyūki, the diary of the courtier Fujiwara no Sanesuke, records Seimei performing rituals on specific dates for five successive emperors, from Murakami to Ichijō, over a career spanning more than fifty years.

In another tale from the Konjaku Monogatarishū, a group of young courtiers killed a frog in Seimei's presence to test his powers. He formed a mudra, spoke an incantation, and the frog stirred back to life. The courtiers had meant to call his bluff. They did not try again.

Shikigami

Seimei commanded twelve shikigami, supernatural servants conjured through onmyōdō ritual. The household ran itself: gates opened, visitors were announced, all without a human servant in sight. His wife found their invisible presence so unsettling that Seimei hid them beneath the Ichijō Modori Bridge near his Kyoto residence. He called them when he needed them.

The Oranges and the Rats

Legends pit Seimei against Ashiya Dōman, a rival practitioner from the provinces. Dōman challenged Seimei to identify the contents of a sealed box before the court. He had placed fifteen oranges inside, confident Seimei would fail. Seimei used his power to transform the oranges into fifteen rats, then declared the box contained rats. When the box was opened and rats tumbled out, Dōman was ruined.

Later traditions describe Dōman resorting to darker methods, cursing and ultimately murdering Seimei, only for Seimei to be resurrected through the intervention of his Chinese master, the Daoist sage Hakudō.

The Seimei Shrine

Seimei died in 1005 at eighty-five. Two years later, Emperor Ichijō ordered a shrine built on the site of his former residence in Kyoto, enshrining the onmyōji as a kami. His emblem, the five-pointed Seimei star (晴明紋), became the shrine's crest, stamped on lanterns, tiles, and the main well cover throughout the grounds. The Ichijō Modori Bridge where he had hidden his shikigami became a site of folklore in its own right.
