Ashiya Dōman

Ashiya Dōman (ja. 蘆屋道満, spelled also 芦屋道満), also known as Dōma Hoshi (道摩法師) was an onmyōji who lived during the Heian period, in the reign of the Emperor Ichijō. The year of birth and death is unknown.[1] Despite being generally known as Ashiya Dōman nowadays, that name is unknown in the literature of the time when he was said to have been active. In addition, there are many unclear points about the real image, such as the theory that regards Dōma Hoshi and Dōman Ashiya to be different men. There is a record that "there was an onmyōji named Dōman in the Heian period, and he was hired by a noble woman named Takashina no Mitsuko (高階光子), aunt of Fujiwara no Korechika"[2] According to Harima Kagami, which was a topography of the Edo Period, he was from Kishi village in the Harima Province (present day Nishikankicho Kishi, Kakogawa, Hyōgo).

In most of the literature up to Edo Period, he is portrayed as having a rivalry with Abe no Seimei (considered the founder of Onmyōdō), being the "evil Dōman" (悪の道満) counterpart to the "Seimei of justice" (正義の晴明). He had power of jujutsu in no way inferior to that of Seimei. Being finally defeated by Seimei in a fight using shikigami, Ashiya Dōman was exiled to Harima Province. While Abe no Seimei was an onmyōji who was employed by Fujiwara no Michinaga, Dōman was an onmyōji who was employed by Fujiwara no Akimitsu. Akimitsu had a huge grudge against Fujiwara no Michinaga, because his daughter Enshi was the wife of the next Emperor of Japan, Prince Atsuakira, until the Prince abandoned her and their son to marry Michinaga's daughter. Legend says that the despair caused Enshi to fall ill and die, and so Akimitsu commissioned Ashiya Dōman to hex Michinaga. A curse caused all of Michinaga's daughters to die in quick succession, and the people who feared Akimitsu for what they assumed to be his divine power started calling him "Demonic Minister of the Left". There are also claims that a relative of Korechika, Takashina no Mitsuko, attempted to get Michinaga hexed, and was arrested for that.[2]

As the legend of Abe no Seimei spread, so did the legend of Dōman, and he has many alleged burial mounds (kubizuka) remaining in various parts of Japan. Also, Shoganji Temple in Nishikankicho Kishi in Kakogawa preserves the legend of Ashiya Dōman.

Legends about Dōman were later dramatized for Jōruri and Kabuki, with the play Ashiya Dōman Ōuchi Kagami, written by Takeda Izumo I in 1734, being one of the most popular to this day. However, after the Meiji era, the performance of the third act, in which Dōman is an important character, became rare, so it became difficult to understand why the work was named after him. When performing this work in Kabuki, there are many cases where only the 4th act is performed, and it is sometimes called "Kuzunoha" (Dōman is only a minor character there). In the play, the sudden death of a court astrologer Kamo no Yasunori causes a succession battle between Abe no Seimei's father, Abe no Yasuna, and Ashiya Dōman. In the final scenes of the play, there is a contest of magic between Seimei and Ashiya Dōman, with Seimei finally inheriting the astrological duties.[3]
