Taira no Masakado (平将門, died March 25, 940) was aHeian period provincial magnate (gōzoku) andsamurai based ineastern Japan, notable for leading the first recorded uprising against the central government inKyōto.[1] Along withSugawara no Michizane andEmperor Sutoku, he is often called one of the “Three Great Onryō of Japan [ja].”.[2]
Masakado was one of the sons ofTaira no Yoshimasa (平良将), also known as Taira no Yoshimochi (平良持),[3][a] of the KanmuTaira clan (Kanmu Heishi), descendants ofEmperor Kanmu (reigned 781–806) who were demoted from princely to commoner status and granted the Taira surname. Yoshimochi[b] was one of the sons ofPrince Takamochi, a grandson or great-grandson of Kanmu who was appointed the vice-governor ofKazusa Province (modern centralChiba Prefecture) in 889 (Kanpyō 1). Takamochi's sons who joined him there occupied a variety of provincial offices in the eastern part of the country such as that ofchinjufu shōgun, thecommander-in-chief of the defense garrison (chinjufu) inMutsu Province tasked with subjugating theEmishi peoples of the north.[9][10][11][12][13]
Not much is known of Masakado's birth and early life due to lack of written evidence. The genealogical recordSonpi Bunmyaku (compiled 1377-1395) identifies Masakado as the third of Yoshimochi's eight sons, while the genealogy of theSōma clan (an offshoot of theChiba clan, who were descended from Masakado's uncleYoshifumi), theSōma Keizu (相馬系図), identifies him as the second of seven sons.[3] The latter text also claims that he was nicknamedSōma no Kojirō (相馬小次郎,Kojirō meaning "little second son") during his childhood, suggesting that he was raised in the district of Sōma (相馬郡) inShimōsa Province (part of modern southwestIbaraki Prefecture and northwest Chiba Prefecture),[14] though the factuality of this information has been disputed.[7] Masakado's mother is sometimes identified as the daughter of a certain Agata (no) Inukai no Harue (県犬養春枝), perhaps a local magnate from Sōma District.[7][15]
Masakado's year of birth is also unclear. Accounts of his exploits in the mid-930s suggest that his children were young enough to be still in the care of their mother, which may imply that he was born sometime around 900.[14] Later legend portrays Masakado as the reincarnation of scholar and politicianSugawara no Michizane (later deified as the godTenjin), who died in 903 (Engi 3).[16]
At some point in his late teens, Masakado went to the capital city ofHeian-kyō (Kyōto) and served in the household of theimperial regentFujiwara no Tadahira. He is said to have aspired for a position within the imperial police force, theKebiishi, but failed to obtain court rank or any significant office in spite of his credentials and his patron's high status.[14][9]
Disagreement exists about the exact cause of Masakado's rebellion. While some sources portray the uprising as revenge for his failure to secure a government post,[9][17] theShōmonki (将門記, also read asMasakadoki), an anonymousmonograph on Masakado's life believed to have been completed as early as the 940s,[18] suggests that the conflict originally began in 931 (Jōhei 1) as a dispute between Masakado, freshly returned from Heian-kyō, and his paternal uncleTaira no Yoshikane (平良兼) over a woman.[10] The identity of this woman is uncertain, though one theory suggests that it may have been a daughter of Yoshikane who married her cousin and apparently went to live with him against her father's wishes.[19][20][21][22] (Aristocratic marriages during the Heian period were usuallymatrilocal; the wife continued to reside with her parents while the husband either moved in with his wife's family or simply visited her.)[23] Besides this affront to his honor, Masakado not obtaining any post or rank in the capital might have been another factor in Yoshikane's opposition to the marriage.[19] Another theory based on folk tradition meanwhile suggests that Masakado and Yoshikane quarreled over a daughter ofMinamoto no Mamoru (源護), former senior secretary (大掾,daijō) ofHitachi Province who had married off his daughters to Masakado's uncles, Yoshikane among them.[19]
On the other hand, theKonjaku Monogatarishū (c. 1120) gives another reason for the conflict, namely that Masakado's uncles had appropriated thelands the young man was supposed to inherit from his late father. Masakado's uncleTaira no Kunika (平国香), who as Takamochi's eldest son was the head of the clan, might have tried to take over his younger brother Yoshimochi's property and place it under his control. Kunika, like Yoshikane, was related by marriage ties to Mamoru, who would eventually become involved in the conflict.[10][15][19]
In the 2nd month of 935 (Jōhei 5), Masakado and his men were ambushed by Mamoru's three sons,Tasuku, Takashi, and Shigeru, at a place called Nomoto (野本) in thedistrict of Makabe (真壁郡), near the border between Hitachi and Shimōsa (modernChikusei, Ibaraki), but managed to repel their attack; the three brothers all died in the battle. In retaliation, Masakado then burned and ransacked the houses of Tasuku's supporters across southwestern Hitachi. Kunika also died during this conflict, under circumstances not entirely clear: he may have either been killed during the skirmish at Nomoto or when Masakado set fire to his residence.[19][24]
On the 21st day of the 10th month of the same year,Taira no Yoshimasa (平良正), Masakado's paternal uncle or cousin who was also related by marriage to Mamoru, seeking to avenge the deaths of Kunika and Mamoru's sons, faced Masakado in battle in the village of Kawawa (川曲村) in western Hitachi (identified with the town ofYachiyo, Ibaraki)[22] but Masakado once again proved the victor; more than sixty of Yoshikane's men were killed while the rest dispersed.[22][25]
After his humiliating defeat, Yoshimasa called to Yoshikane – now the vice-governor of Kazusa Province – for aid, who then gathered a large number of warriors from Kazusa and Shimōsa such that officials from the two provinces initially attempted to prevent their dispatch (Such protests were later withdrawn after the issue was deemed to be a private matter beyond the sphere of state affairs). On the 26th day of the 6th month of 936 (Jōhei 6), Yoshikane led his massive army to Hitachi, where he joined forces with Yoshimasa and Kunika's sonSadamori (who had been in the capital when his father was killed and initially took a neutral stance), whom he had prevailed upon to take part in the attack against Masakado. They made contact at the border between Hitachi andShimotsuke (modernTochigi Prefecture) with Masakado, who went there to verify reports about a plan to launch a joint attack on him from the north. Despite only having about a hundred poorly-equipped soldiers with him, Masakado inflicted heavy casualties upon his enemies' several thousand strong army. Scattered and thrown into confusion, Yoshikane and the remnants of his forces fled to theprovincial headquarters of Shimotsuke, Masakado pursuing them. Although he managed to surround his uncle in the governmental offices, Masakado, seemingly concerned about subsequent censure should he kill Yoshikane then and there, allowed him to escape through a gap in his western line. He then filed a formal grievance with the provincial authorities in neighboring provinces before returning to his territory.[22][25][26]
Not long after his victory, Masakado received a summons from the imperial court because of a complaint lodged against him by Minamoto no Mamoru over the battle at Nomoto. Masakado then hurried to the capital to give an account of himself; his lord, Fujiwara no Tadahira, probably intervened in the case and helped lighten his punishment. He was eventually pardoned early the following year (937 / Jōhei 7) when a generalamnesty was declared at the occasion ofEmperor Suzaku's coming of age (genpuku).[25][26]
Anxious to avenge his defeat, Yoshikane almost immediately recommenced hostilities upon Masakado's return. He first launched an attack on Masakado at theKogai River near the border between Shimōsa and Hitachi while displaying portraits of Yoshimochi and Takamochi (Masakado's father and grandfather) in front of his vanguard. This ploy succeeded in weakening the morale of Masakado and his men, who "withdrew, carrying their shields." (Shōmonki) Afterwards, Yoshikane burned a critical stable and some houses at Masakado's base in Toyoda District (豊田郡) in Shimōsa to weaken his ability to make war. Masakado launched a counterattack some days later, but was again defeated due to being struck by a severe pain in his legs (thought to be due toberiberi). During his retreat, Masakado had his wife (Yoshikane's daughter) and children flee by boat for their safety, but Yoshikane discovered them and carried them off to Kazusa. The woman's brothers eventually allowed them to escape back to Masakado.
In 939 (Tengyō2, 12th month), Masakado led a minor rebellion which is also known asTengyō no Ran. The armed struggle began when Masakado led an attack on an outpost of the central government inHitachi Province, capturing the governor. In December of that year, he conqueredShimotsuke andKōzuke Provinces; and he claimed the title of Shinnō (NewEmperor).
The central government inKyoto responded by putting abounty on his head, and fifty-nine days later his cousinTaira no Sadamori, whose father Masakado had attacked and killed, andFujiwara no Hidesato, killed him at the Battle of Kojima (Shimōsa Province) in 940 and took his head to the capital.
The head found its way to Shibasaki, a small fishing village on the edge of the Pacific ocean and the future site ofEdo, which later becameTokyo. It was buried. Thekubizuka, or grave, which is located in the present dayŌtemachi section of Tokyo, was on a hill rising out ofTokyo Bay at the time. Through land reclamation over the centuries, the bay has receded some three kilometers to the south.
When Masakado was preparing for his revolt, a vast swarm of butterflies appeared in Kyoto, a portent of the upcoming battle.[27]
Over the centuries, Masakado became ademigod to the locals who were impressed by his stand against the central government, while at the same time feeling the need to appease hisonryō (vengeful spirit). The fortunes of Edo and Tokyo seemed to wax and wane correspondingly with the respect paid to the shrine built to him at thekubizuka (ja); neglect would be followed by natural disasters and other misfortunes. Hence, to this day, the shrine is well maintained, occupying some of the most expensive land in the world in Tokyo’s financial district facing the Imperial Palace. His tomb (which contains only a monument to his head) is near exit C5 of Tokyo'sŌtemachi subway station.
Other shrines which he isdeity of includeKanda Shrine (神田明神,Kanda-myōjin) (located inKanda), andTsukudo Jinja (which has multiple locations.)
InGifu Prefecture, there is a Mikubi shrine (ja) dedicated to Taira no Masakado. According to a legend left at theShinto shrine, a priest at a shrine inMino Province prayed to akami (Shinto deity) to prevent the head of Taira no Masakado, who was beheaded in Kyoto, from returning toKantō for revenge, and the kami shot the head off with ayumi (bow) as Taira no Masakado flew back to Kantō. The Mikubi Shrine was built on the spot where the head fell.[28]
