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 general amnesty was declared at the occasion of Emperor Suzaku's coming of age (genpuku). Masakado and Yoshikane (937-938) Anxious to avenge his defeat, Yoshikane almost immediately recommenced hostilities upon Masakado's return. He first launched an attack on Masakado at the Kogai 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 to beriberi). 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. Death In 939 (Tengyō 2, 12th month), Masakado led a minor rebellion which is also known as Tengyō no Ran. The armed struggle began when Masakado led an attack on an outpost of the central government in Hitachi Province, capturing the governor. In December of that year, he conquered Shimotsuke and Kōzuke Provinces; and he claimed the title of Shinnō (New Emperor). The central government in Kyoto responded by putting a bounty on his head, and fifty-nine days later his cousin Taira no Sadamori, whose father Masakado had attacked and killed, and Fujiwara no Hidesato, killed him at the Battle of Kojima (Shimōsa Province) in 940 and took his head to the capital. Aftermath The head found its way to Shibasaki, a small fishing village on the edge of the ocean and the future site of Edo, which later became Tokyo. It was buried. The kubizuka, or grave, which is located in the present day Ōtemachi section of Tokyo, was on a hill rising out of Tokyo Bay at the time. Through land reclamation over the centuries, the bay has receded some three kilometers to the south. Deification When Masakado was preparing for his revolt, a vast swarm
