仁德天皇
According to "Nihon Shoki", the Hata clan (descendants of Qin Shi Huang) arrived in Yamato in 403 (the fourteenth year of Ōjin) as the vanguard of 120 provinces. According to the "Shinsen Shōjiroku", the Hata clan were dispersed throughout a number of provinces during the reign of Emperor Nintoku and forced to practice sericulture and silk manufacturing for the court. When the finance ministry was set up in the Yamato court, Hata no Otsuchichi became chief of several departments (伴造; "") and was appointed Ministry of the Treasury (大蔵省; "Okura no jo"); the heads of the family were apparently financial officials of the court.
