Haishakukin means the loan without interest which, as a financial aid, Edo-bakufu lent to Daimyos _??__??_, Hatamotos _??__??_, Jinjas _??__??_ temples and peasants. In this article, the author examine especially the Haishakukin lent to Daimyos, in order to investigate a relation between the Bakufu and the Hans.
Every Daimyo, without regard to his status to Shogun _??__??_, was equally qualified for Haishakukin. The amount of Haishakukin was different according to the largeness of his fief and his office in the Bakufu. The term of Haishakukin was ordinarily for ten years.
It was not the obligation but the favor for the Bakufu to lend Haishakukin. In order to get Haishakukin, Daimyos had to send in written applications to the Bakufu, explaining their financial difficulties and begging a favor. The applications were examined and decided by Kanjobugyos _??__??__??__??_, Rojus _??__??_ and Shogun. On examining and deciding them, they customarily adhered to precedents. In other words, if there was a precedent, the Bakufu almost always granted an application. But if there was no precedent, the Bakufu either granted or refused it at its discretion, although it was the rule for the Bakufu to refuse it. Therefore we may say that the Bakufu dealt with the applications at will through both precedents and discretions.
By these seemingly free and unrestricted means, the Bakufu carried through its definite policy for financial aid. The main purpose of Haishakukin was to ensure the due performance of offices of the Daimyos who were the officers of the Bakufu, and to favor the Tsuzukigara-Daimyos_??__??__??__??_—the Daimyos who were related to the Shogun's family. The Bakufu also lent Haishakukin to the common Daimyos, as a financial aid for the relief of disaster, the performance of Tenpu _??__??_ and the discharge of Goyo _??__??_. Thus, it is the concluding remark of this article that it was the aim of Haishakukin for the Bakufu to maintain the regime of governing union of feudal lords, the top of which was Shogun, through a financial support to Daimyos with its mighty power and great financial ability.
