The old theories about the setup of 'Ise Yamada bugyo' by the Edo bakufu, such as it having been established at the request of the members of Yoda sanpo, or that a Goshuinjo (letter of command with a stamp to show its authenticity) from Hideyoshi TOYOTOMI to Jobu Ecchunokami (Governor of upper-Ecchu Province), was the precedent for Yamada bugyo in the Edo bakufu, are still compatible with the idea of Tadasuke OOKA as Yamada bugyo.
徳川幕府の「伊勢山田奉行」の設置について「山田三方会合衆の要請に依った」とか昭和四年刊行の宇治山田市史の「豊臣秀吉の上部越中守への御朱印状を以て江戸幕府・山田奉行の前例とする」説は、現在に於いても大岡忠相の山田奉行手柄話と共にまことしやかに語られている。
