Although Hideyoshi had not had the title of Taiko (the father of the Imperial adviser) until he handed over the title of Kanpaku (the chief adviser for an emperor) to Hidetsugu TOYOTOMI in 1591, all his land surveys including the surveys conducted before 1591 were included in the 'Taiko-kenchi,' because Hideyoshi had been pleased with the use of the title of 'Taiko' since 1591.
1591年に関白を豊臣秀次に譲るまでは太閤（たいこう）ではなかったが、1591年以降は秀吉自身が「太閤」の称号を好んで使用したこともあり、1591年以前の検地も含めて「太閤検地」と言う。
