Later, due to Taiho Ritsuryo (Taiho Code) edited in 701, Kori/Ryo was abolished, and Gun (administrative district) was implemented and was administrated by Shitokan (four classifications of bureaucrats' ranks) as Gunji: Dairyo (first-ranked Gunji), Shoryo (second-ranked Gunji), Shusei (third-ranked Gunji) and Shucho (fourth-ranked Gunji in charge of drafting and accepting documents).
やがて、701年（大宝(日本)元年）に編纂された大宝律令により、評が廃止されて郡が置かれ、郡司として大領・少領・主政・主帳の四等官に整備される。
