In the twelfth century, in place of the previous Kanmotsu rippo, public taxes called Ikkoku heikinyaku (taxes and labor uniformly imposed on shoen manors and provincial lands) and Gokeninnyaku (odd-jobs for vassals) were collected from not only Kokuga owned public fields but also Shoen, and the tithes from these taxes were also called Kanmotsu and this term was used until the period of the Northern and Southern Courts (Japan).
12世紀に入ると既存の官物率法に代わって、国衙領の公田のみならず、荘園の年貢に対しても一国平均役・御家人役などの形で公租が賦課されるようになり、これらの賦課による貢納物に対しても官物という言葉が用いられるようになり、南北朝時代(日本)の頃までこの呼称が用いられた。
