The present invention provides a kidney production method including a step of tissue-specifically removing a metanephric mesenchyme of a metanephros of a non-human animal； a step of transplanting, into the metanephros, a kidney precursor cell derived from a non-human animal which is allogeneic or xenogeneic to the non-human animal； and a step of advancing development of the metanephros, which is a step in which the transplanted kidney precursor cell is differentiated and matured to form a part of the kidney.
