The basionym for the species is Ilex japonica Thunb.; the corresponding plant description by the Swedish naturalist Carl Peter Thunberg was published in 1784. The accepted first description under the name Mahonia japonica by Augustin de Candolle Pyrame was published in 1821. The genus affiliation is seen, however, controversial; According to the 1818 GRIN published description of Robert Brown under the name Berberis japonica ( Thunb. ) R. Br is valid.
