Erroneously synonymized by some authors (e.g. POWO) with the Crimean ''F. × taurica,'' from which it differs morphologically and genetically.

|''Fagus okamotoi'' {{Small|Shen}}
|''F. crenata'' × ''F. japonica'' ?
|Unique phenotype, described from an area in which ''F. crenata'' and ''F. japonica'' are sympatric. So far, there is no genetic evidence for ongoing gene flow between the two Japanese species, which belong to different subgeneric lineages.
