In the Section Rana, subgenus Rana, Rana tagoi group of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 333. Most closely related to Rana tagoi, according to the original publication. Tanaka, Matsui, and Takenaka, 1994, Zool. Sci., Tokyo, 11: 753–757, discussed the relationships of this species with Rana ornativentris, Rana pirica, Rana tagoi, and Rana japonica. See comment under Rana tagoi. Maeda and Matsui, 1990, Frogs Toads Japan, Ed. 2: 68–71, provided an account. Goris and Maeda, 2004, Guide Amph. Rept. Japan: 94-96, provided an account, map, and photograph. Eto and Matsui, 2014, Mol. Phylogenet. Evol., 79: 231–239, reported on molecular phylogenetics and noted substantial mtDNA introgression with populations of its sister species, Rana tagoi, which had confounded previous attempts at recovering phylogeny based only on mtDNA trees. They also noted that Rana tagoi is composed of multiple lineages forming a paraphyletic series with respect to Rana sakuraii. Tokita, Iizuka, and Eto, 2023, Herpetol. Notes, 16: 761–771, compared Rana sakuraii and Rana tagoi morphmetrically.
