Removed from the synonymy of Microhyla ornata by Dubois, 1987, Alytes, 6: 4, where it had been placed by Okada, 1931, Tailless Batr. Japan. Empire: 71, and Inger, 1947, Fieldiana, Zool., 32: 324. Matsui, Ito, Shimada, Ota, Saidapur, Khonsue, Tanaka-Ueno, and Wu, 2005, Zool. Sci., Tokyo, 22: 489-495, confirmed through analysis of mtDNA sequences the distinctiveness of this taxon from Microhyla ornata and Microhyla fissipes (its sister species). Goris and Maeda, 2004, Guide Amph. Rept. Japan: 127-129, provided an account, as Microhyla ornata, for Japan, map, and photograph. Maeda and Matsui, 1990, Frogs Toads Japan, Ed. 2: 174-177, provided an account (as Microhyla ornata) for Japan. Kuramoto and Joshy, 2006, Curr. Herpetol., Kyoto, 25: 15-27, compared the morphology and calls of this species with Microhyla ornata and Microhyla okinavensis.  In the Microhyla fissipes species group of Garg, Suyesh, Das, Jiang, Wijayathilaka, Amarasinghe, Alhadi, Vineeth, Aravind, Senevirathne, Meegaskumbura, and Biju, 2018 "2019", Vert. Zool., Senckenberg, 69: 1–71.
