Comment

Formerly confused with Hynobius akiensis according to the original publication, where morphometric and mtDNA markers were detailed. Raffaëlli, 2022, Salamanders & Newts of the World: 121, provided an account, summarizing systematics, life history, population status, and distribution (including a polygon map). Tomimori, Matsui, Okawa, Nishikawa, Tanabe, and Kamasaka, 2023, Zootaxa, 5293: 145–160, provided a molecular and morphological reassessment of the species delimitation as well as an expanded description and species account.
