The Asiatic salamanders are primitive salamanders found all over Asia, and in European Russia. They are closely related to the giant salamanders, with which they form the suborder Cryptobranchoidea. About half of hynobiids currently described are endemic to Japan.
Hynobius yangi, the Kori salamander, is a species of salamander endemic to southeastern South Korea. It is a lentic-breeding species similar to the Korean salamander but is distinguished by factors including tail shape and dorsal coloration. The species is known from the vicinity of the type locality in Gijang County in northeastern Busan and from the nearby Ulju County in western Ulsan.
Hynobius quelpaertensis, the Jeju salamander, also spelled Cheju salamander, is a species of salamander found on various islands and peninsulas off the southwestern coast of the Korean Peninsula, including Jindo, Geojedo, Jejudo, and Namhae. It inhabits moist mountain forests.
The Abe's salamander is a species of salamander in the family Hynobiidae. It is endemic to Japan and known from southwestern Honshu in northern parts of the Fukui, Kyoto, and Hyōgo Prefectures. The specific name abei honours professor Yoshio Abe, a Japanese zoologist.
Hynobius is a genus of salamander in the family Hynobiidae, occurring in Japan, Korea, China, Taiwan and Far East Russia.
The Oita salamander is a species of salamander in the family Hynobiidae endemic to Japan. Named after Ōita Prefecture, its natural habitats are temperate forests, rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, and irrigated land in western Japan. It is threatened by habitat loss, due to the increasing construction of homes within its habitat. The Oita salamander is considered to be vulnerable by the (IUCN) Red List of Threatened Species with a declining population.
The Hakuba salamander or Japanese mountain salamander is a species of salamander in the family Hynobiidae. This salamander is also synonymous with the mountain salamander. It is endemic to Japan. Its natural habitats are temperate forests, rivers, swamps, freshwater springs, and plantations. It is threatened by habitat loss.
Hynobius naevius, also known as the spotted salamander, Sagami salamander, Japanese salamander, and blotched salamander, is a species of salamander in the family Hynobiidae. It is endemic to northwestern Kyushu, Japan. Earlier records from Honshu represent other species.
The Ezo salamander, also known as the Hokkaido salamander, Noboribetsu salamander, or Ezo Sanshouo in Japanese is a species of salamander in the family Hynobiidae. Prior to 1923 the species was also classified by the binomial scientific name Satobius retardatus. H. retardatus is endemic to Japan's northernmost prefecture, the island of Hokkaido. The species is a pond-type salamander, and its natural habitats are temperate forests, temperate shrubland, swamps, freshwater marshes, intermittent freshwater marshes, freshwater springs, irrigated land, canals, and ditches.
The amber salamander, amber-colored salamander, tortoiseshell salamander, or Stejneger's oriental salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests and rivers. It is threatened by habitat loss.
The Tokyo salamander is a species of salamander in the family Hynobiidae, endemic to Japan. Its natural habitats are temperate forests, freshwater springs, arable land, irrigated land, and canals and ditches. It is threatened by habitat loss. Many different species of amphibian have unbalanced sex ratios. This trend is no different in Hynobius Tokyoensis; the sex ratio between males and females is about 1.5:1. Although this does not play as large of a role as habitat destruction when it comes to the decline of this species, it is still significant. Considering their environmental preferences, they are usually found in paddy fields. Mid-Summer drainage from these fields hinders the population's ability to thrive as this would occur before these populations could complete metamorphosis.
The Amami tip-nosed frog is a species of frog in the family Ranidae. It is endemic to the Amami Islands, a part of the Ryukyu Islands, Japan. Specifically, it is known from the islands of Amamioshima and Tokunoshima.
The Japanese brown frog is a species of frog in the family Ranidae, endemic to Japan. Its natural habitats are temperate grassland, rivers, swamps, irrigated land, and seasonally flooded agricultural land.
Odorrana supranarina is a species of frog in the family Ranidae. It is endemic to Ryukyu Archipelago, Japan, and is known from the islands of Ishigaki and Iriomote, both in the Yaeyama Group. The specific name supranarina refers to the large size of this species —at the time of the species description, it was the largest member of the so-called Rana narina complex. Common name greater tip-nosed frog has been coined for it.
Odorrana utsunomiyaorum is a species of frog in the family Ranidae. It is endemic to Ryukyu Archipelago, Japan, and is known from the islands of Ishigaki and Iriomote, both in the Yaeyama Group. The specific name utsunomiyaorum honours Taeko and Yasuaki Utsunomiya for their contributions to clarifying the amphibian fauna of the Yaeyama Group.
Hynobius shinichisatoi, the Sobo salamander, has only been found in streams in the Sobo, Katamuki and Okue Biosphere Reserve, Japan. It is black in colour.
Hynobius fossigenus is a species of salamander in the family Hynobiidae, and is found in some prefectures in Kantō and Chūbu districts in Japan.
