The Black kokanee or Kunimasu, once thought to be extinct, is now classed as extinct in the wild. This list of freshwater fish recorded in Japan is primarily based on the IUCN Red List, which, for fish found in inland waters, details the conservation status of some two hundred and sixty-one species, seventy-three of them endemic. [1]
The Kunimasu species was originally endemic to a single location, Lake Tazawa in Akita Prefecture, Japan. [2] In 1935, eyed eggs (a fertilized stage of eggs) of this fish species were introduced into several other lakes in Japan, including Lake Saiko, Yamanashi Prefecture, in an attempt at translocation that was thought to have been unsuccessful.

As of September 2016, the International Union for Conservation of Nature (IUCN) lists 65 extinct fish species, 87 possibly extinct fish species, and six extinct in the wild fish species. [ 1 ] [ 2 ] Cartilaginous fish
Now that they are recognized as important, fishermen trade them to scientists or other officials. Before the 1980s, this was a problem for coelacanth populations. In the 1980s, international aid gave fiberglass boats to the local fishermen, which moved fishing beyond the coelacanth territories into more productive waters.

Hokkaido wolf (Canis lupus hattai), one of 110 [1] taxa classed as Extinct [2] on the 2020 Japanese Red List (Hokkaido University Museum). The Japanese Red List (レッドリスト, reddo risuto) is the Japanese domestic counterpart to the IUCN Red List of Threatened Species.
Takifugu chinensis, the Chinese puffer, is a species of fish in the family Tetraodontidae (pufferfish) that is found in coastal waters of China, Japan and Korea. [1] This critically endangered pufferfish has drastically declined because of overfishing and habitat loss, but it is possibly also threatened by the widespread release/escape of aquacultured Takifugu rubripes within its range.
