About
Dryophytes japonicus, with frequently used synonym Hyla japonica, commonly known as the Japanese tree frog, is a species of anuran native to Japan, China, and Korea. It is unique in its ability to withstand extreme cold, with some individuals showing cold resistance at temperatures as low as −30 °C for up to 120 days. Japanese tree frogs are not currently facing any notable risk of extinction and are classified by the IUCN as a species of "least concern". Notably, it have been sent to space in a study that explored the effect of microgravity on Japanese tree frogs. Some consider that Dryophytes japonicus is synonymous with Hyla japonica. However, a 2025 study treated that this species as Dryophytes japonicus again, and separated northern species as Dryophytes leopardus.
