The Japanese tree frog, a representative of the Manchurian fauna, is characterized by an outstanding cold resistance among the anuran amphibian species studied so far. Almost 70% of the specimens from the population inhabiting the middle Amur River withstand the cooling down to-30°C; some animals, down to-35°C. This exceeds more than twofold the cold hardiness of the wood frog (Lithobates sylvaticus LeConte, 1825), which has been considered earlier to be the most cold-resistant species. The ability of H. japonica to survive for four months in the frozen state at low temperatures makes this species independent of the temperature overwintering conditions.
日本树蛙是满洲动物区系的代表物种，在迄今研究的无尾两栖动物物种中，它具有出色的抗寒能力。居住在黑龙江中游的种群中，近70%的标本能承受降温至-30°C；一些个体甚至能承受降温至-35°C。这比之前被认为是最耐寒物种的林蛙（Lithobates sylvaticus LeConte，1825）耐寒能力高出两倍多。日本树蛙在低温冰冻状态下存活四个月的能力，使得该物种不受越冬温度条件的限制。
