The
Asiatic toad or
Chusan Island toad (
Bufo gargarizans) is a species of
toad endemic to
East Asia. It is common in China (specifically
Anhui,
Fujian,
Gansu,
Guizhou,
Hebei,
Heilongjiang,
Henan,
Hubei,
Hunan,
Inner Mongolia,
Jiangsu,
Jiangxi,
Jilin,
Qinghai,
Shaanxi,
Shandong,
Shanxi,
Sichuan, and
Zhejiang) and portions of the
Russian Far East (up north to the
Amur River valley and on
Sakhalin Island, and east to
Transbaikalia in
Siberia), but relatively rare on the
Korean Peninsula. Asiatic toads are also found on the
Miyako Islands of southern Japan, although they have been extirpated from some islands in recent years, possibly including
Okinawa. The Miyako
subspecies,
Bufo gargarizans miyakonis, is also known as the Miyako toad.
