The Asiatic toad or Chusan Island toad (Bufo gargarizans) is a species of toad endemic to East Asia. The species was previously classified as Bufo bufo gargarizans, a subspecies of the common toad. 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.
The Asiatic toad avoids dense forests, but is found in most other habitats, including grasslands, open forests, meadows, and cultivated areas. It prefers humid areas, and is rarely found at altitudes of more than 800 meters.

Likely
About 40% of wildlife watchers report an Asiatic Toad sighting in Nanjing on a given day, based on 126 verified sightings from GBIF citizen-science data. It is the most-seen of the 11 amphibians we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
July and September
In those months about 60% of wildlife watchers report an Asiatic Toad in Nanjing on a given day, against under 5% in December and January, the lowest months. Those are among Nanjing's wettest months, with about 170 mm of rain a month against 40 mm in December.
6th of 21
Of the 21 cities where we can rate Asiatic Toad sightings, Nanjing ranks 6th at about 40%. The best odds are in Tianjin (China, about 50%), Guiyang (China, about 50%) and Hefei (China, about 50%).
Same order: Anura
The closest relatives of the Asiatic Toad that you can see in Nanjing (order Anura, Frogs and Toads) are Ornate Chorus Frog (about 30%), Zhenhai Brown Frog (about 20%) and Boreal Digging Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Asiatic Toad is recorded against all the amphibians logged in Nanjing (126 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
