Habitat:
This species inhabits plains and hillsides. It breeds from January to April in still waters in rice fields, ponds, ditches, and pools. It is often sympatric with Rana uenoi, but different calls seem to prevent hybridization. Eggs are laid in a globular mass containing 400-500 eggs, dark brown in animal hemisphere and with diameter 1.7-2.3 mm. Matured larva are over 34 mm in total length, with a dark spot on each side of the back (Matsui and Maeda 2018).
Range:
This species is found only on Tsushima Island in the Korea Strait, in Japan. This island is administered by Nagasaki Prefecture. It occurs above 20 m asl. The extent of occurrence (EOO) of its mapped distribution is 1,015 km2.
