This species inhabits forested plains and hillsides, but is usually abundant in montane regions up to 1,900 m asl. Occasionally it is found with R. japonica at lower altitudes. It breeds over a short period during January and late June in still waters in rice fields, marshes, and small pools. Eggs are laid in a large depressed globular mass with 1,000-1,900 eggs, 1.5-2.4 mm in diameter and dark brown in animal hemisphere. Matured larva are 43-60 mm in total length, without a dark spot on each side of their back. Metamorphosis takes place between June and August with SVL of 11-20 mm. It feeds on various insects, snails, slugs, and earthworms, and hibernates in soil on land or at the bottom of water in ditches and rice fields (Matsui and Maeda 2018).
