Year Published:	2004
Assessor/s:	Yoshio Kaneko, Masafumi Matsui
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Contributor/s:
Justification: Listed as Endangered, because its Extent of Occurrence is less than 800 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its habitat. Extent of occurrence less than 800 km2. Fragmented. Continuing decline.

Geographic Range [top]

Range Description:	This species is distributed on six Japanese islands: Amamioshima, Tokuonoshima, Yorojima, Okinawajima, Sesokojima and Tokasikijima. There are old records (three museum specimens) from Mount Kuanyinshan, just north of Taipei, in Taiwan, Province of China (Zhao and Adler 1993), where the species is presumed to be extinct (Zhao 1998).

Population [top]

Population:	This is an uncommon species, and it is difficult to observe outside the breeding season. It is considered to be rare on Okinawa (Hayashi et al. 1992).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This species occurs in broad-leaved evergreen forest, secondary forest, grassland and swamps. It inhabits vegetated areas with constantly humid substrates, and breeds in shaded still waters such as ponds and temporary pools in forests. On Tokunoshima the species occurs in and near sugar cane fields, at altitudes of 100-200m asl (Utsonomiya, Utsonomiya and Kawachi 1978). It is terrestrial, and while eggs are laid on land in one or several clutches, the larvae develop in water.
Systems:	Terrestrial; Freshwater
