B. torrenticola has a body that is robust and a canthus that is sharp and slightly concave. The snout to eye distance is longer in females than in males, and the interorbital is only slightly concave.The tympanum is indistinct. The limbs are long, especially distally, and the tips of the fingers and toes are blunt. The webbing is not well developed. The males have a middle subarticular tubercle on the 4th toe. Inner and outer metatarsal tubercles are oval. The tibio-tarsal articulation reaches the middle of the parotoid gland, and the skin on the back of these toads are covered with warts except around the head. However, the skin is nearly smooth in breeding males. There is a row of warts dorsolaterally behind the parotoid gland. The parotoid gland is short. The mean snout to vent length for males is 95 mm (range 70-121)and for females, 121 mm (range 88-168). There is no vocal sac or vocal opening. The nuptial pads in males are black on the first three fingers.

The type locality is Odaigahara, Nara Pref. B. torrenticola is sometimes regarded as a subspecies of B. japonicus because the artifical hybrids have been found to be fertile. But, isolation seems complete in the zone of sympatry.

Diploid chromosome (2n), with 6 large pairs and 5 small ones, making 22 chromosomes in total.
