The forest green tree frog or Kinugasa flying frog (Zhangixalus arboreus) is a frog. It lives in Japan on Honshu Island. People have seen it as high as 2000 meters above sea level.
The adult male frog is about 42-60 mm long from nose to rear end and the adult female frog is about 59-82 mm long. They have more webbed skin on their front feet than on their back feet. The skin of the frog's back is bright green. It can have spots. The skin of the frog's belly is white with brown spots. The iris of the eye is red-brown in color.
This frog lives in trees and on the ground near dead leaves. When it is time to aly eggs, the female frog makes a nest out of foam and then puts hundreds of eggs in the nest. The male frog fertilizes the eggs. Then the foam becomes hard.
Human beings visiting the part of Honshu where the frog lives come to its ponds to watch it. They do this for fun.
