This beautiful frog is a master of camouflage.  I often find it resting on tree branches, blending in with the surrounding green leaves.

On Kume Island the tree frogs transform to a golden brown when mating.

They construct a foam nest on a tree branch above a still water source. Eventually the foam liquefies when the eggs are ready to hatch.

Not all frogs survive to make the nest. The Akamata is the most common snake on the Okinawan Islands.  It feeds on venomous habu snakes, baby sea turtles, lizards and frogs.
