Hyla japonica, commonly known as the Japanese tree frog, is a small amphibian native to Japan and parts of East Asia. It typically measures about 3 to 5 centimeters in length and is characterized by its bright green color, which helps it blend into its natural surroundings. This species is often found in rice paddies, gardens, and forests, where it thrives in humid environments. The Japanese tree frog is known for its distinctive croaking sound, especially during the breeding season. It primarily feeds on insects and plays a vital role in controlling pest populations. Hyla japonica is also an important indicator of environmental health, as its presence reflects the quality of its habitat.
