At this time, male frogs migrate to still water areas such as low altitude rice paddies and wetlands to chirp loudly, laying about 250-800 eggs at a time. During the non breeding season, it often calls before rain and is a true rain frog.

The Japanese wrinkled frog is a true frog native to Japan, introduced to Hawaii in the late 19th century. It is sometimes considered a single species, similar to the Imienpo station frog found on the East Asian continent. The difference between these two species and others lies in their rough and uneven skin. It lives and reproduces in various freshwater environments, including ponds, streams, and wetlands. The International Union for Conservation of Nature does not consider this species to face any significant threats.

The Tianzi frog, scientific name Rana tagoi, is a species of frog in the family Ranidae of the order Anura in the class Amphibia. It lives in forests ranging from low mountains to altitudes below 2000 meters. The diet is animal food, including insects, spiders, land snails, etc. Before metamorphosis, young children consume the yolk in their bodies to sustain their lives. The basal subspecies lays 60-110 eggs from January to February or April to May, the subspecies キタゴガエ from February to March, and the subspecies クシマタゴガエ from October to April in areas such as puddles near streams or streams.

The tree frog is a species of amphibian belonging to the Rhacophoridae family. This kind of frog breeds in a special way. They make foam nests underground. They will crawl on the edges of rice paddies and swamps, and dig caves above the water surface. The female carries the smaller male on her back, and both are buried in a hole that is 6-9 centimeters wide and 10-15 centimeters above the water surface. The interior of this nest is smoothed out through female movement, and then at night, it is filled with white material filled with air bubbles.
