"Kaeru no Uta" (蛙の歌, "Frog's Song") is a traditional Japanese children's song and nursery rhyme. It is one of the most well-known songs for young children in Japan, often one of the first songs they learn. The lyrics are onomatopoeic, imitating the sound of a frog ("gero gero gero gero"), and describe a frog and its activities. Its simple melody and catchy rhythm have made it a cultural staple for generations.
