Nagayo Motoori (本居長世) (1885-1945) was a Japanese composer known for children’s songs. Although his grandfather and guardian protested, he pursued a music degree at Tokyo School of Music (present day Tokyo University of the Arts) and began working there as a research assistant studying traditional Japanese music. He was well-known for his talent on the piano (for which he served as an assistant professor) but switched suddenly to composing due to a finger injury. During his employment at the university, he taught other important Japanese musicians such as Shinpei Nakayama.
Children’s music gained popularity in Japan mainly due to the children’s magazine Akai Tori (赤い鳥). Motoori had his first children’s song published in a similar magazine, Kin no Fune (金の船) and began gaining significant recognition thanks to a performance of his songs by his daughter Midoriko, who went on to become the number one singer of children’s music. Eventually, Motoori traveled all over Japan and abroad, performing his music with his three daughters.
