Style.
Matsutoya's arrangements often involve classical string and woodwind instruments. He was one of the first composers to use these instruments in j-pop arrangements. His style is most distinct in his usage of the flute and harp. He also frequently uses choruses in arrangements, and many artists have made their debuts in the back-chorus of Yumi Matsutoya's songs.
Several Japanese arrangers show influence from Matsutoya in their arrangements.
