Tsubasa Suzuki creates "asobi-uta" (play songs) that children, guardians, and childcare workers can enjoy together, drawing on his hands-on experience as a former nursery teacher. His signature song "Kaminari-don ga Yattekita" reached about 20 million YouTube views in two years, and "Daijobu Zukko" about 19 million views - songs hugely popular with young children of the Reiwa era. This time, it is a best-of album containing songs not available on CD or streaming, such as other play songs and interactive pieces that are repeatedly played and loved in everyday childcare and parenting scenes. It also includes an audio version of a read-aloud of the picture book "Yomu dake de Voice Percussion ni Naru Ehon: Kuttsuku Pantsu" (written by Tsubasa Suzuki / illustrated by Negosix), to be released by Asahi Shimbun Publications in July.
