Lullatone is a popular music group based in Nagoya, Japan, whose music is characterized by an innocent, child-like quality and spare, lo-fi sounds. Although the group refers to their style of music as "pajama-pop", it is commonly included in such musical subgenres as Twee pop, Indie pop and Electronica. It draws influence from such diverse sources as Bossa Nova, French pop music of the 1960s, children's songs and Musique concrète.
Lullatone's founder was Shawn James Seymour, a native of Louisville, Kentucky. Its other principal member is Japanese native Yoshimi Tomida (Tomida Yoshimi, in traditional Japanese name order). Seymour began musical experimentation during his high school years in the late-1990s, using keyboards and cassette tape recorders.
