Kousuke Atari(中 孝介,Atari Kōsuke?, born July 13, 1980, on Amami Ōshima, Japan) is a Japanese enka artist. He is a self-trained musician, and performs in the difficult shimauta (island-song) style of his hometown. While his style of music is close to mainstream pop, his vocals have an undoubtedly traditional Japanese flavor, and his inspiration still comes from his traditional roots.
The song "Natsu Yuuzora (夏夕空; Summer Evening Sky)" was used as the ending theme in the Japanese anime adaptation of the manga series Natsume Yuujinchou. He also performed the song, "Kimi no Kakera (君ノカケラ; Pieces of You)", which was used in the third season.
The single "Tane wo Maku Hibi (種をまく日々; The Days When Seeds are Scattered)" was used as the thirteenth ending theme in the anime series Bleach.
