Kousuke Atari is a J-Pop artist, born July 13, 1980, on Nihon Amami island. He is signed onto Sony Music Japan's Epic Records Japan division. His single Tane wo Maku Hibi (The Days When Seeds are Scattered) was used as the thirteenth ending theme song to the anime Bleach.

When Kousuke was in high school, he became a fan of Hajime Chitose. Inspired, he began to teach himself how to sing in shima-uta style.

In 2000, he won the Amami Folk Song Grand Prix's 'New Member Award'. He also won the Japanese Folk Song Association Award. He continued to participate in numerous Ryukyu based folk festivals and tournaments.

He began releasing very traditional albums in 1999, under the Jabara Records - label. He released two straight traditional albums, Atari and Kurudando, followed by the mini album Shodon, which saw him experimenting with a wider range of instruments and musicians, and finally the full-length Notus, which saw an even further departure from the traditional style with jazz elements and other influences. After these four releases he moved to a more modern pop style with his Day! Records release, Materia.

In September of 2005, he gained much attention with the release of an indie mini album entitled Materia. Materia is the first of his musical releases to have an undeniable 'pop' music feel to it, although it managed to retain the flair and beauty of his traditional style vocals. The album shot to #5 on the indie music charts, and sold over 7000 copies.
