"Sweet Impact" is an upbeat dance tune just right for bright and sunny spring days. It's the song BoA belted at her Yokohama concert last month while wearing an eye-catching hat by Ed Hardy, the famous fashion designer.

The track has found a big audience in Japan where it's being used to help promote the cosmetics brand CF.

The song is available in two forms, CD and DVD. The DVD includes the music video to the song, featuring BoA in a splendid dance performance in a stylish fedora.

The track "Bad Drive," which highlights BoA's singing power, is also included with the single.

BoA last week wrapped up a successful four-city tour of Japan. Starting with this single, she plans to devote more time to working in Korea.
