CHEMISTRY is a Japanese J-R&B/J-Urban duo who debuted in 2003 under the DefSTAR RECORDS label.
CHEMISTRY is one of Japan's top pop duos. Kawabata Kaname and Dochin Yoshikuni beat out over 19,000 applicants who competed in the ASAYAN "Chou Danshi Vocalist Audition," which was held from October 1999 to January 2001. The finalists of the auditions were paired up in different combinations and released limited-copy singles, but it was Kawabata and Dochin's "Saigo no Yoru" in December 2000 which sold all 35,000 copies and landed 9th on the Oricon charts. They were announced as the winners in January 2001 and made their official debut as CHEMISTRY with their single, "PIECES OF A DREAM," which landed #1 on the Oricon charts and went on to become one of the year's top singles, selling over a million copies. Kiyoshi "KC" Mitsuo, CHEMISTRY's producer, left from the group after they released their remix album Between the Lines.
