Kimeru (most often written either in Romaji (Kimeru) or with Katakana (キメル), but has been written as きめる (Hiragana) and (決める) (Kanji), (June 17, 1980) is a Japanese pop musician, singer, and stage actor. He is most famous for his work with The Prince of Tennis. He adopted the stage name Kimeru, which means "to decide" in Japanese, before debuting. Kimeru's birth name has never been announced publicly.

Born June 17, 1980 in Kumamoto-ken in Japan, after graduating from high school, he originally became a mailman, but later decided to pursue a career as a singer.

On December 5, 2001 Kimeru released his first single, "You Got Game?" with Absolute Productions/Birdie House Inc. The song was used as the first ending song for the anime テニスの王子様　(The Prince of Tennis, commonly called "TeniPuri" or "AniPuri"), which was based on a manga by the same name created by Takeshi Konomi. He followed up this release one year later with "Make You Free", which was also used as an opening song for later episodes of TeniPuri.
