Member of Jpop idol group, Morning Musume. Entered Morning Musume through the 'Morning Musume Love Audition 2002' as their 6th generation (along with Kamei Eri, Michishige Sayumi and then Hello! Project soloist, Fujimoto Miki). 6th gen debuted with Shabondama (MM 19th single), with Reina taking lead. The single sold over 150,000 copies.
Reina had also tried her luck with the 'Morning Musume Love Audition 21', but did not make it (glad she decided not to give up).
Do not mix up Tanaka Reina with Japanese actress, Tanaka Rena.
Till this day, she still looks like a 12 year old.
