Born in Fukuoka Prefecture, Tamura gained notoriety as an advocate for the Lolita fashion movement, wearing Lolita-style clothing in public, as well as for her music releases, often in music videos and on the covers of her CD releases. Affectionately called Yukarin by her fans, several of her releases have been used as opening and ending themes for anime series, while some have reached the Oricon top 100 singles and album charts. In 2001, Tamura formed a unit called Yamato Nadeshiko with another well known voice actress, Yui Horie. Two singles were released, Mō Hitori no Watashi and Merry Merrily - the latter of which was an insert song in the Love Hina Christmas Special.
