A mangaka who primarily works on Shojo manga. She made her pro debut in 1996 with the one-shot The Style of the Second Love (2番目の恋のかたち, Niban-me no Koi no Katachi), which was later reprinted in the one-shot compilation manga Kanshaku-dama no Yuu'utsu. Tanemura later gained fame less than a year later with the manga I-O-N, a high-school romance (a common staple in the shojo genre) with a supernatural twist.
Her works usually contain Magical Girl stories (with a few exceptions) and extremely cute drawings that are deemed too saccharine for some. Tanemura's distinctive art style was intended to be difficult to animate, but this has not stopped Kamikaze Kaitou Jeanne and Full Moon o Sagashite from being adapted into anime series.
