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 ''[[{{Manga/ION}} I-O-N]]'', a high-school romance (a common staple in the shojo genre) with a supernatural twist.

Her works usually contain MagicalGirl stories (with a few exceptions) and extremely cute drawings that are deemed [[TastesLikeDiabetes too saccharine]] for some, juxtaposed against frequently dark and angsty storylines that deal with issues like [[DrivenToSuicide suicide]], {{parental abandonment}}, and {{attempted rape}}. Tanemura's distinctive art style was intended to be difficult to animate, but this has not stopped ''Manga/KamikazeKaitouJeanne'' and ''Manga/FullMoonOSagashite'' from being adapted into anime series.

She is a known fan of {{JPop}} music, especially HelloProject artists and Creator/MaayaSakamoto. This factor has turned now into a PromotedFangirl fact, as she's recently provided the character designs for the multimedia idol project ''VideoGame/Idolish7''.

As of 2015, Tanemura also releases doujinshi under the pseudonym [[http://twitter.com/meguro_arina Arina Meguro]].
