Takako Shimura is a Japanese manga artist born on October 23, 1973, in Kanagawa Prefecture and currently resides in Tokyo. She made her professional debut in 1997 with the short story Boku wa, Onna no Ko, published in the manga magazine Comic Beam. This initial work introduced themes of gender and identity that would become central to her subsequent career.

Shimura is primarily known for creating manga that explore LGBT topics, particularly those involving lesbian relationships and transgender experiences. Her most acclaimed and commercially successful series are Sweet Blue Flowers (Aoi Hana) and Wandering Son (Hourou Musuko). Sweet Blue Flowers, which depicts the romantic relationships between high school girls, was serialized from 2004 to 2013 and compiled into eight volumes. It was adapted into an 12-episode anime television series that aired in 2009. Wandering Son, a series following two elementary school children navigating gender identity and the desire to live as the opposite sex, ran from 2002 to 2013 across fifteen volumes. This series received an anime adaptation that aired in 2011.

Beyond her original manga series, Shimura has contributed to the anime industry in other capacities. She provided the original character concepts for the 2014 original anime series Aldnoah.Zero and served as the character designer for the 2016 anime adaptation of the novel Battery. Her manga works that have been adapted into anime include the short story collection Happy-Go-Lucky Days (Dou ni ka Naru Hibi), which was released as an animated film in 2020, and Awajima Hyakkei, a series serialized from 2011 to 2024 that follows students at a theatrical school, which has also been adapted into an anime.

A consistent element of Shimura’s artistic identity is her focus on psychological realism and the nuanced portrayal of adolescent struggles with sexuality and gender identity. Her narratives often avoid clear resolutions or ideological advocacy, instead emphasizing the internal conflicts, hesitation, and gradual development of her characters as they interact with social norms and physiological changes like puberty. This approach has earned her acclaim for creating sensitive, character-driven stories that treat queer experiences with subtlety and depth. Her artistic style has evolved over time from a more unpolished look to a gentler, more refined aesthetic while maintaining a focus on realistic character designs.

In addition to her published work, Shimura has been active in amateur manga (doujinshi). In 2009, she formed a doujinshi circle named Harapeko Sentai Hashi Ranger with fellow manga artists Hisae Iwaoka, Fumiko Tanagawa, Aoki Toshinao, and Ishide Den. Her significance in the industry lies in her pioneering role in bringing nuanced LGBT narratives to a wide audience through critically acclaimed manga and their subsequent anime adaptations, establishing her as a key creator in the genre.
