The first tankōbon volume was released by Enterbrain in July 2003 in Japan; as of December 2010, 11 volumes have been released.

Plot
The story depicts a young boy named Shūichi Nitori who wants to be a girl, and his friend Yoshino Takatsuki, a girl who wants to be a boy. The series deals with issues such as transsexuality, gender identity, and the beginning of puberty. Shimura was originally going to write the story about a girl in high school who wants to be a boy, but she realized that a boy who wants to become a girl before entering into puberty would have a lot of worries related to growing up, and changed the story to fit this model. Wandering Son was selected as a recommended work by the awards jury of the tenth Japan Media Arts Festival in 2006. The series has been lauded for its use of gender reversal as the core of the story, though the emotional realism of the young characters has been called into question.
