Thomas no Shinzō (Japanese: トーマの心臓, Hepburn: Tōma no Shinzō, "The Heart of Thomas" or "Thomas' Heart") is a shōjo manga by Moto Hagio published in 1974. It is an early example of shōnen-ai. It has been adapted into a film, Summer Vacation 1999, and a stage play. In September 2011, Fantagraphics announced that it had been licensed for English release; the single-volume hardcover omnibus, translated by Matt Thorn, was released in January 2013.

Characters

Development
Although Hagio had previously been exposed to the gay lifestyle magazine Barazoku, Hagio was inspired by Les amitiés particulières to begin The Heart of Thomas as a work for her own enjoyment, and soon afterwards wrote November Gymnasium as a work to be published. At one point, Hagio considered making the protagonists girls, and drew a few scenes in a sketchbook, but decided that the boys version was "smoother" and less "giggly". When it was serialised, Thomas no Shinzo was unpopular, so Hagio's editors asked her to finish the manga up quickly, but due to the success of Poe no Ichizoku in the new bound format, Thomas no Shinzo was allowed to continue.
Themes

In an interview, Hagio said that she felt the theme might be "When does a person learn love? When does one awake to love?"
Prequel
A prequel manga was written called The Visitor (訪問者).
Film

The film Summer Vacation 1999 (1999年の夏休み, directed by Shusuke Kaneko and released in 1988, was based on The Heart of Thomas, and the parts were played by girls as breeches roles, using male speech. The character in the film analogous to Thomas was renamed Yuu, and the analogue to Eric was renamed Kaoru, a gender-neutral name. The film was subsequently novelised.
Stage
Studio Life, a Japanese all-male theatre troupe suggested, in approximately 1995, that they stage a production of The Heart of Thomas. As of 2005, it had been staged twice.
Reception
Matt Thorn considers The Heart of Thomas to be about a "spiritual or mental love", and that Hagio's later work A Savage God Reigns is the "adult version" of The Heart of Thomas. Bill Randall notes Hagio's creation of several shōjo manga conventions such as the use of angelic wings. Midori Matsui interprets the manga in terms of Freudian theory and regards the relationships between the characters as indicating that they live in a "closed oedipal universe as fragmented personae of the narcissistic ego". For James Welker, the key theme is love, describing its depiction as "beautiful, if at times traumatic", looking at its role in the key characters' lives.
