Obayashi himself directed and co-wrote a second film based on the same novel, premiered in 2007 and titled Switching: Goodbye Me (転校生－さよなら あなた－, Tenkōsei: Sayonara Anata).

[1] I Are You, You Am Me tells the story of two junior high school students, Kazuo and Kazumi, who accidentally fall down a flight of stairs and inexplicably switch bodies.

The film explores themes of identity, adolescence, and empathy, providing a unique take on the body-swap genre.

Switching: Goodbye Me, the 2007 remake, retains the core plot of the original while updating the setting and characters for a new generation.

Both films are based on the novel by Hisashi Yamanaka and showcase Obayashi's distinctive directorial style, blending whimsical fantasy with heartfelt drama.
