Japanese film director Ogigami Naoko's first film in five years Karera ga Honki de Amutoki wa,(When they knit seriously) focuses on an unconventional family that includes a transgender woman played by Toma Ikuta.

“Now that filming has started, I realized that this role is very difficult," Ikuta told Arama Japan. "But it is rare to receive an opportunity to play this kind of role, so I have been doing my best."

Here's a synopsis of the film:

"11-year-old Tomo (Rinka Kakihara) lives with mother Hiromi (Mimura), but Hiromi decides to give up on her and leaves their home. Tomo, now all alone, visits her uncle Makio's (Kenta Kiritani) home. Makio lives with his beautiful girlfriend Rinko (Toma Ikuta). Rinko was born as a man and now works as a caregiver at a home for the elderly. Tomo is a little confused by the situation, but they begin to live as a family."

The movie was inspired by a 2013 newspaper article about a mother of a transgender daughter who makes fake breasts for the daughter.

The film opens in Japan on February 25, 2017. As of now there is no U.S. release date.
