A Terminal Trust (終の信託, Tsui no Shintaku) is a 2012 Japanese drama film directed by Masayuki Suo and starring Tamiyo Kusakari, Koji Yakusho, Takao Osawa and Tadanobu Asano. It is Suo's first fiction film since I Just Didn't Do It (2006).

Mark Schilling of The Japan Times said, "Expect something thoughtful, informed — and utterly unlike the usual sob-fest Japanese medical melodrama." James Hadfield of Time Out said, "Trust director Masayuki Suo to reunite the stars of his most popular film for a cheery romantic drama about assisted dying. Shall We Dance? leads Tamiyo Kusakari and Koji Yakusho play a doctor and her terminally ill patient, with a support cast including Tadanobu Asano and Takao Osawa." Hugo Ozman of Twitch Film described the film as "a thought-provoking film that will please viewers who like serious dramas" and "a beautiful film with deep meanings and some of the best performances in a Japanese film this year." However, John Defore of The Hollywood Reporter said, "It's understandable Suo would want to give so much screen time to the highly sympathetic Yakusho, but doing so doesn't serve the dramatic structure of a film that might've been much more provocative than it is."

Shinzo Egi (Koji Yakusho) is an asthma sufferer who does not want to be place on life support. As a last request, Shinzo Egi asks his doctor Ayano Orii (Tamiyo Kusakari) if she could follow his wish. Doctor Ayano Orii is then questioned in a criminal case because of her decision.
