Star-crossed romance has long been a staple in Japanese cinema, though medical catastrophe, more than a disapproving society or opposing parents, has become a common force tearing lovers apart in contemporary films. This does not always mean a tragic finale: In Takahisa Zeze’s 2017 hit “The 8-Year Engagement,” the heroine recovers from a long coma to wed her devoted fiancee.

Eiji Uchida’s “Silent Love” adds a twist to this staple trope — both principals are afflicted with disabling conditions: Mika (Minami Hamabe) is an aspiring pianist who was blinded in a traffic accident, and Aoi (Ryosuke Yamada), a custodian at Mika’s music college, is mute from a wound incurred in a street brawl.
