Trivia, insights & behind the scenes
Based on Fumiyo Kōno's acclaimed manga, part of Japan's ongoing cultural reckoning with Hiroshima's legacy through intimate family stories rather than spectacle.
The title's contrast—'evening calm' versus 'cherry blossoms'—mirrors the film's tension between transient beauty and permanent scars. Minami's name literally means 'beautiful wave,' a cruel irony given her fate.
