Rhapsody in August unfolds across Kyūshū and Nagasaki, threading the lives of three generations of a Japanese family as they reckon with the long shadow of the atomic bombing. At the center stands Kane, an elderly woman whose memory is growing unreliable and whose heart still carries the ache of a husband killed in Nagasaki. Her two married children live within postwar Japan, and her brother resides in Hawaii, where his son, Clark, was raised in America. Surrounding Kane are her four grandchildren, visiting the family country home and watching how the past unsettles the present.
This summer, the grandchildren have been asked to persuade Kane to visit her brother in Hawaii. They seize a day to venture into Nagasaki itself, stepping beyond the safety of home to witness the city where their grandfather died in 1945. For the first time, the younger generation begins to feel the emotional undercurrents of that catastrophe, and their perspectives shift as they gain a sharper awareness of the consequences of the atomic bombing. As they bond with their grandmother, a sense of reverence grows, and their questions about morality—especially the United States’ choice to unleash atomic weapons—begin to take shape in their conversations and reflections.
Meanwhile, a telegram arrives from Kane’s American relatives offering a tempting opportunity: their parents would manage new pineapple fields in Hawaii. The message complicates family dynamics, as Kane’s decision to write back about her husband’s death in Nagasaki unsettles her children, who fear how their Americanized relatives might interpret such news. Into this tension steps Clark, who travels from Hawaii to Japan to attend the memorial service for Kane’s deceased husband, seeking reconciliation with his aunt amid the quiet rituals of remembrance.
Clark is deeply moved by the Nagasaki community’s response to loss, especially during the Buddhist memorial ceremony that gathers locals to honor those who perished. Yet the news soon arrives that his own father has died in Hawaii, forcing him to return for another funeral and to confront the fragility of family across oceans and cultures. Back home, Kane’s health and memory begin to falter more visibly. She clings to tangible fragments of the past—stretching out her husband’s old clothing and arranging them as if he might reappear. When a storm brews, she mistakes it for another air raid warning and tries to protect her visiting grandchildren by offering folk remedies, which confound her children and the younger generation. As the storm intensifies, her confusion deepens, and she misreads the tempest as the aftermath of Nagasaki’s blast. In a final, determined surge of memory and love, she takes up a small umbrella and ventures into the storm, walking toward Nagasaki in a desperate bid to shield her husband, still living in her memory, from a danger she cannot forget.
