The narrator functions as both structural framework and thematic guide throughout the film, transitioning between vignettes of family life. This voice introduces segments with framing titles like "Father as Role Model" or "Patriarchal Supremacy Restored." Its primary role involves reciting haiku poetry, predominantly by 17th-century Japanese poet Matsuo Bashō, to conclude or reflect on each vignette. These haikus juxtapose the family’s mundane struggles with natural and seasonal imagery—such as "How cruel, / a grasshopper trapped / under a warrior’s helmet" following the father’s confrontation with a motorcycle gang.

Detached yet contextualizing, the narration elevates personal experiences into universal meditations on human existence. Haikus like "The scent of plums on a mountain path. Suddenly dawn" accompany adolescent joy, while "No sign of death’s approach in the cicadas’ voices" underscores a grandmother’s hospital visit. Ordinary moments—arguments over chores, parental worries, generational exchanges—transform into reflections on impermanence, resilience, and time’s passage.

Structurally, the haikus operate as cinematic "pillow shots," creating reflective pauses between episodes. They provide narrative closure to individual segments while weaving disparate vignettes into a cohesive exploration of kinship. The narrator remains undeveloped as a character, possessing no personal backstory, instead serving as a consistent omniscient presence. Through cultural and poetic lenses, this voice frames the film’s examination of family dynamics.
