While the film focuses on sisters, the maternal energy directed toward the rare male characters (like the sickly hospital director) is distinctly Japanese: it is about nurturing without smothering. The deep love is expressed through shared meals, folding laundry, and watching the summer fireworks from a backyard. This is perhaps the most realistic portrayal—love that is not dramatic or tragic, but a persistent, gentle tide that holds the family together. Yojiro Takita’s Oscar-winning Departures features a son’s complex relationship with his absent father, but the mother’s role is a ghostly presence. The protagonist, Daigo, remembers his mother’s love as the only stable force in his childhood. After she dies, he carries her love with him like a talisman.
The protagonist, Akiko, is not the saintly figure of classic cinema. She is hedonistic, broken, and possessive. Yet, in her twisted logic, everything she does—abandoning stability, dating abusive men, teaching her son to steal—is for their survival.

It shows that the intense fusion of mother and son, when devoid of societal structure, can result not in comfort but in codependency and ruin. Critics called it a horror film disguised as a drama, highlighting how the phrase "deep love" can sometimes be a euphemism for a trap.

She is playful and warm, buying them gifts and singing songs. But her “deep love” is ultimately unreliable. One day, she leaves her eldest son, Akira (age 12), to care for the younger siblings, and never returns. japanese mother deep love with own son movies
The “deep love” here is purely narcissistic. She sees her son? No—in this film, the dynamic shifts, but the theme remains: The mother views the child as an extension of her own ego. Her relentless search is not for a lost daughter, but for a lost possession. It is a shocking deconstruction of bosei , suggesting that the intensity of a mother’s love can be indistinguishable from monstrous obsession. Kore-eda returns with a softer, more optimistic take in Our Little Sister . Here, the traditional mother is absent (she has died and been abandoned by her husband). Instead, three adult sisters raise their teenage half-sister, Suzu. The eldest sister, Sachi, acts as the surrogate mother to the boy (or male figure) of the story.
