๐Ÿ“– Plot Summary

Three sisters—Sachi, Yoshino, and Chika—live together in their grandmother's house in Kamakura, a quiet coastal town near Tokyo. Their lives follow a gentle rhythm: work, shared meals, occasional bickering, and the steady presence of the sea.

When their estranged father dies, they travel to his funeral and meet Suzu, their 14-year-old half-sister. Despite the complicated history—their father left them years ago for Suzu's mother—the three sisters invite Suzu to live with them.

What follows isn't a story of dramatic reconciliation or explosive emotions. Instead, Our Little Sister quietly observes how four women, connected by blood but separated by circumstances, slowly become a family. Through cherry blossom viewings, homemade plum wine, and small acts of kindness, they learn to forgive the past and embrace the present.

Hirokazu Kore-eda, known for his tender explorations of family (ShopliftersStill WalkingNobody Knows), once again crafts a film that feels less like fiction and more like a gentle documentary of daily life.


๐ŸŒŠ Key Themes

Family Beyond Blood

The film questions what makes a family. Is it shared DNA? Shared history? Or is it something simpler—choosing to care for one another, day after day?

Suzu arrives as a reminder of betrayal, yet the sisters welcome her without resentment. This quiet generosity becomes the film's moral center.

Forgiveness Without Drama

Unlike most family dramas, Our Little Sister doesn't build toward a cathartic confrontation. There's no screaming match, no tearful confession scene. Forgiveness happens gradually, almost invisibly—in a shared meal, a gentle touch, a walk by the sea.

The Healing Power of Routine

Cooking, eating, cleaning, working—the film elevates mundane rituals into acts of love. Kore-eda's camera lingers on hands kneading dough, chopsticks lifting noodles, sisters walking side by side. These small moments become the fabric of connection.

Kamakura as Sanctuary

The seaside town of Kamakura is more than a backdrop—it's a character. The ocean's steady rhythm mirrors the film's pacing. Cherry blossoms bloom and fall, marking time's passage. The town itself feels like a refuge from the noise of Tokyo, a place where wounds can heal slowly.


๐Ÿ’ญ Personal Reflection

This film has so many potential conflicts—abandonment, betrayal, resentment, loss.

In most movies, these would explode into dramatic confrontations. But here, they simply... exist. And somehow, that feels more real. The sisters don't resolve everything through tears and apologies. They just keep living, together. And in that quiet continuity, healing happens.

Watching them navigate conflict without chaos—just gentle honesty, patient understanding, and time—I felt my own shoulders relax. Maybe that's what we need sometimes. Not grand resolutions, but the calm steadiness of showing up for each other, day after ordinary day.

Life's waves can be unpredictable, but eventually, the calm waters gather us back to shore.


๐ŸŽฌ What Makes This Film Special

Hirokazu Kore-eda's Signature Style

Kore-eda is a master of observational cinema. He doesn't manipulate emotion—he simply watches, with patience and compassion. His films feel unhurried, trusting the audience to find meaning in silence and stillness.

In Our Little Sister, he uses long takes, natural light, and ambient sound to create an immersive, meditative atmosphere. The camera rarely intrudes; it simply witnesses.

The Four Sisters

Each sister carries her own quiet burden:

  • Sachi (Haruka Ayase): The responsible eldest, weighed down by duty and guilt
  • Yoshino (Masami Nagasawa): The middle sister, navigating love and independence
  • Chika (Kaho): The free spirit searching for purpose
  • Suzu (Suzu Hirose): The bridge between past and present, innocent yet perceptive

Their chemistry feels authentic, not performed. They argue, tease, comfort, and coexist like real siblings.

Visual Poetry

Cinematographer Takimoto Takashi captures Kamakura's beauty without sentimentality. Cherry blossom tunnels, sunlit kitchens, the shimmer of the sea—every frame feels painterly yet grounded.

The famous tunnel scene, where the sisters walk beneath falling petals, could have been cloying. Instead, it's transcendent—a moment of shared grace.

Food as Connection

Like many Japanese films, Our Little Sister treats cooking and eating as sacred acts. The sisters make plum wine from their grandmother's recipe, share whitebait toast at the local cafรฉ, prepare meals together in their cramped kitchen.

Food becomes memory, tradition, and love made tangible.


๐ŸŒธ The Meaning of the Sea

The ocean in Our Little Sister is ever-present—sometimes calm, sometimes restless, always there.

It mirrors the sisters' emotional landscape: steady beneath the surface, occasionally turbulent, but fundamentally constant. The sea doesn't judge or demand. It simply exists, offering space for reflection and renewal.

By the film's end, the sea has become home—not a place of escape, but of belonging.

๐Ÿ“ Final Thoughts

Our Little Sister doesn't shout. It whispers.

It reminds us that not all conflicts require dramatic resolutions. Sometimes, healing happens in the space between words—in a shared glance, a hand on a shoulder, the simple act of making breakfast together.

Kore-eda trusts us to sit with these women, to feel their quiet joys and sorrows, without needing every emotion explained or amplified. In a world of noise, this restraint feels radical.

The film's final image—four sisters walking toward the sea—is both an ending and a beginning. They carry their grief, their joy, their imperfect history. But they carry it together.

And that, the film suggests, is enough. ๐ŸŒŠ
