This acclaimed anime film adaptation of Mei Hachimoku’s novel captivates audiences through its delicate balance of melancholy and wonder, inviting viewers into a world where a mysterious tunnel offers a chance to rewrite the past.

The Tunnel to Summer the Exit of Goodbyes : Synopsis & Core Premise
Set in a quiet coastal town, the story follows Kaoru Tono, a teenager burdened by guilt over his sister’s mysterious disappearance years earlier. He discovers a hidden urashima tunnel—a legendary passage where time flows differently inside than outside. Entering with his classmate Anzu Hanashiro, who harbors her own painful secrets, they experience time distortion where hours inside equal mere minutes in the outside world. As they navigate this temporal anomaly, confronting their pasts while facing the tunnel’s dangerous consequences, the narrative explores how far one might go to alter painful memories and whether some goodbyes are truly necessary for healing.
Themes & Motifs
Time, Memory, and Regret
The tunnel serves as a powerful metaphor for how we process grief and regret, with its time-bending properties reflecting the subjective nature of memory. The film suggests that while we might wish to revisit and change the past, doing so could fundamentally alter who we’ve become. Through Kaoru’s journey, we see how regret can become a prison, yet also how confronting it—rather than escaping it—offers the only true path forward. The narrative poses profound questions about whether erasing painful memories would actually bring peace or merely create different kinds of loss.
Character Dynamics and Growth
Kaoru and Anzu’s relationship evolves from hesitant companionship to profound mutual understanding, their shared vulnerability creating a space for emotional honesty neither has experienced before. Their contrasting approaches to the tunnel—Kaoru’s desperate hope to change the past versus Anzu’s more measured perspective—create compelling tension that drives character development. Supporting characters, including Kaoru’s emotionally distant father and Anzu’s protective friends, provide necessary context that highlights the isolating nature of unresolved grief and the healing potential of genuine connection.
Visual/Atmospheric Storytelling
The film employs breathtaking visual contrasts between the tunnel’s ethereal, dreamlike interior—characterized by soft blues and luminescent flora—and the grounded, sun-drenched realism of the coastal town. Director Tomohisa Taguchi uses light as a narrative device, with the tunnel’s shifting illumination reflecting the characters’ emotional states. Sound design plays an equally crucial role, with the muffled silence inside the tunnel emphasizing its otherworldly nature, while the film’s minimalist piano score underscores moments of revelation without overwhelming the emotional weight of each scene.
