All 5 Best Natsuki Deguchi Movies Ranked (Best to Worst)

Director Takahiro Miki brings delicate, painterly framing to what could have easily devolved into a routine terminal-illness romance. By focusing on how limited time sharpens sensory beauty—autumn ginkgo leaves, hospital terrace sunsets, and the frantic creation of finished art—the picture avoids cheap manipulation in favor of sincere, lingering melancholy. As Haruno, a high school girl facing a six-month prognosis, Deguchi provides the picture's vital pulse. Rather than leaning into fragile, tragic clichés, she radiates a stubborn, wry vitality that gives weight to the central bond. It stands as her definitive feature breakthrough, demonstrating rare control over subtle tonal shifts between youthful defiance and quiet mortality.

Adapting Tatsuki Fujimoto’s celebrated meditation on creative obsession and sudden grief requires an intimate, razor-sharp rhythm. The narrative thrives on artistic rivalry blossoming into profound kinship, capturing the punishing solitude of desk-bound cartoonists whose shared ambitions transform childhood isolation into vivid creative synchronicity before tragedy strikes. Stepping into this fiercely scrutinized adaptation, Deguchi brings nuanced vulnerability to her role, capturing the delicate friction between creative envy and unvarnished adoration. Her restraint prevents the film's poignant climax from descending into melodrama, solidifying her standing as a versatile performer capable of handling high-stakes source material with poise and psychological accuracy.

Hiroshi Nishitani’s polished return to the Keigo Higashino mystery universe relies on intricate plotting and the communal trauma of a tight-knit neighborhood festival. The procedural momentum builds not merely on forensic deductions by Masaharu Fukuyama's iconic physicist, but on the enduring collective grief surrounding a murdered local singer whose disappearance fractured a small town. Deguchi embodies that central phantom as Saori Namiki, appearing primarily through memories and flashbacks. She infuses the murdered girl with radiant, effervescent charm, ensuring that Saori never feels like a disposable plot device. It is an economical yet haunting showcase that anchors the moral stakes of the entire investigative ensemble.

Yoichi Narita’s time-travel wartime drama leans heavily on high-concept emotional friction, sending a disillusioned modern teenager back to the twilight months of World War II. While the pacing occasionally stumbles beneath period melodrama, the film's visual reverence for rural Japanese landscapes and the looming dread of kamikaze squadrons lend palpable historical weight to its romance. Appearing as Chiyo, a loyal local girl working alongside the protagonist at a wartime diner, Deguchi supplies essential warmth to the somber domestic sequences. Her bright, unfussy naturalism acts as an emotional counterweight to the surrounding tragedy, adding another grounded period credit to her expanding cinematic repertoire.

Adapting Kaiu Shirai’s dark fantasy manga into live-action yields an intriguing, if uneven, gothic thriller. While director Yuichiro Hirakawa effectively recreates the lush, sinister confines of Grace Field House and its lurking monstrous reality, the film frequently struggles with tonal dissonance, caught awkwardly between cartoonish villainy and genuine psychological peril. Playing Gilda, the pragmatic glasses-wearing orphan, Deguchi delivers steady, capable supporting work despite limited screen time. While the adaptation's rapid pacing leaves little room to explore her character's internal doubts, her composed physical acting and alert expressions convey genuine loyalty, marking an early milestone in her transition from commercial modeling to full-scale screen acting.
