What Is “If I Had a Stroke”?

“If I Had a Stroke” is a human drama film based on a true story scheduled for nationwide release on Saturday, December 20, 2025.
Written and directed by Takafumi Ota, known for works such as “Bridge Over Tomorrow” and “Blue Blue Sky.”
The film is a moving piece based on his own battle with stroke, exploring the question “What would happen if I collapsed?”
It stars Shunsuke Kubozuka, with a strong supporting cast including Takemi Fujii, Tomoko Fujita, Misato Tanaka, and Shiro Sano.

Basic Info

The story follows a film director protagonist who suddenly suffers a stroke. While struggling with speech impairment, visual impairment, and memory issues, he finds his way back to a renewed “meaning of life.”
Amid feelings of loneliness, anxiety, and social disconnection, he gradually regains hope through interactions with those around him, delivering a message to contemporary society about life and bonds.

Reality Born from Director Takafumi Ota’s Personal Experience

Director Ota himself suffered a stroke, at one point losing his ability to speak and nearly his sight.
This film visualizes the “reality that help doesn’t always reach you even when you ask” and “the preciousness of human connection” that he felt during that grueling battle.
While realistically depicting social media, medical settings, and family relationships, it offers a chance to reconsider human kindness and rebirth.

Shunsuke Kubozuka’s Overwhelming Performance

Lead actor Shunsuke Kubozuka delivers a powerful performance as Ryutaro Otaki, the protagonist battling the aftereffects of a stroke.
His acting conveys the frustration of a body that won’t move and words that won’t come, relying on expression alone and earning acclaim.
The supporting cast—Tomoko Fujita and Misato Tanaka among them—adds depth, crafting a memorable human drama.

Synopsis & Production Details

“If I Had a Stroke” is a moving story that portrays a “sudden illness” that could happen to anyone, and the weakness and strength of being human that appear because of it.
The protagonist is Ryutaro Otaki (played by Shunsuke Kubozuka), a single man working as a film director.
Busy with work and putting health checkups on the back burner, he suddenly collapses from a stroke one day.

After collapsing, his vision doubles and words won’t come out as he intends.
He desperately seeks help on his smartphone, but no one takes him seriously.
In loneliness, he deeply reexamines “the meaning of life” and “the value of helping one another.”—

Core of the Story: A Tale of Isolation and Renewal

The first half focuses on the onset of the stroke and the grueling early rehabilitation.
With meticulous attention to symptoms like aphasia, visual impairment, and paralysis, the film has a reality that makes you think, “What if it were me?”
From the middle, through encounters with people who support him, he slowly regains hope.
Reflecting contemporary issues like misunderstandings and isolation on social media, it portrays a strong will to “live on regardless”.

Director’s Message: The Sanctity of Life and the Shape of Society

In interviews, Director Takafumi Ota has said, “Stroke isn’t a special illness; it can happen to anyone.”
The film carries his warnings about social isolation felt during his treatment, challenges in medical settings, and a strong desire to convey the importance of life.
Throughout the work, it encourages viewers to “reconsider the health and way of life of themselves and their loved ones.”

Tone and Directing Style

True to Ota’s reputation for visual beauty, the warm lighting and quiet music are memorable.
Despite its heavy theme, it never turns bleak; instead, it’s rendered in a gentle tone that conveys renewal and hope.
Casual conversations among characters are sprinkled with “hints for mutual support,” leaving hearts warmed after the credits roll.
