Meaning & Definition

決める (kimeru) is one of those verbs that pulls double duty in Japanese — it means ‘to decide’ in everyday planning, but it also carries a vivid colloquial sense of nailing something perfectly, whether that’s a sharp outfit, a bold move, or a power pose delivered with total confidence.

At its core, 決める means to decide on something or to determine a course of action. The most common pattern is 〜を決める (to decide something) — for example, 場所を決める (to decide on a place) or 日程を決める (to set a schedule). When choosing between options, Japanese speakers often use 〜に決める (to settle on ~), as in これに決めた！ (‘I’m going with this!’). Its intransitive partner 決まる (kimaru) means ‘something is decided’ — note the transitive/intransitive distinction: you 決める a plan, and then the plan 決まる. The passive form 決められる appears in formal or workplace contexts when rules or conditions are imposed from above. The negative 決められない (can’t decide) is a staple of everyday conversation for the chronically indecisive. Beyond decision-making, 決める has a vivid stylistic meaning: to pull something off flawlessly — a look, a pose, a dramatic line — with polish and self-assurance. This usage is common in fashion, sports, and performance contexts.

How to Use It

The transitive/intransitive pair is one of the most important things to pin down with this verb: 決める (kimeru) requires a subject who actively decides, while 決まる (kimaru) describes something that gets decided, often without a named agent — useful for softening responsibility in Japanese workplace communication. Two compound words worth memorizing: 決め台詞 (kimezerifu) refers to a signature catchphrase or finishing line someone delivers at just the right moment with full dramatic effect; 決めポーズ (kimepose) is the triumphant or stylized pose struck at a moment of peak flair. Both reflect the verb’s aesthetic dimension — deciding isn’t just practical in Japanese, it can be an act of self-expression.

Kanji Breakdown

The kanji 決 combines the water radical 氵 with 夬, a character meaning to part or split apart. The original image was of water bursting through a dam — a sudden, irreversible breakthrough. That sense of a decisive, point-of-no-return moment is baked into the character itself, giving 決める a subtle weight that goes beyond a casual ‘maybe.’ When you 決める something, you’re not hedging — you’re committing.

Example Sentences

Cultural Context

In Japanese pop culture and public life, the concept of 決め台詞 (kimezerifu) — a signature line delivered at a pivotal moment — carries genuine cultural weight. Politicians, athletes, and public figures are remembered as much for their kimezerifu as for their actions. The phrase is timed for maximum impact: after a long buildup, at the climax of a speech, or just as tension peaks. Japan’s theatrical tradition, from kabuki to modern variety TV, has long celebrated the performer who knows exactly when and how to land their defining line. A well-executed kimezerifu signals not just confidence but a mastery of timing, a quality deeply admired in Japanese social and performance contexts.

Equally embedded in visual culture is 決めポーズ (kimepose) — a signature pose struck at a moment of triumph, self-presentation, or stylized flair. The concept shows up across sentai TV programs, where entire teams freeze mid-action in coordinated poses, as well as in idol group choreography, martial arts demonstrations, and sports victory celebrations. What makes 決める the right verb here is its sense of intentionality and completeness: the pose isn’t just struck, it’s landed perfectly, the way a gymnast sticks a dismount. This aesthetic use of 決める reveals how deeply the verb is tied to the Japanese appreciation for form, precision, and the satisfaction of getting something exactly right.
