Meaning & Definition

Fuku is the verb Japanese reaches for whenever air moves with force, whether that’s the wind sweeping through a street, a person blowing out a candle, or a musician sending breath through a flute. It shows up constantly in weather reports and daily small talk, which makes it one of the first action verbs learners meet after the basics.

Fuku works two ways depending on what’s doing the blowing. When the wind itself is the subject, the sentence is intransitive: 風が吹く (kaze ga fuku) simply means “the wind blows,” with no object needed. When a person blows something, fuku takes an object marked by を: 口笛を吹く (kuchibue wo fuku, “to whistle”) or 笛を吹く (fue wo fuku, “to play the flute”). This second pattern extends to any wind instrument, so トランペットを吹く and ラッパを吹く both mean “to play the trumpet.” A completely unrelated but identically pronounced verb, 拭く (also read fuku), means “to wipe” — 机を拭く is “to wipe the desk.” The kanji make the difference obvious in writing, but in speech only context tells them apart.

How to Use It

The homophone trap runs deeper than the dictionary form: 吹く and 拭く share every conjugated form too, so 吹いた and 拭いた are both pronounced fuita. A sentence like 「窓を吹いた」makes no sense (you don’t “blow” a window), so listeners lean on real-world logic and surrounding words like 風 or 布巾 to sort out which verb is meant — learners should do the same rather than guessing from sound alone. Note also that fuku is a plain godan verb (吹く → 吹きます → 吹いた), not the irregular type, so it conjugates predictably once you know the -く ending pattern. Finally, don’t confuse the instrument use of 吹く with 弾く (hiku, to pluck/play strings like guitar or piano) or 叩く (tataku, to hit, used for drums) — Japanese assigns a different “play” verb depending on how the instrument physically produces sound.

Example Sentences

Cultural Context

In traditional Japanese music, 吹く marks out a whole family of instruments by how they’re played. The 尺八 (shakuhachi, bamboo flute) and 笛 (fue, flute) are both 吹く instruments, distinct from stringed instruments like the 三味線 or 琴, which use 弾く, and drums like the 太鼓, which use 叩く. English flattens all of this into the single verb “play,” but Japanese keeps the physical action — breath, pluck, or strike — built into the verb itself, so naming an instrument’s verb is a quick way to signal how it actually works.

Online, 吹いた has taken on a life of its own as slang for “I burst out laughing” — the idea being that something was so funny you literally blew air out through your nose or mouth in a sudden laugh, rather than laughing normally. It grew out of Japanese forum and bulletin-board culture, where reactions to jokes and memes needed to be short and visceral, and it remains common on social media today as a quick, one-word way to react to something absurd or unexpectedly hilarious — closer to “I lost it” than a plain “lol.”
