Meaning
The kanji 拳 means fist or knuckle — the tightly clenched hand formed when fingers curl inward against the palm. The structure makes its meaning legible at a glance: the upper component 龹 depicts curved, bent fingers, while the lower component 手 (hand) anchors the image below. Together, they portray a hand whose fingers have folded downward — exactly the motion of making a fist.
Etymologically, 拳 is a compound ideograph (会意文字, kaiimoji). Ancient oracle bone scripts show a hand with fingers bent at the knuckles, and over centuries this evolved into the modern form. The character was always tied to the physical act of clenching — whether in fighting, protest, or fierce emotion.
Few body-part kanji carry as much symbolic weight as 拳. Raising a clenched fist (拳を振り上げる) signals defiance, solidarity, or triumph depending on context. In martial arts — karate, kung fu, boxing — the fist is the primary weapon, making 拳 essential vocabulary in those disciplines. Beyond combat, 拳 appears prominently in the compound 拳銃 (pistol), a word derived from the idea of a weapon small enough to hold in a fist.
拳 has 10 strokes and is classified at grade 8 (high school and above) in the official Japanese curriculum. It was formally added to the revised Jōyō Kanji list in 2010, reflecting its steady presence in news reports, martial arts writing, crime fiction, and everyday speech.
Readings
On'yomi (音読み) — Chinese-derived readings
拳 has one on'yomi: ケン (ken), drawn from Middle Chinese. It appears almost exclusively in compound words (熟語, jukugo) — formal writing, martial arts terminology, news reports on weapons, crime fiction. In everyday speech, Japanese speakers reach for the kun'yomi こぶし instead.
- 拳法 (kenpō) — martial art using the fists; Chinese boxing; a style of kung fu
- 拳銃 (kenjū) — pistol; handgun (literally "fist gun" — compact enough to fit in one hand)
- 鉄拳 (tekken) — iron fist; an exceptionally powerful punch
- 拳闘 (kentō) — boxing; pugilism (a somewhat literary or older term for the sport)
- 拳士 (kenshi) — martial arts practitioner; fighter (especially in Shorinji Kempo)
Kun'yomi (訓読み) — Native Japanese readings
The kun'yomi is こぶし (kobushi) — the native Japanese word for fist. It appears when 拳 stands alone or inside Japanese-origin phrases. こぶし is what you hear in everyday speech: someone clenching a fist in frustration, throwing a punch, or raising an arm in triumph. Worth knowing: こぶし (辛夷) also names a spring magnolia in Japanese, though that sense uses entirely different kanji. The word 拳骨 (げんこつ, genkotsu) is an irregular reading to memorize separately — it describes a blow delivered with the bare knuckles.
- 拳 (kobushi) — fist (standalone use, everyday speech)
- 拳骨 (genkotsu) — knuckle punch; a blow delivered with the bony part of the fist (irregular reading)
- 拳を握る (kobushi wo nigiru) — to clench one's fist (a key expression of determination or anger)

Memory Tip
To remember 拳, start with its structure. The bottom is 手 (hand) — a kanji most learners encounter early. The curving strokes above represent four fingers bending downward, curling toward the palm. The whole character shows a hand with fingers folded in: a fist, drawn in kanji. For the on'yomi ケン (ken), think of the English word can: "I can punch — that's my ken!" For the kun'yomi こぶし (kobushi), picture a traditional Japanese folk singer belting out a melody with one fist raised high. That raised, passionate fist — that is a kobushi. Connect that image to the kanji's shape and the word locks in.
