The Kanji at a Glance
Japanese has two common kanji for life, and choosing between them changes what you are saying. Anyone who tells you there is one correct answer is skipping the part that matters.
命 (inochi) is life as a possession and a span. The thing you can save, risk, or lose.
- On’yomi: MEI, MYOU
- Kun’yomi: inochi
- Strokes: 8
- Core meaning: life, life force, fate, command
生 (sei) is life as activity. Living, growing, being born, being fresh and unfinished.
- On’yomi: SEI, SHOU
- Kun’yomi: i(kiru), u(mareru), nama, ha(eru)
- Strokes: 5
- Core meaning: life, birth, living, raw
Meaning and Nuance
命 leans grave. It is the word a doctor uses, the word in a war memorial, the word for the single life you were given. Its secondary sense of command or decree comes from the same root idea of something handed down to you.
- 生命 (seimei) is life in the biological sense, as in 生命体, a living organism.
- 運命 (unmei) is fate or destiny, literally the life that is carried along.
- 一生懸命 (isshoukenmei) means giving something everything you have, staking your whole life on it. It is one of the most used phrases in spoken Japanese.
生 is broader and lighter. It shows up everywhere because it covers living, producing, and rawness all at once.
- 人生 (jinsei) is a human life, a lifetime, the shape of your years.
- 生活 (seikatsu) is daily life, the practical business of living.
- 学生 (gakusei) is a student, someone in the middle of growing.
- 生 (nama) on its own means raw or fresh, as in 生ビール, draft beer.
That last one is worth pausing on. The same character that means life also means uncooked. Context sorts it out for Japanese readers, but a lone 生 on skin does not come with context.
As a Tattoo
Pick 命 if you mean the weight of a life. Pick 生 if you mean the act of living. That is the honest short version.
命 is the more common tattoo choice and the safer one for meaning. Eight strokes with a strong roof element on top give it a solid, grounded silhouette that holds up at medium and large sizes. Its gravity is the point, and it is often chosen after loss or survival.
生 is visually cleaner at five strokes, but it is the one with a translation risk. Standing alone with no surrounding word, a Japanese reader may well see “raw” before “life,” in the same way an English speaker seeing “draft” thinks of beer or a document depending on where it is written. Nobody will be confused about your intent for long, but you should know the reading exists.
Both characters are written identically in Japanese and simplified Chinese, so there is no script conflict to navigate here.
For placement, 命 suits the forearm, ribs, and upper back, anywhere it can be read cleanly at a reasonable size, because the internal strokes crowd if it is shrunk too far. 生 tolerates small placements better.
If a single character feels too flat, the compounds carry more: 一生懸命 (isshoukenmei) for wholehearted effort, or 生き様 (ikizama) for the way a person lives. Confirm with a native speaker before you ink.

FAQ
What is the kanji for life?
There are two. 命 (inochi) means life as something you possess and can lose, and also means fate or command. 生 (sei) means life as living, birth, and growth. 命 has eight strokes, 生 has five, and both are standard modern Japanese.
Should I get 命 or 生 tattooed?
Choose 命 for the weight and preciousness of a life, which is the usual intent behind a “life” tattoo. Choose 生 for the ongoing act of living. Be aware that 生 alone can also read as raw or fresh, since it is the character on draft beer taps across Japan.
What does 一生懸命 mean?
It means doing something with everything you have, literally staking your whole life on it. It is a four-character phrase used constantly in daily Japanese, from sports to schoolwork, and it is a popular tattoo choice for people who want more than a single character.
Is 命 the same in Chinese?
Yes. 命 is written identically in Japanese, simplified Chinese, and traditional Chinese, and carries closely related meanings of life, fate, and command in all of them.
