有 — To Have, To Exist

Meaning

The kanji 有 carries the fundamental meaning of to have, to exist, or possession. It is one of the most essential kanji in everyday Japanese, appearing in hundreds of compound words and expressions across every level of the language. Whether you are talking about owning something, something being available, or something simply existing in the world, 有 is the character behind all of it.

Etymologically, 有 is a pictograph. The upper portion derives from 又 (mata), an ancient depiction of a hand or arm, while the lower portion is 月 (tsuki), which in this context represents flesh or meat rather than the moon. The original image is of a hand holding a piece of meat — a vivid, primal expression of possession. Over centuries, this evolved into the abstract concept of having or owning anything at all.

有 has 6 strokes and is taught in Grade 3 of Japanese elementary school, meaning native speakers learn it around age 8–9. It belongs to the radical group 月 (the flesh/moon radical), which appears in many body

and existence-related kanji — a useful anchor when you encounter unfamiliar characters in this family.

In Vietnamese, this kanji corresponds to the Hán-Việt reading HỮU (hữu), which appears in words like hữu ích (useful/beneficial) and hữu nghị (friendship), reflecting the deep historical connection between Chinese characters and Vietnamese vocabulary.

Readings

On'yomi (音読み) — Chinese-derived readings

有 has two on'yomi readings: ユウ (yū) and the less common ウ (u). ユウ dominates modern Japanese compounds, while ウ survives mainly in the set phrase 有無 and a handful of formal or classical expressions.

有名ゆうめい (yūmei) — famous, well-known. Literally "having a name," this compound is one of the first you will encounter as a learner.

有効ゆうこう (yūkō) — valid, effective. Used for tickets, contracts, medicines — anything that "has effect."

有料ゆうりょう (yūryō) — paid, for a fee (as opposed to 無料, free of charge). You will see this on parking signs, toll roads, and subscription services.

有無うむ (umu) — existence or non-existence; yes or no. This is the classic ウ reading, still common in business and formal speech: 参加の有無をお知らせください (Please let us know whether you will participate).

Kun'yomi (訓読み) — Native Japanese readings

The kun'yomi is あ.る (a.ru), where the dot indicates the okurigana (the hiragana that follows the kanji when writing). This gives us the common verb ある, meaning "to exist" or "to have" for inanimate objects and abstract things. A beginner asking 「トイレはありますか？」 (Is there a toilet?) and a JLPT N1 candidate reading a formal contract will both reach for this verb.

有るある (aru) — to exist, to have (for things). お金がある (I have money). 問題がある (There is a problem).

有り難いありがたい (arigatai) — grateful, thankful. Literally "it is difficult to exist" — something so rare or precious that its very existence is remarkable. This is the source of ありがとう (thank you)!

有り得るありえる (arieru) — possible, conceivable. Also written ありえない (impossible, unbelievable) — a word beloved by modern Japanese youth.

Memory Tip

Picture a hand (又) gripping a juicy piece of meat (月). That is the original meaning of 有 — to physically possess something. Whenever you see this kanji, imagine someone tightly clutching something they own and refusing to let go. The top part looks like a bent arm reaching down, and the bottom is the prize being held. That image tends to stick. Worth noting too: ありがとう (thank you) traces back to ありがたい, meaning "this existence is precious and rare" — so every time you say thank you in Japanese, you are using 有.
