Meaning
The kanji 幸 means happiness, good fortune, and luck. It appears everywhere in Japanese — from personal names to everyday expressions of gratitude and well-wishing. When Japanese people wish each other well, this character sits at the heart of those phrases.
Its origin is unexpected. In ancient Chinese oracle bone script, the character depicted a type of handcuff or shackle used on prisoners. A person condemned to death who managed to survive — who narrowly escaped execution — was considered extraordinarily lucky. That narrow escape from misfortune became the seed of the concept of good fortune. Over centuries, this evolved from mere survival luck into the broader, warmer sense of happiness and blessing the character holds today.
Visually, 幸 is written in 8 strokes and falls under the radical 干. It is taught in the third grade of Japanese elementary school, so native speakers learn it around age 8–9. Despite its modest stroke count, the character shows up in some of the most important words in Japanese — from the everyday 幸せ to formal expressions of good fortune. For learners heading toward intermediate and advanced Japanese, recognizing 幸 is essential.
Readings
On'yomi (音読み) — Chinese-derived readings
The on'yomi reading of 幸 is コウ. This reading appears in formal compound words (熟語, jukugo) of Chinese origin and comes up frequently in written Japanese — newspapers, official documents, literature, and formal speech. The コウ reading tends to feel more elevated or abstract than the native Japanese readings.
Key compound words using the コウ reading:
- 幸福 (kōfuku) — happiness, well-being, bliss. The most formal and philosophical word for happiness, used in contexts from psychology to wedding speeches.
- 幸運 (kōun) — good luck, fortune. Used when wishing someone luck or describing fortunate circumstances.
- 不幸 (fukō) — unhappiness, misfortune, ill fate. The negative prefix 不 (fu) flips the meaning entirely.
- 多幸 (takō) — great happiness, abundant blessings. Often found in formal written greetings.
- 薄幸 (hakkō) — unhappy fate, unfortunate life. A literary, somewhat melancholy term.
Kun'yomi (訓読み) — Native Japanese readings
The kanji 幸 has three native Japanese (kun'yomi) readings, each with a slightly different nuance and usage context.
しあわせ (shiawase) is the most common and colloquial reading. It expresses personal, emotional happiness — the warmth of contentment in daily life. This is the word people reach for when saying "I am happy" in an intimate, heartfelt way.
- 幸せ (shiawase) — happiness, being happy. Used as both a noun and a な-adjective.
- 幸せそう (shiawase sō) — looks happy, seems happy.
さいわい (saiwai) carries the meaning of luck, good fortune, or fortunately. It often opens a sentence to mean "luckily" or "fortunately," and has a slightly more formal or literary feel than しあわせ.
- 幸い (saiwai) — fortunately, luckily; a blessing.
- 幸いにも (saiwai ni mo) — fortunately, by good luck.
さち (sachi) is a poetic, classical reading meaning happiness or the bounty of nature — the gifts of the sea or mountains, for instance. It is common in personal names, especially women's names like 幸子.

Memory Tip
Think about the origin of 幸: a person once bound in handcuffs — the ancient meaning of this character — who was then set free. That moment of release, of narrowly escaping a grim fate, captures the purest sense of feeling lucky. The 8 strokes can be pictured as the bound and then unbound hands of someone just released. True happiness often comes from recognizing how fortunate you are to have what you have.
