The Three Writing Systems of Japanese: Kanji, Hiragana, Katakana

How Japanese Writing Works: Three Scripts, One Language

Modern Japanese uses a unique mix of logographic and syllabic scripts—simultaneously.

1. Kanji (漢字) – Meaning-Based Characters from Chinese

• ~2,136 Jōyō (daily use) kanji taught in schools; ~3,000+ in literature.
• Each represents a morpheme (word/root): 山 = mountain, 食 = eat, 生 = life/birth.
• Multiple readings: on'yomi (Sino-Japanese) + kun'yomi (native Japanese). E.g., 山 = san / yama.
• Used for: nouns, verb/adjective stems, names, compound words.

2. Hiragana (ひらがな) – Curvy Phonetic Syllabary (46 base chars)

• Each = 1 mora (syllable-like unit): あ(a), い(i), う(u), え(e), お(o), か(ka)…
• Uses: grammatical particles (は wa, が ga, を o), verb/adjective endings (食べる taberu), words without kanji, children's books, furigana (reading aid).
• Flowing, cursive style.

3. Katakana (カタカナ) – Angular Phonetic Syllabary (46 base chars)

• Same sounds as hiragana, distinct shapes: ア(a), イ(i), ウ(u), エ(e), オ(o), カ(ka)…
• Uses: loanwords (コーヒー kōhī = coffee), onomatopoeia (ドキドキ dokidoki = heartbeat), scientific names, emphasis, robot/alien speech in manga.
• Sharp, blocky style.

Extras

• Arabic numerals (1, 2, 3) + kanji numbers (一, 二, 三).
• Punctuation: 、 。 「 」 ・
• Romaji (Latin alphabet) for acronyms, input, learners.

Mastery means fluidly switching among all three—like reading a sentence where nouns are icons, grammar is cursive, and foreign words are block letters.
