Kanji vs kana: when to write which

Practical choices for learners writing sentences, journals, and JLPT answers.

Japanese mixes three scripts on purpose. Knowing when to prefer kanji versus kana makes your writing readable and exam-safe. **Prefer kanji** for content words you already studied (nouns, verb stems, i-adjectives). It reduces ambiguity: はし could be bridge, chopsticks, or edge — 橋 / 箸 / 端 disambiguate. **Prefer kana** for particles (は, が, を), verb endings, and words normally taught in kana (ありがとう, きれい in many beginner texts). Over-kanji-ifying beginner prose looks unnatural. **JLPT tip:** Reading sections assume standard orthography. If you only recognise a word in hiragana, drill the kanji form with stroke order so recognition flips both ways. **Practice loop:** read a short sentence → convert with the furigana tool → rewrite it by hand with correct kanji from worksheets → check lookalikes if any character felt shaky. Kanji carries meaning density; kana carries grammar. Balance both and your notes start looking like real Japanese instead of a romanisation crib.
