Common Japanese Adjectives: 50 i-Adjectives and na-Adjectives to Know
50 common Japanese adjectives, both i-adjectives and na-adjectives, with readings and meanings — the descriptive words behind almost every sentence.
Adjectives are where description happens — size, distance, feeling, quality. Japanese splits them into two grammatical types, i-adjectives and na-adjectives, which conjugate differently (see i-adjectives vs. na-adjectives if you need the grammar). Here are 50 common ones, marked by type.
Size and distance (i-adjectives)
| Word | Reading | Meaning |
|---|---|---|
| 大きい | おおきい | big |
| 小さい | ちいさい | small |
| 長い | ながい | long |
| 短い | みじかい | short |
| 遠い | とおい | far |
| 近い | ちかい | near |
| 広い | ひろい | wide, spacious |
| 狭い | せまい | narrow, cramped |
| 高い | たかい | tall, high, expensive |
| 低い | ひくい | low, short (height) |
Weight, texture, and physical qualities (i-adjectives)
| Word | Reading | Meaning |
|---|---|---|
| 重い | おもい | heavy |
| 軽い | かるい | light (weight) |
| 強い | つよい | strong |
| 弱い | よわい | weak |
| 硬い | かたい | hard, firm |
| 柔らかい | やわらかい | soft |
| 明るい | あかるい | bright |
| 暗い | くらい | dark |
| 甘い | あまい | sweet |
| 辛い | からい | spicy |
Two traps worth flagging: 辛い is からい (spicy) above, but the same kanji read つらい means "tough, hard to bear" — only context tells you which. And 易しい (easy) and 優しい (kind) are both やさしい, separated only by the kanji.
Feelings and states (i-adjectives)
| Word | Reading | Meaning |
|---|---|---|
| 嬉しい | うれしい | happy, glad |
| 悲しい | かなしい | sad |
| 怖い | こわい | scary |
| 眠い | ねむい | sleepy |
| 痛い | いたい | painful |
| 難しい | むずかしい | difficult |
| 易しい | やさしい | easy (task) |
| 優しい | やさしい | kind (person) |
| 忙しい | いそがしい | busy |
| 恥ずかしい | はずかしい | embarrassing, shy |
Qualities and values (na-adjectives)
| Word | Reading | Meaning |
|---|---|---|
| 静か | しずか | quiet |
| 賑やか | にぎやか | lively, bustling |
| 便利 | べんり | convenient |
| 不便 | ふべん | inconvenient |
| 有名 | ゆうめい | famous |
| 元気 | げんき | energetic, well |
| 大丈夫 | だいじょうぶ | fine, okay |
| 親切 | しんせつ | kind, considerate |
| 心配 | しんぱい | worried, anxious |
| 必要 | ひつよう | necessary |
Manner and approach (na-adjectives)
| Word | Reading | Meaning |
|---|---|---|
| 簡単 | かんたん | easy, simple |
| 複雑 | ふくざつ | complicated |
| 大切 | たいせつ | important |
| 特別 | とくべつ | special |
| 熱心 | ねっしん | enthusiastic, eager |
| 丁寧 | ていねい | polite, careful |
| 上手 | じょうず | skillful, good at |
| 下手 | へた | unskillful, bad at |
| 自由 | じゆう | free (as in freedom) |
| 安全 | あんぜん | safe |
Remember the split, not just the words
The i/na distinction isn't a labeling formality — it changes how each word conjugates for past tense, negation, and connecting to a noun (i-adjectives inflect on their own; na-adjectives borrow だ/な the way nouns do). Learning a word's type alongside its meaning from the start avoids relearning it later. The full grammar rundown covers the conjugation patterns for both.
As with any list, these adjectives stick best learned in a real sentence rather than as a bare pair — 大丈夫 makes far more sense once you've seen it used to decline something politely than as a flashcard translation. Pair each word with an example sentence and audio, and review on a spaced schedule; see spaced repetition for Japanese.
