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.
