一番

• Reading: いちばん
• Romaji: ichiban
• Kanji breakdown: 一 (ichi) — one; 番 (ban) — number, turn
• Pronunciation: /i.tɕi.baɴ/

Meaning

Number one; first; first place. As an adverb: most; best; -est.

Functions as both a noun (number one/first place) and a superlative adverb (most/best). Japanese does not have superlative adjective forms — 一番 before an adjective creates the superlative (一番高い = tallest/most expensive). Essential for making comparisons.

Examples

1. 日本で一番高い山は富士山です。 The tallest mountain in Japan is Mt. Fuji.
2. 果物の中でりんごが一番好きです。 Among fruits, I like apples the best.
3. 一番近い駅はどこですか。 Where is the nearest station?
