How to say "noisy" in Japanese

Choosing the right word
  • うるさいJLPT N5approx.Common
    i-adjectiveThe everyday word for a loud, irritating noise: 'the neighbors are noisy', 'this fan is noisy'. It is what most learners want for 'noisy', and it is also commonly used to tell someone to be quiet.
    隣となりの部屋へやがうるさいのです。↗
    It's noisy next door.
  • 騒がしいさわがしいJLPT N2approx.Common
    i-adjectiveCovers noisy in the sense of boisterous, bustling commotion—a lively crowd, a clamorous place. It describes an atmosphere of stirring noise rather than a single irritating sound, so it suits scenes and environments.
    よく騒さわがしい部屋へやで働はたらいたものだった。↗
    I used to work in a noisy room.
  • やかましいJLPT N2approx.Common
    i-adjectiveA forceful word for loud, clamorous noise, close in sense to うるさい but stronger and more gruff. It also has the sense of being fussy or demanding about details, which goes beyond 'noisy'.
    ジョーはやかましい隣人りんじんと口くちをきく間柄あいだがらではなかった。↗
    Joe was not on speaking terms with his noisy neighbor.
  • ウザイCommon
    i-adjectiveColloquial slang whose primary sense is annoying; 'noisy' is secondary, as in telling a pestering person to shut up. Rarely the word you want for describing literal noise; use うるさい instead.
    シンジってうざくねぇ?うぜーよね。↗
    Isn't Shinji a pain? He is, isn't he?
  • 騒然そうぜんCommon
    taru-adjective, adverb (with と)Describes a state of uproar or confused commotion—a room or situation turned noisy and unsettled, such as after startling news breaks. It is about the upheaval of a scene, not a loud sound you would casually mention.
    その部屋へやは騒然そうぜんとしていた。↗
    The room was in disorder.

「うるさい」 is the default for loud noise; 「騒がしい」 suggests boisterous commotion; 「やかましい」 is a forceful variant; 「ウザイ」 is colloquial and more 'annoying'; 騒然 describes uproarious confusion in scenes or situations.
