How to say "irritated" in Japanese

• 歯がゆいはがゆいCommon
  i-adjectiveCovers the impatient, frustrated sense of 'irritated': the feeling when progress is slow or you can only watch. Typical when a colleague fumbles through a task you cannot do for them.
• もどかしい
  i-adjectiveVery close to 歯がゆい: vexing frustration at being held up or unable to get something moving. Use it when delays or someone's slowness leave you restless with impatience.
• むしゃくしゃ
  adverb (with と), suru verbA mimetic word for a vague, restless irritation — the grumpy, ill-humoured mood that builds after a stressful day, often without one clear target. It describes the mood itself rather than impatience at slow progress.
  怒おこりっぽい人ひとは１０まで数かぞえるようにすべきだ。そうすれば油あぶらが風波かざなみをしずめるように、むしゃくしゃした気持きもちはおさまる。↗

  A man who angers easily should learn to count to ten - it calms trouble like pouring oil on troubled waters.
• いがらっぽい
  i-adjectiveHere 'irritated' is the physical sense: a rough, scratchy feeling in the throat, not an emotion. For feeling irritated at someone or something, this is seldom the word you want.
  喉のどがいがらっぽい感かんじがします。↗

  My throat feels dry and raw and scratchy.
• 苛立たしげいらだたしげ
  na-adjectiveDescribes how someone looks — antsy, agitated, visibly irritated — rather than the feeling itself, so it suits descriptions of another person's manner. A less common word, and not for simply saying you feel irritated.

Use 「歯がゆい」 or 「もどかしい」 for frustration at slow progress or delays, 「むしゃくしゃ」 for a vague grumpy mood, 「苛立たしげ」 for someone's irritated appearance, and 「いがらっぽい」 only for a physically irritated throat.
