The English word "irritation" covers both physical discomfort and emotional annoyance. In Japanese, these are expressed with different words and patterns. This guide helps you choose the right expression based on whether you mean a physical sensation, a feeling of annoyance, or the act of provoking someone.

いらだち is a noun describing the state of irritation, while イライラ is a mimetic word that can be used as a noun or a verb (イライラする). イライラ is more colloquial and vividly expresses the feeling. In formal writing, いらだち or 苛立ち is preferred.
English 'irritation' is often used in phrases like 'I have an irritation on my skin.' In Japanese, you would typically specify the symptom (e.g., かゆみ for itch, かぶれ for rash) rather than using a generic word. Using 刺激 in such contexts may sound unnatural.
My irritation grows.
苛立ちを抑えられない。
I can't suppress my irritation.
