Translation guide
The English word 'noticing' refers to becoming aware of something, often through observation. In Japanese, expressing this concept depends on whether the noticing is visual, auditory, or a realization. Common verbs include 気づく (to notice/realize), 見かける (to happen to see), and 目に入る (to catch one's eye).
To express that you have become aware of something, often unexpectedly or after not having noticed it before.
The most common and versatile verb for 'noticing' or 'realizing' something. It can be used for both physical perception and mental realization.

If you notice any mistakes, please let me know immediately.
Synonymous with 気づく, but slightly more colloquial. Often used in spoken Japanese.

To express that you saw something by chance, often in a crowd or while out and about.
Used when you happen to see someone or something, often unexpectedly. It implies a casual sighting.

Literally 'to enter one's eyes', meaning something catches your attention visually. Often used for things that stand out.
Similar to 目に入る, but often implies something is conspicuous or stands out, sometimes negatively.
To express that you perceived something through hearing or smell.
To express that you have observed a change in something or someone.
気づく is for becoming aware of something (realization or perception), while 見かける is specifically for happening to see someone or something. Use 気づく for abstract realizations (e.g., noticing a mistake) and 見かける for visual sightings.
Avoid directly translating 'notice' as ノーティスする, which is not natural Japanese. Use 気づく or other context-appropriate expressions instead.
