Translation guide
In Japanese, expressing 'new discovery' depends on context. For scientific or factual discoveries, use 発見 (hakken). For personal realizations or emotional discoveries, use 気づき (kizuki) or the verb 気づく (kizuku). In casual speech, わかった (wakatta) or 知らなかった (shiranakatta) often convey the sense of a new realization.
Referring to finding something previously unknown, such as a scientific breakthrough, a new species, or a hidden object.
The standard noun for 'discovery' in objective, factual contexts. Can be used with する to mean 'discover'.
The discovery of a new star was announced.
He discovered a new species of frog.
Emphasizes that the discovery is new. Often used in headlines or titles.
Expressing a sudden understanding, a new awareness about oneself or life, or an 'aha' moment.
A noun meaning 'realization' or 'awareness'. Often used in self-help or reflective contexts.

Verb meaning 'to notice', 'to realize', or 'to become aware'. Commonly used for personal discoveries.
Casual way to express 'I got it' or 'I understand now', often used when a new piece of information clicks.
Oh, I get it now! So that's what it was.
Literally 'I didn't know', used to express that something is new information to the speaker.
What, really? I had no idea!
Focusing on the action of discovering rather than the result.
発見 is for objective, external discoveries (e.g., scientific findings, lost items). 気づき is for subjective, internal realizations (e.g., understanding feelings, noticing a mistake). Using 発見 for a personal insight sounds unnatural.
Discovered a new planet.
Realized my own shortcomings.
The phrase '新しい発見' (atarashii hakken) is grammatically correct but often redundant because 発見 already implies newness. Use 新発見 for emphasis in formal writing, or simply 発見.
A new archaeological discovery was reported.
自分の間違いに気づいた。
I realized my mistake.
I finally realized her feelings.
いいレストランを見つけた。
I found a good restaurant.
