A Misunderstanding / Mistaken Assumption

An incorrect assumption or misunderstanding resulting from a lapse in perception or intuition.

Good to know

勘違い（かんちがい） means a misunderstanding or mistaken assumption. You thought something was true, but your impression was wrong.

Use it for getting the wrong idea about a situation, a person’s feelings, a schedule, or what someone meant. It often points to an internal mix-up, not just an objective error.

勘違いする（かんちがいする） means to misunderstand or to get the wrong idea. Common forms include 勘違いしていた（かんちがいしていた）, “I had misunderstood,” and 勘違いだった（かんちがいだった）, “it was a misunderstanding.”

Do not confuse it with 間違い（まちがい）. 間違い is a general mistake, such as a wrong answer, typo, or factual error. 勘違い is more about a wrong impression or misreading the situation.

Example

それは私の勘違いでした。すみません。

That was my misunderstanding. I'm sorry.
