JLPT N5

～たことがある

Have done ~ before, experienced ~

Structure

Verb plain past (た-form) + ことがある

Used to state that one has previously had the experience of performing an action. It emphasizes prior experience rather than a recent event.

日本に行ったことがあります。

I have been to Japan before.

Using the plain present form (e.g., 行くことがある) instead of the plain past (行ったことがある).

Think of it as 'the experience of having done X exists'.
