How to use it
Talking about an experience one has had at some point in life.
- This pattern talks about an EXPERIENCE accumulated over one's life, not a specific past event. This is the key extension compared to N5: distinguishing "have done (before)" from "did."
- Key rule: this pattern is NOT used for an event with a specific, fixed time. 去年、日本へ行ったことがあります is WRONG — because 去年 (a specific point in time) is stated, you must say it directly with 去年、日本へ行きました. An experience is something "somewhere in one's life," not tied to a fixed date.
- As a result, it's also not used for something that just happened or a daily routine. 今朝ご飯を食べたことがあります sounds very strange — eating breakfast is not a "life experience."
- The negative form is very useful in conversation: まだ食べたことがありません (I have never eaten it yet). Add 一度も to emphasize: 一度も行ったことがありません (not even once).
Examples
日本の温泉に入ったことがありますか。
Have you ever been in a Japanese hot spring?
私はまだ富士山に登ったことがありません。
I have never climbed Mount Fuji yet.
この歌は何度も聞いたことがあります。
I have heard this song many times.
Keep in mind
- Adverbs commonly used with it: 一度, 二度, 何度も, まだ, 一度も.
- Compare with N4-091: ～ることがある (dictionary form) = occasionally; ～たことがある (ta form) = have done before. Learn these two patterns together.
Common mistakes
-
Wrong去年、日本へ行ったことがあります。
Last year I went to Japan.
Correct去年、日本へ行きました。
A specific time (去年) has been stated, so this is a past event, not a general experience → use the ました form.
-
Wrong今朝、パンを食べたことがあります。
This morning I ate bread.
Correct今朝、パンを食べました。
A recent everyday occurrence isn't a "life experience" — state it directly with the ました form.
Exam tips
- N4 trap: a sentence with 去年／先週／昨日 + ～たことがあります → definitely WRONG. If there's a specific time marker, this pattern can't be used.
