Japanese for When You Forgot Which Coin Locker You Used
Learn polite Japanese to say you forgot your locker number, describe your belongings, and ask staff to check for you.
By SofiaGetting around · Yapr Learn
You return to a wall of identical coin lockers and realize you have no idea which one is yours. This lesson gives you the exact Japanese to explain that you forgot the number, describe what you stored and when, and politely ask a staff member to check. You will learn どのロッカーか忘れました, 鍵, 番号, 係の人, and 探しています, plus the patterns 〜を忘れてしまいました and 〜を探しています. The register is polite but slightly flustered, so you can sound natural without being rude.
By the end, you can…
- say I forgot which locker I used.
- describe my belongings and the time I stored them.
- ask a staff member to check for me.
Listen once. Try it slowly. Then say it without looking.
Checking available voices…
どのロッカーか忘れました。
I forgot which locker it was.
dono rokkā ka wasuremashita
Use when you cannot remember the locker number or location.
鍵をロッカーの中に置いてしまいました。
I accidentally left the key inside the locker.
kagi o rokkā no naka ni oite shimaimashita
Use when the key is locked inside, not with you.
番号を忘れてしまいました。
I forgot the number.
bangō o wasurete shimaimashita
Use for the locker number specifically; 〜てしまいました adds a regretful tone.
係の人を探しています。
I am looking for a staff member.
kakari no hito o sagashite imasu
Use when you need to find someone in charge.
確認してもらえますか。
Could you check for me?
kakunin shite moraemasu ka
Polite request for staff to verify your locker or belongings.

Make it make sense
Useful pattern
The pattern 〜を忘れてしまいました expresses that you forgot something and feel it was a mistake. For example, 番号を忘れてしまいました (I forgot the number) and どのロッカーか忘れてしまいました (I forgot which locker it was). The simpler 忘れました is also correct, but 忘れてしまいました sounds more natural when you are flustered. To say you are looking for something, use 〜を探しています: 係の人を探しています (I am looking for a staff member) or 鍵を探しています (I am looking for the key).
When to use it
Use these phrases when you are standing in front of a bank of identical lockers and cannot remember your number. First say どのロッカーか忘れました or 番号を忘れてしまいました. Then describe the area and time: 三時ごろ、この辺に預けました (I stored it around three o'clock, around here). If you need help, say 係の人を探しています and then 確認してもらえますか. Staff procedures vary by facility, so ask rather than assume what they can do.
Listen to each line, then take one part and reply out loud.
すみません、どのロッカーか忘れました。
Excuse me, I forgot which locker it was.sumimasen, dono rokkā ka wasuremashita番号は覚えていますか。
Do you remember the number?bangō wa oboete imasu kaいいえ、番号を忘れてしまいました。三時ごろ、この辺に預けました。
No, I forgot the number. I stored it around three o'clock, around here.iie, bangō o wasurete shimaimashita. sanji goro, kono hen ni azukemashita確認してもらえますか。係の人が調べます。
Could you check for me? A staff member will look into it.kakunin shite moraemasu ka. kakari no hito ga shirabemasuA little context goes a long way
In Japan, coin lockers are often managed by a facility or station staff. Politeness matters: use すみません to open, and 〜てもらえますか to ask for help. Staff may ask for identification or details, but procedures vary, so do not assume a fixed policy. Avoid touching other lockers while staff assist you.
One thing to watch for
Using どのロッカーを忘れました instead of どのロッカーか忘れました.
Try this instead: The correct pattern is どのロッカーか忘れました, where か marks the embedded question. を would mark a direct object, which does not fit here. Say どのロッカーか忘れました。
Your turn
Try answering out loud before checking a possible answer.
1How do you say 'I forgot the number' with a regretful tone?
Show a sample answer
番号を忘れてしまいました。
This uses 〜てしまいました to show the forgetting was unintended. 番号を忘れました is also correct but less expressive.
2You need to find a staff member. What do you say?
Show a sample answer
係の人を探しています。
This means 'I am looking for a staff member.' You could also say 係の人はどこですか, but 探しています fits the situation of actively searching.
3Ask staff to check for you politely.
Show a sample answer
確認してもらえますか。
This is a polite request using 〜てもらえますか. 確認してください is also correct but more direct; 確認してもらえますか sounds softer.
When you forget your locker, say どのロッカーか忘れました or 番号を忘れてしまいました, describe the time and area, then ask 係の人を探しています and 確認してもらえますか.
