Make it make sense
Useful pattern
The pattern '〜てもいいですか' (temo ii desu ka) is used to ask for permission. For example, '留め金を開けてもいいですか' means 'May I open the latch?' You can replace the verb with other actions: '触ってもいいですか' (sawattemo ii desu ka) means 'May I touch it?' This pattern is polite and commonly used in stores.
When to use it
Use these phrases when you are considering purchasing a used instrument case. It's important to ask before handling merchandise. For example, after spotting a case you like, you can say 'すみません、留め金を開けてもいいですか' (Sumimasen, tomegane o aketemo ii desu ka) to get the staff's attention and ask permission. If they agree, you can then test the latch and ask 'ちゃんと閉まりますか' to confirm it works.
Listen to each line, then take one part and reply out loud.
すみません、この楽器ケースの留め金を開けてもいいですか。
Excuse me, may I open the latch of this instrument case?Sumimasen, kono gakki kēsu no tomegane o aketemo ii desu ka.はい、どうぞ。
Yes, go ahead.Hai, dōzo.ありがとうございます。ちゃんと閉まりますか。
Thank you. Does it close properly?Arigatō gozaimasu. Chanto shimarimasu ka.はい、閉まりますよ。
Yes, it closes properly.Hai, shimarimasu yo.A little context goes a long way
In Japan, it's customary to ask permission before handling items in a store, especially for delicate items like instrument cases. Using polite language such as '〜てもいいですか' shows respect. Staff are generally helpful and may assist you in testing the latch. Avoid opening cases without asking, as it may be considered rude.
One thing to watch for
Using '開けてもいい' without 'ですか' to ask permission, which can sound abrupt.
Try this instead: Always add 'ですか' to form a polite question: '留め金を開けてもいいですか。' This makes the request polite and appropriate for interacting with staff.
Your turn
Try answering out loud before checking a possible answer.
