I received a call from “immigration “… is it a scam?

I got a call from this number today +183343635763, which doesn't appear when I look for it on google.

There was a pre-recorded voice message saying that it was immigration and I they have been contacting several times (I used my phone's call translation, as my Japanese isn't good).

Then I pressed 1, as they offeres just two options (1 for Japanese, 2 for Chinese).

Then, a man picked up the phone, spoke to me in Japanese, then in Chinese, I asked what was that? (In Japanese) and he ended the call.

I am a resident here and I am neither Japanese or Chinese.

Is it… a scam? I am scared now because I replied and they might recorded my voice.

Does anyone has any insight about this??
