Applying for Japan Visitor Visa from the UK as a visitor in the UK?

Hello,

So, I am a current international student in Canada and wanted to apply for a visit visa for Japan for Christmas. Issue is, I am going to be in the UK for the next two months and will be leaving in the next two weeks so I kind of need my passport for now. I also have a Pakistani passport so I would need a visa either way to visit Japan.

I was wondering, is it possible for me to apply for a Japanese visit visa from the UK as a visitor in the UK or does it have to be from a country of residence?

Also a side question, I am reading online that the waiting times aren’t that bad but is that still true considering everything just recently opened up after COVID? Any and all help would be appreciated.

Thanks!
