What style of coat is this?

Picked it up at a vintage store for $10 CAD 3 months ago (no I will not shut up about this, why do you ask).

If you can't tell from the pics, it's single-breasted and the weird fabric patch thing is not symmetrical, and looks like it was designed that way. No belt at the back. I would think it would be an Ulster coat but the weird long lapels and that fabric patch thing don't seem to be characteristic of that?

Made in Korea, if that matters. Also, if anyone can read Korean/has any idea about its provenance in general, I'd be interested (yeah yeah I could just google lens it up but there's no joy in that). Other than the tags attached, I have 0 information
