Canadian medical doctor transitioning to Japan?

This is a hypothetical. Given that a person has a Canadian MD, and they want to transition to Japan, what options are there?

Ive been looking online for a while and I cant seem to find much information on this. Are there any higher paying roles for someone with an MD in Canada (although I understand the pay is significantly less)

THIS IS A HYPOTHETICAL, BUT I REALLY WOULD APPRECIATE SERIOUS ANSWERS! Thank you!
