Hi. I’m a Brit just married my Japanese girlfriend in Tokyo. If you are thinking of doing the same crazy thing. Please note . Paperwork. Then more paperwork. And after that more paperwork 😂😂. You will still be wrong , but if you do your homework and get multiple opinions ( each one said something different) from officials. You will do ok. Am now happily married but have to return home to start the dreaded visa process 😂😂😂
