Has anyone gone through the process of transferring their Invisalign treatment from another country (specifically the US) to Japan?

I’ve had Invisalign for about 5 months as of now and when I first started I wasn’t aware that I was moving to Japan so soon- due to circumstances. I’m pretty sure my treatment is for about another 10 months so l’d have to find an orthodontist in Japan to transfer over to. I’ve tried finding clinics that take transfers but most of them say that I’d have to start all over with them,
which of course it’s much more expensive that way. I’ve paid monthly here in the US, and I’ve paid about half of my treatment already so I’d really hate to start all over
again and pay thousands more. I was wondering if anyone has gone through transferring to Japan or if there’s any clinics that take transfers? Or any advice in
general for my situation.

(Also, if anyone knows any good orthodontist near Yokohama please let me know)
