US citizen here, have been actively preparing for a permanent move to Japan with my Japanese citizen spouse, dual citizenship toddler, and our dog for the past 6 months. We are fortunate enough to have the money and legal pathway to do it, and it has still been one of the most stressful experiences (if not the most) of my life.

We’ve had to:

Sell our house, Sell our two cars, Get rid of all our belongings (gave most of them away because it’s just too time consuming to try and sell everything), Apply for a certificate of eligibility for my visa Apply for my visa, Get all the vaccinations and paperwork for our dog and wait 6 months after getting them done, Make arrangements for the dog’s overseas travel, Buy our airline tickets, Find an apartment in Japan without being able to see it in person, Find work in Japan, Find a preschool for our kid in Japan, Have to enter Japan within 3 months of my visa being issued (but NOT sooner than 180 days after the dog gets his 2nd rabies shot and bloodwork results), Etc.

And if we make a mistake on any one of those steps or get delayed and miss our 3-month window, we have to do half of the steps again.

All while continuing to work full time and with a move from our house to the apartment in the middle.

We are close to the finish line, but it has pushed us all to the absolute edges of our mental and physical limits. And again, we are extremely fortunate to have enough savings and equity in our home to even be able to try this…

For the average US citizen, I’d say it’s nearly impossible.
