Tips for relocating reptiles to Japan

We're looking to move soon but we have a lot of pets. Cats are fairly easy to look up on the whole process but reptiles are pretty sparse for information.

I was wondering if anyone had any experience in relocating their snakes or geckos and had some tips they wish they knew before going through the whole process. Bonus if it was from America. At the moment we're looking to go with a relocating company so they can handle all the nuance through their experience.
