How to transport pet snake from Tokyo

Hi,
so I have a pet corn snake (nothing dangerous), I live in Tokyo but plan on going to school for about a year to the States so I want to ship him to Hungary for my brother to take care of.
Does anyone know of a reliable relocation company that can take care of that? (I don't speak Japanese btw)
As far as I know I can't take the snake with me in the cabin under any circumstances, though that would be ideal.
(Please don't say I should leave it here, that's not even a consideration)
Hope someone has an idea, thanks!

You might want to check with the Hungarian Embassy/Consulate about the import procedures into the destination country. (Excuse me if you already have.)

You are not flying once to Hungary and take the snake to your brother yourself, I assume?

Thanks, I've checked already. It's a pain in the butt but possible XD
If I could I'd prefer to fly there myself and have the snake in the cabin with me but that seems to be out of the question :( And I'm really really vary of just putting him in a cargo hold, I don't think most airlines have the necessary requirements nor do they care if the pet arrives alive. I've checked with JAL for example and they specifically make you sign a waiver in case your pet dies during transport.

Have you checked with one of the international pet transport companies? When you google that, several will come up, some also ship reptiles. I have no experience, so can't make any suggestions. With all the paperwork and stuff, it could be an expensive trip.
Good luck finding a solution!
