Is there any agency who could help me to come to Japan from Germany which doesn’t cost a lot. Problem is I need a lot of help and can not stand or go and my weight is high. So I do not know to be honest how I can go on Airplane in first place ^^ and is there a possiblity to get help in Japan and an Hotel with Hoist (Lift)? Thank you very much :)
Yes, it is hard, but possible to rent hoists here.
As for agencies, there are none from Japan who would be able to come get you that I am aware of. It would likely be best to take someone with you from Germany to Japan. Maybe search for “travel care partner” in German?
