With all my respect, good luck! Any effort pays off, sometimes in a mysterious way tho.
But...why Japan? I think some escorts in UK are happy to see you, or a short flight to Amsterdam would also do. In Japan, all those shops which accept "customers with handicaps" are asking you to book well in advance and you have to explain that you need a special assistance - in Japanese.
When you travel to Japan, I think it would be practical and safe to see one of the indies here - they speak English and they know where would be the best place (Love Hotel or your hotel) to play.
Still, you can be luckier as Japan's perception to people with special needs is changing - because of this guy. He is also known as an avid deri-heru user.
