I think the reason is the high technology in Thailand. Recently, I saw TV program which many transgendered people talked about their lives. Most of them said Thailand is the greatest country to have the transgender operation because of its technology. The transgender technology in Thailand is really progressed comparing other countries. In fact, most of the people who have the transgender operation said they had the operation in Thailand.
Also, Thailand is known as the warm country. The Japanese are unfamiliar with transgendered people. On the other hand, people in Thailand are familiar with those people, so I think many transgendered people in Thailand.

I think transgendered people have the same civil rights as the other people. even if they are transgendered people, nothing is different with other people. They should not be discriminated. We should make the world that transgendered people can spend comfortable life and don't feel the difference between them and other people.
