Sorry Kurosaki, I don't know too many academies in Asia. I tried looking some up for you, but I couldn't find much. All I could find was an article mentioning The Tennis Academy of Asia. The link is here:
I couldn't find their website or number though, but it was just opened in June 2004, so it may take some time for them to get a website. Hope this helps.
And to jrb, there are lots of reasons to go to Asia. You're probably one of those ignorant people who think that everyone in Asia lives in huts.
