Any Clinics in Japan

Does anyone have any information about any clinics offering PGD in Japan? Preferably in Okinawa specifically. There is one clinic that offers IVF but I can not get enough information from their website. There is very little info in English. Traveling to Mainland Japan is affordable so any info about Tokyo is very helpful as well. I could travel to Hawaii but it is a bit more expensive when you include the cost of hotel accommodations. I might save more money in the long run traveling to California.
