Having lived and worked in Japan (Tokyo) for 9 years I can also attest to the truth of these statements. OTOH, if you don't have the time to do the "pre" work of going to those sites and lining up some locals, Asian Mystique and Clubboo are both high quality and dependable places to order from for take-out. I was just in Tokyo last week for only one night and tried Lisa from Asian Mystique, and just as in my previous tries, she was exactly the girl in the pictures on the website, and was also exactly as advertised. We had a true GFE, and even though only an hour she let me pop twice. It was truly great, as usual. The damages were 28,000 yen, which is not cheap, but then again as I said, for a quicky without preparation time these two services can't be beat.
Good hunting,
