I had better experiences in Roppongi and out in Chiba. Roppongi girls were very expensive, but were all Japanese and very attractive. Most spoke english.
English speaking girls who are willing to get laid with foreigners can be found in Roppongi and Akasaka areas in Tokyo. They think that having a foreign boyfriend or getting laid with them is cool. It is possible for a foreigner to get laid in Japan.
There are many establishments such as English schools that allow foreigners to have little fun with the students and employees, just keep looking, they are out there. If you are as gifted as me, you might find some pussies very small. Some of the delicate flowers of the orient just can't take a full size penis. Also, Japanese condoms are not big enough for many foreigners, so you might want to bring your own.
