Yeah, Japan has different standards when it comes to pornography, etc. They also have issues with foreigners or Gaijin. I have studied Japanese culture for a number of years. I also took 2 years of Japanese in highschool.
Essentially, they are completely fascinated with American, Western culture, music, clothes, etc, but hate them with an equal amount of passion. However, when you visit you will be aforded all thier great hostipality, esspecially if you have money.
As for "getting laid" it is extremely hard, next to impossible, to hook up with a Japanese girl, unless you plan on getting married. However, incest and **** are extremely common-place there.
For example, a mother will sleep with her son in order for him to keep his mind on school works, and less on gettinga girlfriend.
It can be a bizzare place. I still want to go. My accupunturist (who is japanese) also wants me to go. Other than money, my only concern is thier hatred for US.
