@coolboymew @JoYo @igeljaeger @moonman @rin @tmy Yeah. As my friend explained: "They don't like foreign guy, because big body, and maybe make trouble." He said some let foreigners in, and further explained that you can pay to have her dress up like a Power Ranger and kick your ass. At that last line, he started snickering and then cackled. (He was a fun guy.)
If you just wanna get laid, though, this DJ from Tokyo FM explained to me that Roppongi is where you go to find "gaijin hunters". (I did not verify this, either, though obviously I made a mental note of it.)
