Apparently, due to time constraints and cultural differences, the hostess clubs have been removed from the experience. Hostess clubs are somewhat a Japanese tradition, in which males essentially pay for female company. Sure it sounds seedy to a Westerner, but much of the Yakuza charm comes from exploring a different culture.
"The content between Yakuza 3 US/UK and Yakuza JP is a little different in that we took out certain bits in order to bring the game to the west in the time alloted for us to do so. The parts we ended up taking out were parts that we felt wouldn't make sense (like a Japanese history quiz game) or wouldn't resonate as much (such as the concept of a hostess club)," SEGA told IGN. "We didn't replace the parts we took out, but we made absolutely sure that the story continuity stayed intact so that the story experience was the same as the Japanese version and that it didn't take away the human drama so inherent to the Yakuza series."</blockquote>
It's a shame that the content got cut, but we suppose the good news is that everything else in the game has remained in tact. Karaoke here we come.
