Japanese perp names from their passports

Ok, here are the names and the pics of the Japanese perp passport from the recent trip. There were bunch of Japanese men showed up in the bus and made the nearby seats filled with Japanese speakers. I bet they are working for the economic hitman for Japanese government. Other wise, why there were so many Japanese - only men - traveling? What is their relationship to the Japanese Public Safety or Mafia?

Names are:
Asami Keisaburo
Nozu Hiroshi
Ichikawa Norihiro
