NHK Let's Learn Japanese

There was also another Japanese language study series named NHK Japanese: how to survive in Japan?which was produced by the Japanese TV Network NHK in 1989. This 40-part series was about David Roberts (ostensibly an American but speaks with an Australian accent) who went to Japan for work. He was assisted by a beautiful girl named Yuko Goto, and in later episodes they are joined by David's wife, Cathy Roberts. David was going to introduce to Japan American culture and food with the American Train.
