User blog comment:Tigerman1/Is Masamune from Amerika or from Japan?/@comment-2124020-20120407205552

He's from the United States, and in one of the episodes (I forgot if it was Masters or Fury) he says that he learned Japanese and headed to JApan to find Ginga. I'm pretty sure in the Zeo episode where Gan Gan Galaxy first come to America, Masamune talks about how New York (he doesn't say NY but it's pretty obvious from the dialogue) is his home but he can't give a tour till he finds Toby.
