I was in  Akihabara only two weeks a go. There my mates and I met two guys while we ate dinner, they were otaku boys who came in from the Suburbs to buy anime figurines. We spoke about games and anime and shared a Santori Malt, I hope they are OK. I have traveled all over the world, you tend to do that in the Navy, and I have never met a kinder, more polite or respectful people than the Japanese.  
 
Best of luck to you.
