Big in Japan

(Background: "Him" is a man for whom I have two datapoints, both of which involve his love of Japan. At his suggestion, we went to a dumpling store together.)

Me: So, what is it about Japan that appeals to you?

Him: (dramatic sigh) You know...I don't really want to be That Guy. That Japan Guy. Who is all into Japan, you know? That's really not interesting. I don't want to talk about it.

Crickets: Chirp!
