Yeah! Go take pictures, get some interviews, ask them what they think about the game, why they like it and why they are playing it (when it’s not a popular FG in Japan). Ask them who they think the top/bottom 5 characters are. Ask them what they think the game’s future is in Japan (will the PC version help them get more players to try it? will they continue to play the game after SF5 or other anticipated fighting games get released?)
Basically, I’d read/look at anything you write about the Japanese players, their history, their scene, and their thoughts on the game. That’s really interesting stuff to me.
