You have to understand what it's like for Gaga. She got the "grand entrance", she was like the special guest, the only foreign one in a room filled with Japanese artists.
She must've automatically thought / assumed the talk-time would be centered on her. You could see this as arrogant, but I think it's quite natural.. She didn't understand anything anyone was saying, but everyone was constantly talking about her.. so when she was asked that question, she probably thought she'd do people a favor by explaining something about herself. And she did it in a quite a polite way, she smiled a lot (for Gaga's measures).
She was trying to represent herself for her Japanese fans. Stuff as much info as possible in the little time she got.
But Ayu was amazing as well. I think both ladies had a lovely talk, and that's it!
