Thanks for your input. I never doubted that it was a good place to be. But here's the kicker: I applied to SAIS and choose the 'Japan Studies' concentration. At the Bologna Center, it seems you can take classes dealing with geographic location in the world except East Asia. I felt like an idiot after sending in my application; I was confident I wouldn't be accepted. Surprise surprise!
Anyway, I'm really taking a good, hard look at the SAIS curriculum now. I'd ultimately like to go a bit further than Japan Studies and go for the International Relations of Asia specialization. I guess I could get the degree's core requirements and international economic requirements out of the way at Bologna and focus on the Asia/IR stuff back in DC.
