117 yen = 1 US dollar (at the moment)
117 x 11,000 = 1,287,000 yen
So I guess I should have figured my spending limit to be under $11,000.
Or alternatively, 1,200,000 divided by 117 = $10,256
How'd you guys figure $110,000?
Back on topic, I downloaded Boot Camp to my MBP. By default it downloaded the Japanese version, so looks like I didn't really have to worry.
