Oh yeah, the ball lists for about $450 on their website. 46000yen.
Guess you could buy one ($450), have it shipped here (probably close to another $100 at least), and have one.
Coincidentally, if they can sell them over there for the equivalent of $450, I now understand why the Asian market seems to get so many new pieces. Why sell it here for $200, when you can ship them en masse across the pond, and get $450 for the same ball?
