not contrained I would believe. Japan is Nintendo 1st priority, it is their homeland they will meet demand there first.
I would assume it is not "hard" to find, but it is hit or miss. You might need to hit up 3 stores to get a Wii, but unlike NA you will find one if you want one.
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
