There's one in Canberra, as well as Guam, Hawaii, and Bangalore. I don't know if they're Japanese per se; "joint" is probably better. The US territory ones are NOAA or NASA in collaboration with JAXA. http://www.insidegnss.com/auto/popupimage/QZSS%20ground%20segment_lo.jpg http://www.insidegnss.com/auto/popupimage/QZSS%20ground%20se... Dunno if those will help with the "centimeter resolution" bit, but it'll certainly augment GPS. The dwell over Australia and other non-Japan areas for the non-stationary sats will be shorter, but still will be useful while they are visible. And outside of "canyon" areas that will be quite often. The geostationary sats will be useful over quite a lot of the west Pacific and east Indian oceans.
