Japanese retailers have preordered more than 700,000 copies of Super Mario Galaxy. Keep in mind, this is retailer preorders, we don’t know how many people in Japan have preordered. In the US, at last check there were 400,000 customer preorders.

Looks like the Mario mania is hitting Japan as well as the US!  Hopefully it can boost the sales of the Wii even more through the holiday season.
