Mii makers in Japan and North America have been busy.
In a games seminar held in Japan on December 4, 2009, Nintendo president Satoru Iwata confirmed that over 100 million Miis have been created since the Wii launched in Japan and North America.
20 million Miis have been made in Japan, while players in North America have created 80 million. These numbers don't include Australia, Europe, or South Korea, or the Miis created over the Holiday season that saw over 3.8 million Wii consoles sold in the U.S. alone.
