You could probably guess the two best-selling games in Japan this year: Pokemon Black and White and Monster Hunter Portable 3rd. The DS monster collecting adventure and the PSP monster murder adventure sold 4,734,064 and 3,163,750 units respectively, according to a year-end report by ASCII. Monster Hunter managed to finish in second place after less than one month of sales -- it was released on December 1.

It should come as no surprise, given the blockbuster status of those two, that the DS and PSP were the best-selling hardware platforms in Japan as well. The PSP was the only console to show growth in sales versus 2009, selling 600,000 more consoles than the previous year. 2,719,544 DS systems were sold in 2010, down a million from 2009.
