While Nintendo continues to top the sales charts in its home market, overall sales for game software and hardware were down 6.9% in Japan during 2009 to ¥542,640 million ($5.9 billion). In fact, the new sales data from Famitsu publisher Enterbrain, covering December 29, 2008 to December 27, 2009, shows that the Japanese video game market shrunk for the second year in a row.

The Japanese game market has not seen positive growth since 2007, when overall sales jumped 9.9% to ¥687,660 million thanks to the strong hardware sales of Nintendo's DS and Wii, as well as Sony's PSP.

Software sales for 2009 exhibited a mild decline, dropping 1.8% to ¥326,160 million ($3.5 billion). Games on Nintendo platforms dominated the software sales chart, taking all but a single slot in the top 5.
