According to the latest Famitsu data (via Kotaku), the Japanese video game industry increased slightly during the financial year ended March 31, 2008 and Nintendo clearly led the way. The landscape was completely dominated by the DS, Wii and software for those systems like Wii Fit and Mario Party DS.

Here's how the top five hardware and software charts shake out:

Nintendo DS: 6,343,547 units sold in 2007 (22,169,761 cumulative)
