Japan's June numbers are out and the lead has widened in the Japanese console wars. The Nintendo Wii outsold Sony's Playstation 3 by a 6:1 margin, with 270,974 Nintendo consoles sold versus 41,628 Playstation 3 consoles. Microsoft's Xbox 360, which has been out longer and not performed well in Japan, sold 17,616 units in June.

The latest numbers suggest that Nintendo's lead is widening. Wii outsold PS3 just four to one in April and five to one in May, according to Enterbrain.

Enterbrain Inc., the publisher, found that Wii also outsold Microsoft Corp.'s Xbox 360 in Japan in June.

Nintendo, the maker of "Pokemon" and "Super Mario" games, sold 270,974 Wii consoles in Japan in June, while Sony sold 41,628 PS3 machines, and Microsoft sold 17,616 Xbox 360 consoles, it said. Overseas sales were not available.
