The sky is blue, therefore the PSP is top in Japan

Just as the Xbox 360 is firmly planted at the bottom of the Japanese sales chart, the PSP is once again on top. The nitty-gritty numbers are presented to you below:

Week of June 30th-July 6th:

• PSP - 56,439 (2422)
• Nintendo DS - 47,455 (1,429)
• Wii - 44,525 (3,955)
• PlayStation 3 - 14,359 (3,614)
• PlayStation 2 - 11,768 (4,095)
• Xbox 360 - 4,776 (328)
  

Seems like video game hardware sales are down in general over in Japan this week. All the current-gen systems reported lower than last week sales. But hey, our favorite portable is still at the top, besting the runner-up, the Nintendo DS, by 8,984 units.
