The PSP is pretty hot right now in Japan. The Sony handheld is now spending its second week as the alpha platform in Japan's hardware sales charts. Not only that, but it's also its second week to sell nearly as much as the rest of the platforms did combined.

Its success has been attributed to the release of Capcom's Monster Hunter Portable 2nd G, which topped Japan's software charts the previous week. It's no coincidence then that the game is still on top of the software charts.

All the platforms have performed just as well as they did the previous week. Here are the hardware sales numbers in Japan for the week of April 6:

• PSP: 120,964
• DS Lite: 55,190
• Wii: 44,618
• PS3: 11,303
• PS2: 10,423
• Xbox 360: 1,452
