After a brief one-week run on top of the Japanese charts, Metal Gear Solid 4: Guns of the Patriots has stepped down in favor of the PSP game, Super Robot Taisen Advance Portable. It's brief stay on top of the charts echoes the game's sales in Europe, where it also yielded after only a week on top.

New this week in the Japan charts in Mario Super Sluggers, otherwise known as Super Mario Stadium: Family Baseball in Japan. It's a surprisingly mediocre entry considering Japan's love for Mario games on the Wii. Here are the rest of the top games in Japan for the week ending on June 22.

1. Super Robot Taisen A Portable
2. Metal Gear Solid 4: Guns of the Patriots
3. Super Mario Stadium: Family Baseball
4. Harukanaru Toki no Naka de 4
5. Mario Kart Wii
6. Wii Fit
7. Monster Hunter Portable 2nd G
8. Jikkyou Powerful Pro Yakyuu Portable 3
9. DS Bimoji Training
10. Pro Yakyuu Team o Tsukurou!

On the hardware side of things, the PSP reigns on top once more, with a few hundred short of 60,000 units sold in Japan. The Wii, which ran second, sold little more than 41,000. Here are the hardware sales numbers in Japan for the same week:
