Video game sales in Japan have been on a decline as of late, and Media Create sales from the week ending April 18 certainly don’t show a bright outlook for the future.

For the second week in a row, New Super Mario Bros. Wii holds the top spot despite a 14% drop in sales. In the runner-up spot was Friend Collection, which is starting to see a steady decrease in sales. Still, each game managed to sell 32,000 and 21,000 copies, respectively. Rounding out the top 10 was the latest Pokemon Ranger (16,000) and Wii Fit Plus (15,000).

Outside the top 10, former number-one hit Etrian Odyssey dips from 7 to 12, while the Ultimate Hits edition of Dragon Quest XI falls to a modest 20 from 18. Longtime favorites such as Wii Sports Resort, Mario Kart Wii, New Super Mario Bros.,The Legend of Zelda: Spirit Tracks, and Pokemon HeartGold/SoulSilver continue to linger throughout the top 30.

Next week should be a rather interesting battle for the top spot as both Metal Gear Solid: Peace Walker and Dragon Quest Monsters: Joker 2 are released. Both games should see debuts over 500k, easily making next week the biggest week of 2010.
