With the exception of the newly released Pokémon Fushigi no Dungeon: Sora no Tankentai, it was a relatively slow week of video game buying in Japan, with low sales of new software.
Even though it topped this week's chart, the latest Pokémon spin-off title didn't sell on par with its predecessors (two games that eventually came to the West as Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness), selling just 142,000 copies. In comparison to the combined 569,000 that previous Pokémon Fushigi no Dungeon games moved in their first week in Japan, that's rather meager.
Another weak performer rounded out the top ten, with Hudsons' Deca Sporta 2 moving just 9,000 copies. When the original was released in Japan, it sold 65,000 copies in its debut week.
