Nintendo's Super Mario Galaxy 2 sold 340,000 copies during its first week on sale in Japan, reports Japanese sales tracker Media Create.

The first week total compares favourably to the first game in the Galaxy series - that sold 251,000 copies - but doesn't come close to matching the huge sales of New Super Mario Bros. Wii. The multiplayer side-scroller sold a massive 953,000 copies during its opening week.

Super Mario Galaxy 2 goes on sale in the UK on June 11, with those desperate to get their hands on the game invited to attend a midnight launch in London.
