PS Vita sales saw a much needed boost in Japan last week, shooting up to 46,877 from only 9,751 the week before, reports Andriasang.

This boost is likely to be a direct result of Hatsune Miku Project Diva F which hit stores last week. The latest of SEGA's rhythm titles shifted an impressive 158,009 copies.

However, Vita still can't compete with the 3DS, which saw a small bump in sales to 67,926 units.
