Despite what some people say, Nintendo's clearly still got plenty of fight in it yet, if this week's Media Create charts from Japan are anything to go by.

As reported by Gematsu, this week's Japanese chart sees 3DS title Hatsune Miku: Project Mirai 2 from Sega top the charts with 88,708 sales in its first week on sale, closely followed by the evergreen Pokémon X and Y, which sold 86,391 this week and recently passed three million lifetime sales.

After a bit of a gap, third place is occupied by Square Enix's Lightning Returns: Final Fantasy XIII, which has now sold 337,155 copies since its release on November 21.

Fourth place in the chart goes to Nintendo's Super Mario 3D World, which had a somewhat underwhelming first week but still managed to come in second place behind Lightning Returns. This week it sold 39,812 copies, which is a drop since last week's launch week figure of 99,588 but may have contributed to this week's good news for Nintendo: a significant, noticeable increase in Wii U sales.

This week, Wii U sales in Japan overtook the PlayStation Vita and original 3DS with 28,518 units, up from last week's figure of 21,002 and making it the week's second best-selling system. 3DS XL (or LL, as it's called in Japan) is still the leader of the pack by a considerable margin, however, selling 82,409 units in a week -- a significant increase even from last week's figure of 63,709. By comparison, Xbox 360 sold 309 units. Both the PlayStation 4 and Xbox One are yet to be released in Japan.

While the Wii U is still clearly in the shadow of its diminutive stablemate, the increase in sales is a positive sign for the troubled console on its home turf. It remains to be seen whether it will be able to continue this momentum and increase its sales week-on-week, however -- it's got until February to build up a decent lead on PlayStation 4.
