There's been a fair share of doom and gloom around Vita recently, with one consistent source of bad news coming from the Japanese charts. Thankfully, this week represents a reverse in the trend, with Sony doing well in the software chart and seeing a revival for its handheld in the hardware stakes.

In the software chart, the top 10 has a total of six titles for Sony systems, including three on PS3 and two on PSP. The Vita entry, SEGA's rhythm title Hatsune Miku Project Diva F has surged to number one, with impressive sales of 158,009.

[PSV] 01. Hatsune Miku Project Diva F (Sega, 08.30.2012): 158,009 (NEW)
[3DS] 02. Devil Summoner Soul Hackers (Atlus, 08.30.2012): 73,690 (NEW)
[3DS] 03. Senran Kagura Burst (MAQL, 08.30.2012): 70,569 (NEW)
[3DS] 04. New Super Mario Bros. 2 (Nintendo, 07.28.2012): 55,028 (1,068,878)
[PS3] 05. Neptune V (Compile Hearts, 08.30.2012): 35,670 (NEW)
[PSP] 06. Gundam Age (Namco Bandai, 08.30.2012): 32,782 (NEW)
[PS3] 07. Aqua Pazza (Aqua Plus, 08.30.2012): 28,806 (NEW)
[PS3] 08. Sengoku Basara HD Collection (Capcom, 08.30.2012): 27,551 (NEW)
[NDS] 09. Pokemon Black & White 2 (Pokemon, 06.23.2012): 27,198 (2,692,626)
[PSP] 10. Rurouni Kenshin (Namco Bandai, 08.30.2012): 16,610 (NEW)

That new release has had a positive impact for Vita in the hardware chart, with Sony's system coming in second place with a major jump in sales. If you separate sales of 3DS and 3DS XL, Vita would actually be top of the chart, and the significant increase is shown by last week's figures in parenthesis.

Nintendo 3DS: 67,926 (64,921)
PlayStation Vita: 46,877 (9,751)
PlayStation 3: 12,846 (12,243)
PlayStation Portable: 10,918 (10,676)
Wii: 8,038 (8,476)
Xbox 360: 525 (563)
PlayStation 2: 411 (439)
Nintendo DSi: 279 (311)

While it's still not quite hitting the heights some may expect, the principle of "games sell systems" has definitely worked in Vita's favour in Japan this week, though Hatsune Miku Project Diva F is unlikely to be the answer in Western markets.
