The number single for the past week was “Oh!” by Shoujo Jidai (Girls’ Generation), selling a truly mediocre 66,253. I think this is the first time in the six months I’ve covered the Oricon rankings that the weekly #1 probably won’t break gold (100,000 copies sold).

SKE48‘s “Kisu Datte Hidarikiki” was at #2, with 36,501 sold for a two-week total of 547,973. That’s a 6.6% second week, demonstrating that SKE48 isn’t extending too far beyond its established fan base. Selling as much as they did in the first week, though, do they need to extend too far beyond that?

Hikawa Kiyoshi‘s “Saigo to Kimeta Onna Dakara” took #6, selling 12,234 in a strong second week for a total of 68,746.

Momoiro Clover‘s “Ikuze! Kaitou Shoujo” started off at #7 with 10,003 copies sold.

And somehow, Nogizaka46’s “Hashire! Bicycle” got another pop – back up to #8 with 9,844 in sales. Again, I’ve lost track of total sales for it because it dropped below #30 for a week, but it’s been persistently popping ever since. It was at #19 with 3,815 in sales last week, so it looks like, in contrast to SKE48, Nogizaka46 is going beyond its fan base.

AKB48 took #12 with “Gingham Check” now totaling 1,274,765 in sales.

“24karats TRIBE OF GOLD” from EXILE TRIBE was at #13, just one position behind last week’s showing, with a running total of 192,428.

Behind them was Bump of Chicken‘s “firefly,” which barely missed gold this week, hitting a total of 98,886.

KAT-TUN‘s “Fumetsu no Scrum” found itself at #20, bringing its total to 172,287.

Wrapping up the singles, Kanjani8’s “Aoppana” held in there at #28, with its total now 233,272.

In albums, Yamashita Tatsuro-san took the top position with his compilation album “Opus ~All Time Best 1975-2012~” selling 275,825 copies.

Superfly’s “Force” was at #2, with a very strong second week bringing it to 158,779 in sales.

Green Day‘s “Uno!” sold 36,145 copies at #3 and, if I’m not mistaken, are the first American group I’ve had the privilege of mentioning in these rankings.

“Queens are trumps” from Scandal sold 35,424 at #4.

Kobukuro‘s “All Singles Best 2” took #5, now with 599,926 copies sold.

Nishino Kana-san was at #8, with “Love Place” breaking platinum for a total of 266,847.

Finally, SKE48’s “Kono Hi no Chime no Wasurenai” stayed within the top 10 at #9, adding 14,856 for a grand total of 125,469.
