.:*・°☆ Arashi: Your Eyes Oricon Rankings
Here are the sales and ranking information for Your Eyes from Oricon.co.jp. Note that these numbers are mostly just estimates, around the end of the week the number may jump up (for the total), because some merchants only report to Oricon weekly, rather than daily.

Face Down's weekly sale was 526,106, although you'd get a lower number if you added up all the days. I highly doubt Your Eyes will surpass Face Down, but I hope it can hit at least 500,000!
