Via tokyohive:

The Recording Industry Association of Japan (or 'RIAJ') has just released their hard copy sales certifications for the month of December 2011. �It should come as no surprise that albums from some of today's most popular K-pop stars received certifications. CDs & DVDs from�Girls' Generation, KARA, Super Junior, 2PM, and Shinee obtained certifications last month.

This certification is based off the total numbers of CDs and DVDs sold to retailers.

RIAJ hands out these awards based on the following standards:

Gold - 100,000 units sold
Platinum - 250,000 units sold; Double Platinum - 500,000 units sold; Triple Platinum - 750,000 units sold
Million - 1,000,000 units sold; 2 Million - 2,000,000 units sold; 3 Million - 3,000,000 units sold
