SM Entertainment's EXO-K & EXO-M who debuted a little over a week ago have already topped the record store charts in Japan without any promotions.

According to the April 15th Daily Chart of Tower Records, EXO-K & EXO-M's first mini-albums have already seized the #1 and #2 spots respectively.

The more astonishing fact is that EXO's albums have not been officially released in Japan, and the boys topped the charts with only the numbers from their Korean import album sales.

K-Pop is already the craze in Japan, and EXO is expected to become major stars in Japan in the near future.

EXO is a 12-member boy group, and the group promoting in Korea is called EXO-K, while the team promoting in China is being called EXO-M.

All 6 members of EXO-K are Korean, while 2 members of EXO-M are Korean and 4 are Chinese.

Both teams debuted with the same track "MAMA", written in Korean and Mandarin Chinese respectively.

Though it's only been a week since, the boys are being acknowledged for their live performances, refined talent, and good looks. Some believe they are the best rookies to debut this year.
