T-ara′s upcoming first Japanese album, Jewelry Box is set to be released on June 6.

The album is already showing huge potentials, as both the albums′ versions reached first and third place on Japan′s Tower Records.

A Tower Records representative said, "T-ara′s first album is showing explosive reaction in the daily chart′s first place position and is likely to sell 300,000 to 400,000 copies."

T-ara′s Core Contents Media Japan representative then said, "If the first album sells 500,000 copies, we will hold free guerilla concerts in both Korea and Japan."

Jewelry Box will include T-ara′s Bo Peep Bo Peep, Yayaya, Roly Poly, Lovey Dovey and more.
