The popular female group Jewelry has released the title song of its fourth album, `Superstar,` in Japan. The group has also chosen `Superstar` as the title of its fifth single to soon be released in Japan. The group`s agency is currently in talks with the Japanese record company Bing Music.

"We have decided to name Jewelry`s fifth single `Superstar.` The single will be released with Korean vocals in July. The group will re-record the song in May and pose for the single`s jacket pictures in early June with Japanese staff," said Jewelry`s agency on May 12. The agency also added that Jewelry will release its fourth full-length album in Japan concurrently with the new single, and in August produce a special album containing the group`s best songs since its debut.

The group decided to name its new single `Superstar` at the urgent request of Bing Music, which said the song `Superstar` had great potential to become popular in Japan thanks to the group`s impressive vocals, even though they are in Korean.

Jewelry plans to make inroads into China this year as well after establishing its presence in Japan. The group`s agency said that in China, Jewelry would focus more on live concerts and directly meeting Chinese fans than on releasing albums.
