Top Hallyu girl group KARA has solidified their 'Hallyu Princesses' status by extending their Japanese contract with Universal Music.

A representative from KARA's management company DSP Media was quoted saying, "KARA's initial contract with Universal Music Japan was signed in August of 2010 and is set to expire this August. We have successfully extended the contract by a year and four months, meaning that the contract will run until December of 2013."

Furthermore, as a testament to their continual popularity in Japan, KARA recently sold out all the seats to their upcoming Japanese tour.

The DSP representative explained, "Starting with Yokohama on April 14th, the tour will take place in five different cities for a total of 10 performances. There were 100,000 available tickets for the tour, which all sold out upon its opening sale. In response to this explosive interest, we added two additional performances for May 26th and 27th at the Saitama Super Arena, which seats 15,000 people."

In related news, KARA is currently busy preparing for their Japanese tour while they promote for their 6th Japanese single, "Speed Up/Girl's Power".
