Popular Johnny's Jimusho idol group KAT-TUN are to become the first artists to play seven straight nights at the Tokyo Dome. The concerts will be during the baseball season, so they had to fit into the schedule of the Yomiuri Giants who are based at the venue. With four days of preparations and rehearsals, the venue will be taken over for 11 days. The seven shows, on May 15-21, will feature a different theme each night, probably in the hope that repeat attendance will help shift the 385,000 tickets. The one-week run will extend the record of four consecutive nights held by Sting (in 1988) and KAT-TUN themselves. The six-member group are all in their early 20s and age-wise they are one step behind fellow Johnny's artists Arashi.
