On Friday, popular boy band KAT-TUN completed their record-setting run of eight consecutive days of concerts at the Tokyo Dome. With a full house of about 55,000 fans at each show, a total of roughly 440,000 people attended the concerts.

Last year, KAT-TUN performed four consecutive days at the Dome. At the time, it tied for the record with British rocker Sting, who also did a four-day stretch there in 1988. However, KAT-TUN's recent concerts have now doubled that record.

Their management agency, Johnny's Jimusho, is hoping to have this achievement officially recognized as a Guinness World Record under "most consecutive concerts at a venue with a capacity of 50,000." It appears that someone affiliated with Guinness happened to be at the Tokyo Dome, so the agency has requested verification of the record.

With the success of these concerts, KAT-TUN has scheduled many more to extend their tour. They had originally planned for these 8 shows to be followed by 3 at Osaka Dome on May 29-31 and 2 more at Tokyo Dome on June 14-15. They have now added 17 more shows in 6 other cities, starting in July.
