From here, rough translation:
Akanishi Jin of KAT-TUN (25) will perform live in Los Angeles in June for two days (T/N: he'll be there for 24 days? maybe there's a typo in the article). These solo performances will be the first Johnny's artist in history to perform in the United States. KAT-TUN's decision to hold a concert tour of Asia in May-August. Even during the first month, Akanishi will not participate in the tour. The jimusho says that he will not leave the group, as that would be unusual, because of his solo career.
KAT-TUN and Akanishi Jin will both be going worldwide.
Beginning on July 16, there will be 31 days of tour, including Bangkok, Thailand and Seoul, Korea then back to the Kyocera Dome in Osaka, then to Taipei, Taiwan for this "BIG WORLD TOUR".
After the 8 consecutive days in the Tokyo Dome last year, this year they are challenging themselves with an overseas tour. There could also be a possible show in Hawaii, making them the first JE group to perform in the US.
Between May 2 and June 27, known as the "Arena Tour" there will be a total of 21 performances in 10 cities. Akanishi will be unable to attend. Kame comments about One member (Jin), having this chance and that he should hold onto it tightly and make the most of this situation.
