It was reported recently that KAT-TUN has released their new single Roar on various digital platforms including Spotify. At the time, the release was limited to Japan only, but today, in celebration of their 15th Anniversary, the region lock was lifted and it is now available for streaming internationally, including the digitally exclusive track Flashback.

To kick off festivities, theofficial Twitter account for Roar was renamed to KAT-TUN 15th Anniversary, and the colors representing ex-members have been added to the official Roar website, including a special message. Ex-member Taguchi Junnosuke posted his greeting on Twitter and even tagged fellow ex-members Tanaka Koki and Akanishi Jin. After a while, Tanaka Koki also posted his own greeting on his official Youtube channel. 

Tickets for archive delivery of KAT-TUN’s live 15th Anniversary online concert are still available on the official website until 22:00 on March 28th. You can watch as many times as you want from 0:00 on March 27th until 23:59 on March 28th.

Edit: After the ruckus, Akanishi Jin finally took to Twitter. His tweet seems to be about hay fever, but according to the fans in the replies, this is actually a pun as hay fever is pronounced as "ka-fun" in Japanese. KAF-FUN is currently trending in Japan.
