Arashi's New Single will be released in February

For the first time, they will do a song for a drama, Ouroboros, without any members of Arashi included in its casts. However, the drama stars the two "bestfriends" of MatsuJun, Oguri Shun and Ikuta Toma. (Will there be a cameo for Jun here?)

The new single is entitled, "Sakura" and will be released on Feb 25, 2015.

It is a mystery drama where Ikuta Toma plays a detective while Oguri Shun is a yakuza. Both of them tries to unravel the dark side of the police organization.

Ueno Juri is also included in the drama. Ueno Juri + Ikuta Toma + Oguri Shun, now that's what you call an epic drama. But we'll see its true greatness once it started airing on January 16.
