The official website for the seiyuu unit Sphere has announced that the unit will enter a "recharging mode" (taking a break / hiatus) and will suspend group activities, which will take place after their live tour in summer, to prepare for their upcoming 10th anniversary.

Sphere consists of four seiyuus: Haruka Tomatsu, Minako Kotobuki, Ayahi Takagaki, and Aki Toyosaki. The unit began their activities in February 2009 and sung theme songs for many anime series such as Otome Youkai Zakuro, Hanasaku Iroha, Arata Kangatari, Soushin Shoujo Matoi, and more. Even though there will not be any CD releases nor live concerts from the group, each member will still remain active as a seiyuu artist.
