It's been revealed that ANGERME's Aikawa Maho will be going on hiatus. 

On Aikawa's hiatus, the group's official website explains, "She's been having symptoms of headaches and dizziness from before, but more recently, these symptoms have become stronger and more frequent. After seeing a doctor, she was diagnosed with panic disorder."

Aikawa requires rest and medical treatment for a period of time. She will resume her activities once her condition has settled down.
