Announcement regarding our talent Marius Yo (Sexy Zone)
We would like to thank you for your continued support.
Our talent Marius Yo (Sexy Zone) will take a temporary break from entertainment activities due to his poor health. We deeply apologise to all fans and third parties who have always supported him for causing concern. We are truly sorry for the suddenness of this announcement.
Marius has been ambitiously striving to work in the entertainment industry alongside his studies, and his interests which go beyond the scope of his major have led him to deepen his learning. Our company has endeavoured to listen carefully to Marius as much as possible regarding his work, and made adjustments to his work and study balance whenever possible.
However, based on discussions with Marius and the results of his medical examinations, it is undeniable that his sincere ambition to achieve perfection in everything he does has placed excessive pressure on himself. Recently this has led to the deterioration of his physical and mental balance in his social life, including his work and studies.
From our point of view and after hearing Marius' own wish the first priority now is for Marius to make a full recovery both physically and mentally, so it is for this reason that he will take a temporary break from entertainment activities. We appreciate that this is painful to hear for fans who were looking forward to seeing Sexy Zone as a group of five and to all those involved, but we ask for your understanding. We hope you will keep on warmly supporting Sexy Zone as they continue activities as a group of four - Sato, Nakajima, Kikuchi and Matsushima.
We once again deeply apologise for causing concern.
