Newcastle United have confirmed the signing of Muto on an initial four-year contract - where he will be the first Janapese Newcastle United player in the club's history.
It is believed that Mainz will receive £9.5m for the striker.

In a statement on Newcastle's website, boss Muto revealed his delight to have signed.
“I am very happy to be a player for Newcastle United. I am really looking forward to playing in front of the fans.
“As the first Japanese Newcastle United player, I am honoured to be a player for such a big club. I hope to achieve good results – that is what I am here to do. I would like to perform well and leave my name in Newcastle’s history.”
Manager Rafa Benítez added: “I am really pleased to have Yoshinori Muto with us. We were following him for quite a while.
“Hopefully he can bring us his energy and work-rate and help the team to improve and be better for the new season.”
He becomes the fifth player to sign for the 'Magpies' ahead of the new Premier League campaign, following the permanent arrivals of Martin Dúbrvaka, Ki Sung-yueng and Fabian Schär, and the loan capture of Kenedy.
