Celtic have signed defender Hayato Inamura from Albirex Niigata on a four-year deal.
The 23-year-old, who play as a left-sided centre-back but can also provide cover at full-back, had two years remaining on his contract with the J-League side.
He joined the relegation-threatened club from Toyo University in 2021 and secured a J-League Cup runners-up medal last season.
Hayato made 33 senior appearances in the J League and is yet to be called up to the Japan squad.
Celtic boss Brendan Rodgers said: “We’re delighted to bring Hayato to Celtic and we’re looking forward to working with him.
“He’s a young player full of promise and potential. I know that he’s delighted to be taking this next step in his career by joining us, and we look forward to welcoming him into the squad.”
