Celtic have moved to bolster their squad with three players from the Japanese J League.
Daizen Maeda, Yosuke Ideguchi and Reo Hatate have all signed for the Scottish Premiership club.
They will link up with the squad in January, once all the necessary administration has been completed.

Postecoglou has experience in the J League from his time in charge of Yokohoma F Marinos - the club from which Daizen Maeda joins.
Maeda - a forward - played under Postecoglou during his three-year spell with the club.
He joins initially on loan - but there is a compulsory purchase order in the deal.
25-year-old midfielder Yosuke Ideguchi has been capped on 15 occasions for Japan, and joins from Gamba Osaka.
The third new signing, Kawasaki Frontale's Reo Hatate, has been described by Celtic as a 'versatile' player who can operate in a variety of positions.
“We are really pleased to bring in these guys to Celtic and I think they are players who will excite our fans," Postecoglou said.
"Clearly I am well aware of their attributes and I think in bringing all three to the club we are bringing even more quality, personality and energy to the squad to work with the players who have done so well for us already this season.
“They are all really at the peak of their careers, ambitious to achieve more success and I am sure at this particular time we will be getting their best years.
"I am delighted to have secured these players so early in the transfer window, I look forward to working with them and myself, my backroom team and the rest of the squad will be making sure we help them settle into Celtic as quickly as possible.”
Celtic are second in the Scottish Premiership as the winter break continues.
Their next league encounter is on January 17th against Hibernian.
