Celtic are targetting moves for Japanese trio Daizen Maeda, Reo Hatate and Yosuke Ideguchi.
Manager Ange Postecoglou has already tapped into the J-League market with success, bringing in striker Kyogo Furuhashi from Vissel Kobe in the summer.
With the Celtic boss keen for reinforcements, left-back Hatate is due to meet Kawasaki Frontale club chiefs this week to express his desire to join the Scottish Premiership club next month.
The 24-year-old is out of contract in February but is hoping to agree a move to Scotland in the transfer window.
Maeda, who worked under Postecoglou at Yokohoma F Marinos, could reunite with his former manager in Glasgow with the Parkhead side keen on the striker.
The Japanese international ended the season in style by scoring on the final day of the season to become the top scorer in the J League.
Maeda has represented Japan twice including at the Olympic Games
Meanwhile, Ideguchi is also thought to be on Postecoglou’s January wishlist. The central midfielder is currently with Gamba Osaka in his native Japan, where he made 29 appearances last season.
The 25-year-old has previous experience of British football, after signing for Leeds United in 2017, though he never made an appearance in a competitive game.

Meanwhile, Sky Sports News understands that Celtic are expected to trigger Jota’s option-to-buy clause before the end of the season.
The winger has impressed since moving from Portuguese club Benfica in the summer, scoring eight goals in all competitions so far.
A fee of GBP6.5m was agreed in the summer with Celtic eager to take advantage.
Postecoglou has confirmed he will be without the 22-year-old for “a few weeks” after he suffered a hamstring injury in their 1-0 win against Hearts.
Vasilis Barkas has failed to impress since joining Celtic on a four-year-deal
One player set to leave Celtic in the January transfer window is goalkeeper Vasilis Barkas.
The Greece international has failed to impress since joining on a four-year deal in July 2020.
A number of Turkish clubs are believed to be interested in signing the Greece international who has not featured for Celtic since the signing of former England goalkeeper Joe Hart.
Jackson: Kyogo has raised expectations
Former Celtic striker Darren Jackson believes the supporters will be expecting any new signings from the Asian market to impress as much as Kyogo Furuhasi.
Speaking on Sky Sports News, former Celtic striker Darren Jackson said:
“If they are half as good as Kyogo then I think they’ll be very happy. He’s been a sensation since he arrived.
“The manager knows the market, he knows the players and he’s very confident in bringing them in, but expectation levels from the fans will grow because of Kyogo.
“When you look at the bench it’s not as strong as it should be. Trying to change things during a match has probably been quite difficult for the manager.
“Kyogo maybe does need a little rest but there’s no way they can give him a rest, so it’s very important they strengthen the squad in January.”
