Celtic's Australian manager Ange Postecoglou led his side to their 52nd Scottish title on Wednesday, securing it with a 1-1 draw to Dundee United.
Celtic's Giorgos Giakoumakis and Dundee's Dylan Levitt were the scorers at Tannadice Park. Japanese midfielder Reo Hatate started for Celtic, while Daizen Maeda and Kyogo Furuhashi came off the bench.
"I've worked really hard on my defense ever since I came here," said Hatate, who joined from Kawasaki Frontale on a four-and-a-half year contract on New Year's Eve. "So I think I was able to contribute that way."
Postecoglou recruited four J-League players after he moved from Yokohama F Marinos last June. Furuhashi left Vissel Kobe to join Celtic in July, while Hatate, Maeda and Yosuke Ideguchi joined during the January transfer window.
Celtic's 10th league title in 11 years booked them a place in next season's Champions League group stage.
