Celtic boss Ange Postecoglou is the benchmark managers in Japan are aiming for, according to Toru Oniki.
The Kawasaki Frontale boss was a frequent foe of Postecoglou's in the J-League before the Australian took the leap to Scotland.
The move was heavily scrutinised at the time but he won the Premiership in his first season and delighted Celtic fans with his scintillating brand of football.
