Everybody knows that Rajinikanth is Asia's biggest star and he has fans across the world so it has been decided that Kochadaiyaan should be a truly international film. It is going to be made in Tamil, Telugu, Hindi, English and Japanese.
Ever since Muthu directed by Ravikumar and starring Rajini and Meena was dubbed and released in Japanese as Dancing Maharaja, Rajinikanth has enjoyed a firm fan bastion in Japan. And hence the decision to make a Japanese version was made by Soundarya Ashwin.
