In the drama, Shin says all his lines in Japanese, which he says helped him realize that language is just a means of communication and which had opened a new world to him.
Shin says he felt comfortable using Japanese while shooting the drama because the Japanese and Korean languages have much in common. The actor added that unlike Korean dramas, which are shot quickly but have longer scenes, Japanese dramas have shorter scenes and thus require more concentration.
The drama, "Mobile Phone Detective," is expected to boost Shin's popularity in Japan. Episodes featuring Shin will begin airing in Japan Feb. 23.
