"Faith: The Great Doctor" was selected as the best Korean drama in Japan.
The SBS drama starring Lee Min-ho broadcast two years ago received the first prize in the Korean drama section of "GAYO Entertainment Awards 2014" on Monday.
The winner was selected based on the yearly sales of "GAYO store," Japan's largest video streaming site that takes up about 80 per cent of the video clip service industry.
The drama's success was mainly due to the popularity of the male lead Lee and his character, Gen. Choi Young of the Goryeo Dynasty, in the drama.
"Lee's continuous popularity in Japan seems to have led to the success of his drama as well. The motif and the plot of drama are also favoured by the Japanese," an official of the Korean drama-distributing firm was quoted as saying.
"The loyalty and faith of Lee's character seemed to attract viewers of Japan. Also, the character's pure and delicate emotions expressed in the drama allured the fans as well," he added.
The 27-year-old heartthrob has finished filming his first lead-role action film "Gangnam Blues," which is scheduled to be released in January.
