Based on an award-winning novel by Kitagawa Emi, Solomons Perjury director Narushima Izurus To Each His Own touches on a trouble that many people in Japan can empathize with: overwork. Kudo Asuka (A Loving Husband) plays a passive salaryman beleaguered by long hours & an unreasonable boss at an exploitative "e;black company, "e; while Fukushi Sota ( Blade of the Immortal) is a mysterious friend who becomes his guiding light.
Mentally battered from overwork, tired salesman Aoyama Takashi (Kudo Asaka) blanks out momentarily at the train station & almost gets hit by a train. He is saved by a man named Yamamoto (Fukushi Sota), who speaks in an Osaka dialect & claims to be his childhood friend. Aoyama, however, has no memory of him at all. After meeting the bright & smiley Yamamoto, Aoyama begins to recover his smile, & his work results also improve. One day, Aoyama learns that Yamamoto committed suicide three years ago. Then who is this man before him claiming to be Yamamoto?
