Yamazaki will be playing the role of Daichi who is Koichi's son and had failed to find a job after graduating from university. Lacking in passion and losing interest in things very quickly, he tries to resume his job search while helping out in the family business. Upon seeing how his father and his employees try to rejuvenate the family business, Daichi becomes a changed person and is even tasked to produce the patented sole part of their Rikuou brand of running shoes. Yamazaki commented that as he is of the same age as Daichi i.e. 23 years old, he can understand Daichi better especially since he is frustrated at not being able to do the things he wants to do.
In conjunction with the production of this drama which is shot on location at Gyoda City, there is a picture of Yakusho and the drama's title made from the rice fields which is currently available for viewing by the public.
