Yusaku Maeyamada (40 years old) works at a copy machine company, and his mornings start with a gulp of oshiruko. Every day I respect the teachings of my predecessors, great managers, and think about the meaning of work. However, such a daily life suddenly collapsed. A devastated Tokyo, a shaking office, and human nature exposed. What is being questioned now is the pride of an office worker. Survival of a businessman who continues to ask "What does it mean to work?" and "What does it mean to live?" in extreme conditions!
