Middle-aged salaryman Shigeru Yamasaki works at a Japanese trading company, where his eccentric behavior and completely unconventional approach to routine tasks make him stand out in the structured corporate environment. Despite viewing himself as a diligent employee, he constantly finds himself in absurd yet relatable situations, whether dealing with demanding bosses, unrealistic deadlines, or the peculiarities of office politics. The core dynamic revolves around Shigeru’s relationship with his long-suffering but deeply understanding Bucho, the department manager, who patiently tolerates his subordinate’s unpredictable antics and bewildering problem-solving methods.

The narrative unfolds through episodic vignettes, each highlighting a different facet of Shigeru’s daily life. At the office, he interacts with colleagues such as the ambitious and competitive Tanaka and the laid-back yet insightful Nakamura. Outside of work, Shigeru’s personal life adds another layer of chaos as he navigates his relationship with his wife, who often questions his decisions, and his young son, who looks up to him despite his many flaws. His occasional attempts at self-improvement, whether through hobbies, fitness, or chasing a promotion, typically end in comedic failure.

The series explores themes of work-life balance, societal expectations, and the quiet pursuit of happiness, using exaggerated yet grounded humor to reflect on the absurdities of modern office culture. The tone balances its comedic moments with instances of gentle introspection, offering a nuanced portrayal of an ordinary man striving to find his place in the world. Each self-contained story emphasizes the contrast between Shigeru’s peculiar worldview and the rigid corporate structure he inhabits, ultimately creating a lighthearted and heartwarming look at the daily struggles of the everyman.
