Kachou Shima Kousaku

Kousaku Shima is a salaryman working as a section chief at Hatsushiba Electric in Tokyo. At 34 years old, he is doing well for himself and his family, and his loyalty to the company seems to be paying dividends for him. However, despite his apparent success, appearances can be deceiving.

Behind the scenes, Kousaku has a habit of mixing business with pleasure. He is popular with women in and around the company, and he cannot bring himself to say no when the opportunity presents itself. In addition, he finds himself involved in some serious scandals and power struggles within the corporation—several of which he cannot avoid.

As his affairs stack up and his reputation increases, Kousaku is exposed to different sides of Japanese corporate culture that he never knew existed or even really cared for. From struggling to find the right balance between work and play to questioning the morality of his decisions, each day is just another piece of business to take care of for Kousaku Shima, Section Chief.
