Kosaku Shima depicts the life of Kosaku Shima, a salaryman, a Japanese white-collar worker who devotes his life to his company. 
At the start of the long-running series, Shima K&#333;saku is a kach&#333;, or section chief, of a huge conglomerate, Hatsushiba Electric. He is later promoted to buch&#333; (division chief) and eventually promoted to manager and executive-director, and with each promotion the title of the series changed as well. He is now promoted to the president of Hatsushiba Electric. And the title changed "Shach&#333;" Shima K&#333;saku, which means "President K&#333;saku Shima". 
The fictional conglomerate is modeled after Panasonic, or Matsushita Electric, where Hirokane worked before and is highly accurate in its portrayal of Japanese corporate culture.
