Division Chief Kosaku Shima

Kiichi Nakazawa, the president of Hatsushiba Electric and Kosaku Shima’s longtime mentor since their days together in the sales division, anticipates a fierce factional power struggle following his impending resignation. To protect Shima from the inevitable corporate warfare, Nakazawa transfers him to Hatsushiba Trading, an affiliate company. Shima assumes the role of representative executive director and immediately immerses himself in a high-stakes venture, negotiating directly with a prominent wine producer in France. His new position demands relentless international travel as he shuttles between Japan, France, and England, determined to source exceptional wines and secure the most profitable deals possible. As always, Shima does not navigate these professional challenges alone. He relies on the indispensable support of several influential women who help advance his ambitions. Among them is Kumiko, his trusted subordinate and longtime romantic partner, whose dedication proves vital to his operations. He also benefits from the extensive global connections of Kumiko’s mother, a woman deeply embedded within elite international circles. Additionally, a mysterious hostess working at an intimate bar in Shinjuku provides crucial insider knowledge regarding key figures in the wine industry. Together, this network empowers Shima to overcome obstacles and thrive in his demanding new role.
