In-Depth Profile

Early Life

Yoichi Erikawa was born in 1950 in Tochigi Prefecture, Japan. He graduated from Keio University with a degree in Commerce and Economics. After graduating, he decided to pursue his passion for programming after his family's rural dyestuffs business failed. Erikawa's interest in history, which he developed in high school, would later influence his career.

Rise to Success

Erikawa, along with his wife Keiko Erikawa, founded Koei in July 1978. Initially, the company focused on personal computer sales and made-to-order business software. However, Erikawa's personal interest in computer games led him to create a war game set in 16th-century Japan, titled Kawanakajima no Kassen, which sold 10,000 copies. Recognizing the demand for more games, he developed Nobunaga's Ambition in 1983, a historical simulation game that achieved significant success and established Koei's presence in the gaming industry. The game became the prototype for Koei's history simulation series.

Key Business Strategies

Koei Tecmo's success is rooted in its focus on historical simulation games, which catered to an adult audience. This strategic decision set the company apart in the market and allowed it to build a loyal customer base. The company also expanded its offerings to include popular action games like Dynasty Warriors and Samurai Warriors series. Erikawa's leadership was characterized by a commitment to innovation and quality, which became hallmarks of the company's brand.
