Kihachiro Onitsuka / 鬼塚喜八郎 (May 29, 1918 – September 29, 2007) was a visionary Japanese entrepreneur and the founder of ASICS, a brand that would come to symbolize the merging of athletic performance, social responsibility, and humanistic ideals. Born in Tottori Prefecture, Japan, Onitsuka grew up in a modest family during an era marked by economic uncertainty and national upheaval. The values of perseverance, discipline, and community shaped his upbringing and would later inform his approach to both business and life.
Following his education and service in the Imperial Japanese Army during World War II, Onitsuka returned to civilian life with a renewed sense of purpose. Witnessing the psychological and physical toll the war had taken on Japanese youth, he became convinced that sport could serve as a powerful tool for recovery and renewal. He believed that engaging young people in athletics would not only rebuild physical health but also instill character and unity in a generation struggling with disillusionment.
In 1949, Onitsuka founded Onitsuka Co., Ltd. in Kobe, initially working out of his own home with limited resources and little experience in shoemaking. His mission, however, was bold and clear: to improve the lives of Japanese youth through sport. The company’s first product, a basketball shoe, was a result of tireless trial and error. Onitsuka studied the feet of athletes, the biomechanics of movement, and even food-related metaphors to inspire his designs. In one famous story, he was inspired by the way octopus tentacles gripped a salad bowl, leading to the suction cup–like soles in his early prototypes.
These early designs laid the foundation for a new kind of athletic footwear, focused not only on performance but on the well-being of the athlete. In 1951, his shoes gained attention when the Kobe High School basketball team wore them to victory. Word spread quickly, and Onitsuka’s commitment to innovation, comfort, and athlete feedback earned his company a growing following across Japan. By the mid-1950s, Onitsuka Tiger—as the brand came to be known—expanded into running and other sports, culminating in its international breakthrough during the 1960s.
One of the pivotal moments in his career came through his collaboration with a young American athlete and businessman, Phil Knight. Knight became the U.S. distributor of Onitsuka Tiger shoes and later went on to found Nike. Though their partnership eventually ended in a legal dispute, it played a crucial role in introducing Onitsuka’s designs to the global market and laid part of the groundwork for modern sportswear branding.
Onitsuka’s philosophy extended beyond business metrics. In 1977, Onitsuka Tiger merged with two other companies to form ASICS, an acronym for the Latin phrase Anima Sana In Corpore Sano—“A Sound Mind in a Sound Body.” This encapsulated his belief that sport was not just about competition but about cultivating balanced, healthy individuals. Under his leadership, ASICS became known for its scientific approach to footwear, establishing research facilities and investing in biomechanics long before such practices became industry standards.
Even after stepping down from day-to-day management, Onitsuka remained an influential figure in Japanese business and philanthropy. He authored several books and was widely respected for his ethical business approach and commitment to social betterment. His contributions to postwar Japan were recognized both domestically and internationally, and he was frequently cited as a model of how entrepreneurial vision could align with public good.
Kihachiro Onitsuka passed away in 2007 at the age of 89, leaving behind a legacy that extended far beyond sneakers. He transformed the concept of athletic footwear in Japan and abroad, and more importantly, he proved that commerce, compassion, and community could thrive together. Today, ASICS continues to embody his founding ideals, promoting physical and mental well-being across the world—an enduring tribute to the man who saw in sport not just a game, but a path to renewal.
