Kiyoshi Matsuura was so worried about growing old that he started using an anti-baldness treatment as a teenager.
It was an obsession that went on to define his life. The Japanese entrepreneur continued to experiment with various supplements and other products, and founded his own company dedicated to fighting the ravages of time about 12 years ago.
Premier Anti-Aging Co. went public in Tokyo in October, and quickly became one of Japan’s best-performing stocks. It’s more than tripled since listing, boosting the value of Matsuura’s stake to $817 million (¥89 billion).
