In 2014, Dr. Shuji Nakamura, along with two other scientists, was awarded the Nobel Prize for Physics for his work in creating bright blue LEDs. In 1993, Nakamura held only a master’s degree and worked with just one lab assistant for a small manufacturer in rural Japan, yet he was able to find a solution that had eluded some the highest paid, best-educated researchers in the world.

If his story ended there, he would no doubt be the poster boy for Japanese innovation and never-say-die spirit, but in the years since his discovery, he has instigated a landmark patent case, emigrated to the US, given up his Japanese citizenship and become a vocal critic of his native country. Last week, the prickly professor gave his first Japanese press conference since picking up his Nobel and he had some very succinct advice for young Japanese: Leave.
