Tohru Kino
Tohru Kino is a Japanese chemist and pharmacologist, best known for his discovery of tacrolimus.
While working for Fujisawa Pharmaceutical Company in the 1980s, Kino and his colleagues found that FK-506, which is produced by the soil bacterium Streptomyces tsukubaensisis, could be expected to be an immunosuppressive drug.
For his achievement, Kino received the Prime Minister Award from the Japan Institute of Invention and Innovation in 2004.
