Giants in history
Japanese biochemist Akira Endo (1933 – 2024) discovered the first statin, called mevastatin, which lowered cholesterol levels in the blood by inhibiting a key enzyme in the cholesterol biosynthesis pathway. His work laid the foundation for the development of statins to help patients lower their blood cholesterol levels and reduce their risk of heart disease or stroke.
Ruby Sakae Hirose (1904 – 1960) was a Japanese-American scientist whose research contributed significantly to our understanding of blood clotting, allergies and cancer.
Haisako Koyama (1916 – 1997) was a Japanese solar observer whose dedication to recording sunspots – cooler parts of the sun’s surface that appear dark – produced a sunspot record of historic importance.
Michiaki Takahashi (17 February 1928 – 16 December 2013) was a Japanese virologist who developed the first chickenpox vaccine.
Toshiko Yuasa (11 December 1909 – 1 February 1980) was the first Japanese female physicist whose research on radioactivity shed light on beta decay – the process in which an atom emits a beta particle (electron) and turns into a different element.
Baron Kitasato Shibasaburo (29 January 1856 – 13 June 1931) was a Japanese physician and bacteriologist whose work led to a new understanding of preventing and treating tetanus, diphtheria and anthrax.
By isolating soil microorganisms and studying the compounds they produce, Satoshi Omura (born 1935) discovered almost 500 organic compounds with unique properties that were produced by these microorganisms, including many new antibiotics.
Husband and wife team, Kimishige (3 December 1925 – 6 July 2018) and Teruko Ishizaka (28 September 1926 – 4 June 2019) discovered the antibody class Immunoglobulin E (IgE) that triggers allergic reactions. They also discovered that IgE antibodies attach to white blood cells, known as mast cells, releasing histamine, which causes allergic reactions.

Reiji Okazaki (8 October 1930 – 1 August 1975) and Tsuneko (7 June 1933) were a Japanese couple who discovered Okazaki fragments – short sequences of DNA that are synthesized during DNA replication and linked together to form a continuous strand.
In 1915, Koichi Ichikawa along with pathologist Katsusaburo Yamagiwa became the first to prove that chronic exposure to chemicals can cause cancer.
