History
1951 Rigaku was founded by Dr. Yoshihiro Shimura.
1952 The core innovation of the company was the introduction of the world's first commercially available rotating anode X-ray generator.[3][4]
1954 Rigaku introduced the first automatic-recording X-ray diffractometer.
1976 Rigaku developed the first parallel-beam type X-ray diffractometer for stress analysis, as well as the first X-ray fluorescence spectrometers capable of carbon analysis (1976) and boron analysis (1981).
2021 Rigaku announced that the global investment firm The Carlyle Group (NASDAQ: CG) and Mr. Hikaru Shimura, Chairman of Rigaku, agreed to jointly acquire all outstanding shares of Rigaku, through a holding company to be newly set up by Carlyle and Mr. Shimura. Carlyle is expected to own approximately 80%, and Mr. Shimura approximately 20% of the new entity.[5]
Today, the company is led by Mr. Jun Kawakami (President & CEO).[6]
