The company's history page records that in 1977 Peptide Institute, Inc. was established and Shunpei Sakakibara became its first president. In 1983, all peptide synthesis operations were transferred from the Protein Research Foundation to Peptide Institute, Inc. In 1990 the company obtained a pharmaceutical manufacturing license. In 2006 it established the Saito Laboratory (in Ibaraki City, Saito) including GMP-compliant facilities. In 2018 Masahiko Tsunemi became president.
