About the Institute

 

  The Ohara Institute for Social Research was established in February of 1919 following the conclusion of World War I. In 1949, following the conclusion of World War II, the Institute merged with Hosei University and subsequently moved to the University’s Tama Campus in 1986.

 

  The Ohara Institute for Social Research is one of Japan’s leading centers for scholarship on social and labour issues. The archives and resource center are open to all, regardless of academic qualifications or affiliations. The Institute also participates in international exchange with labour archives abroad as a member of the International Association of Labour History Institutions (IALHI).

 

  The Institute celebrated its centennial in 2019 and is committed to extending its illustrious, century-plus history as a center for social and labour research into and beyond the twenty-first century.

 

  We are grateful for your continued support and welcome feedback from visitors.
