The Japan Institutional Gateway (JIG) is a platform that enables researchers based in Japan to make their papers open access quickly and transparently. A distinctive feature, especially in the humanities and social sciences, is that it supports submissions in Japanese, allowing research results to be disseminated in both English and Japanese.

This initiative was launched primarily by the University of Tsukuba and now involves multiple universities. Hiroshima University has been participating since May 2025.

We encourage all researchers at our university to take advantage of this opportunity.

• Immediate Publication: Share research results promptly by publishing papers before peer review 
  *Note: APC payment is required before preprint publication.
• Research Data Sharing: Make research data publicly available for secondary use
• Open Peer Review: Ensure high transparency by making the review process open
• Support for Japanese Papers: In the humanities and social sciences, papers can also be published in Japanese
• Indexed in International Databases: Peer-reviewed papers are indexed in Scopus, PubMed, and other major databases
