The Japanese Proteomics Society (JPrOS), also associated with the Japan Human Proteome Organization (JHUPO), is a scientific organization that supports the development and wider adoption of proteome analysis technologies and promotes proteomics research in humans and model organisms. Its activities bring together researchers from academia, industry, and government to advance the field and share knowledge. The society provides a forum for scientific exchange through annual meetings, conferences, and other academic events, and publishes Proteome Letters, a journal featuring research in proteomics.

It also offers training courses to help participants develop relevant knowledge and skills. Members and other interested readers can access society news, event information, research publications, award announcements, and updates on initiatives and specialist groups. The organization recognizes achievements through its society awards and provides information about membership, corporate members, its history, and its governance.

Through these resources and activities, JPrOS connects the proteomics community and encourages collaboration in research and technology development
