Japan’s first full-fledged preprint server Jxiv to be operational

These updates are republished press releases and communications from members of the Science|Business Network

The Japan Science and Technology Agency (JST) plans to release Jxiv on Thursday, March 24, 2022. Jxiv is the first full-fledged preprint server in Japan that makes unpublished, pre-reviewed papers (preprints) openly available, in order to support rapid-release research results and promote open science.

Papers are one of the most common forms of presentation of research results and most of them are available via peer-reviewed academic journals. Since peer reviews and revisions are required as part of the journal’s publication process, it takes a certain degree of time from submission to publication, even several years in some cases. There has, thus, recently been a rapid increase in the number of preprints to be published before or at the same time as submission to journals, due to the situation under the COVID-19 pandemic in which the research community was urged to share results immediately. However, a full-fledged preprint server has not existed in Japan and the number of preprints submitted from Japan is still limited.

Therefore, JST has developed Jxiv as the first full-fledged preprint server in Japan. Jxiv allows users to submit and publish preprints in Japanese or English in all research fields, including interdisciplinary science, beyond the existing framework of natural sciences, humanities, and social sciences. There is no charge for submitting, publishing, and viewing preprints. An article is published as an open - access preprint attached with an international identifier DOI and easy-to-reuse license terms. Further, Jxiv accepts domestic and international submissions, but researchers are required to possess the researchmap or ORCID ID.

Preprints will be published promptly within a few days after JST screening (please note that preprints posted on Jxiv have not been reviewed by experts). Published preprints can be revised until they are reviewed and accepted in journals, and preprints will continue to be openly available in Jxiv even after they are published and released as peer-reviewed papers from the journal. In addition, it may be linked to the published version of the journal.

Jxiv offers researchers the opportunity to make public their research results ahead of peer-reviewed publication. It speeds up the cycle of feedback from the scientific community and not only accelerates research of researchers who have published preprints, but also stimulates the entire scientific community.
