JMA Journal’s peer review process depends upon the professionalism of its volunteer reviewers. All reviewers are experts in the field of research; therefore, they are in the best position to judge the quality and importance of the work submitted to JMA Journal. The names of the reviewers remain unknown to the authors, as JMA Journal operates a single-anonymized review throughout the review process.　

I. Peer Review Process

1. The author submits a manuscript and it receives a manuscript identification number.
2. The Support Office performs a technical evaluation to check the manuscript’s formatting and style is in accordance with the Instructions for Authors.
3. An editor screens the manuscript and decides whether or not to send it for full peer review. If the decision is not to send the manuscript for review, the editor sends a decision letter via e-mail with the decision of immediate rejection.
4. If the editor decides to send the manuscript for a full peer review, the editor assigns generally 2 external reviewers to evaluate the manuscript.
5. Reviewers agree to review the manuscript.
6. Reviewers submit their reports to the editor.
7. The editor reviews the reviewers’ reports and makes a decision.
8. The Support Office contacts the author with the decision.
9. If the author receives the opportunity to revise the paper, he/she revises the paper according to the review comments and resubmits. The paper then goes through the same process above, but the editor may choose to accept the paper without further review by the reviewers.

JMA Journal expects that peer review is fair, unbiased and timely. Decisions to accept or reject a manuscript for publication are based on the manuscript’s importance to the field, originality and clarity in expression, the study’s validity and its relevance to JMA Journal’s scope and aim.

JMA Journal supports and adheres to the guidelines and best practices including Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals (http://www.icmje.org/icmje-recommendations.pdf) by the International Committee of Medical Journal Editors (ICMJE) and the Principles of Transparency and Best Practice in Scholarly Publishing (a joint statement by the Committee on Publication Ethics [COPE], the Directory of Open Access Journals [DOAJ], the World Association for Medical Editors [WAME] and the Open Access Scholarly Publishers Association [OASPA]; http://doaj.org/bestpractice).

The points below provide general guidelines for reviewing. Please read the instructions and required ethics and policy statements, along with the journal instructions thoroughly. If you have any questions, please contact the JMA Journal Support Office.

3. Confidentiality
The review process will remain strictly confidential.

• Do not discuss or mention, in any way or to anyone, the contents of the paper before or after the review process.
• The manuscript submitted for peer-review is a privileged document. All materials must be treated in confidence. If additional advice from a colleague or any parties is thought to be helpful, please contact the Support Office in advance to obtain permission from the editor. Do not pass the manuscript on to your colleagues or other third parties without first obtaining consent from the editor.

If you determine that you have a bias during the review of the paper, please contact the editor immediately.

6. Competence
You should accept an assignment only if you have adequate expertise to provide an authoritative assessment. If you think certain aspects of a manuscript are outside your expertise or realize that your expertise is limited, you should contact the Support Office so that we can decide whether you should continue and address your areas of expertise only or whether to assign an alternate reviewer(s).

7. Manuscripts You Have Previously Handled
If you are invited to assess a manuscript you previously reviewed for another journal, please consider the manuscript as a new submission. In such case, the authors may have made changes according to the previous review comments, and the JMA Journal’s criteria for evaluation may differ from those of the other journal.

The invitation includes manuscript details, such as the title, the names of authors and the abstract, which may help you to determine whether the subject of the manuscript is within your areas of expertise.

If you are unable to agree to review a manuscript, please click the decline link in the e-mail. In such cases, it would be appreciated if you suggested another potential reviewer.

If you click the link to accept the invitation to review a manuscript, you will receive a notification via e-mail about how to log-in to our online system to access the manuscript in PDF or HTML format, and instructions for submitting your comments through the online system.

2. Revised Manuscripts
The revised version of a manuscript is normally sent back to some or all of the original reviewers for re-review. If you are assigned to review a manuscript you previously reviewed, please ensure that changes requested in the original review have been made, rather than raising additional issues.
