Japanese Journal of Political Science

Incoming editors Christina Davis (Harvard University) and Junko Kato (University of Tokyo) begin their tenure from January 2019, and will begin to take submissions from the 3rd September 2018. See the full Editorial transition Statement here.


Articles should be submitted via Editorial Manager.

The Journal welcomes the submission of materials that meet the goals of the journal as described in the editorial policy mission statement. Successful manuscripts will introduce innovative theoretical and empirical findings that shed light on important questions in the discipline of political science or draw upon other disciplines to offer insights on political behavior and institutions.

Manuscripts will normally receive at least two independent reviews. The peer-review process should generally issue a decision to authors within three months. All decisions are reviewed by a member of editorial committee and the editors-in-chief.

Articles may fall within three categories:

Research articles between 8,000-12,000 words that contain original theoretical and/or empirical contributions to political science.

Research notes between 4,000-8,000 words that address an ongoing debate with new evidence. Notes may consist of replication or reanalysis, introduction to a new dataset, or presentation of a case study. The journal will also consider “result-blind” submissions for special review that focuses on the research design.

Book review articles of approximately 1,200 words that provide a summary and analysis for recent publications (typically books published in last two years). We especially encourage the review of books written in Japanese that may not otherwise receive attention in English-language outlets.

All page length requirements must be confirmed with Microsoft Word or PDF word-count software including text, tables, figures, references, appendices, and endnotes. Supplementary materials for online publication may be excluded from the word-count and must be included with the original submission for the review process. Authors may refer readers to their own website for additional materials.

The Japanese Journal of Political Science is a refereed journal which adopts a double-blind reviewing system. JJPS will not publish material that has already been published, is currently under review at another journal, or is substantially similar to another publication; this policy applies to both print and online formats. Questions about submitting to the journal should be sent to the JJPS Editorial Office:

Articles should be submitted via Editorial Manager.

Please follow the online submission instructions for uploading files. You will need to provide a title page including author affiliation and contact information, an abstract (no more than 250 words), and an anonymous manuscript file that does not contain any information identifying the author. Self-references to unpublished materials that would reveal the author should be removed, although self-references to published materials may be included when removal would itself be more revealing of identity. You will also be prompted to provide keywords that describe the topics relevant to the paper and note any individuals whom you would like to recommend or exclude as potential reviewers. Do not recommend individuals who are advisers, students, co-authors or otherwise face a close relationship that would preclude objective review. These are important steps to facilitate assignment of reviewers.

Data and replication policy 

When an article has been accepted for publication, the author should submit a final version of the article. At this stage and prior to completion of page proofs for publication, journal policy requires that authors provide replication data and code for all quantitative analysis included in the article. This should be uploaded by authors to the JJPS Dataverse site, which can be found here.

See this guide to uploading files to the JJPS Dataverse

Citing data

To enable readers to access the data and code, provide a Data Availability Statement at the end of your article, which includes the DOI that is generated by Dataverse.

For example:

Data Availability Statement: Replication data for this article can be found in the JJPS Dataverse at:

In your reference list, please cite your replication data and any other data sources that are important to the paper to allow readers to find them in the future. Include the name and title of the dataset, the author information, the date of publication, the repository where the data is archived, any version information and the persistent identifier (e.g. DOI).

For example:

Whitten G, Williams L and Wimpy C (2019) Replication Data for: Interpretation: The Final Spatial Frontier,, Harvard Dataverse, V1.

Supplementary Material

Additional materials that are non-essential to the replication of the published results, but which could be of interest to readers, can be provided as supplementary material when you submit the article and published on the Cambridge Core platform.

Some notes on writing style and formatting:

Authors should write in a clear and engaging style that favors an active voice and minimizes the use of jargon and acronyms. Acknowledge sources with specific page references and full citation whenever appropriate.

Authors, particularly those whose first language is not English, may wish to have their English-language manuscripts checked by a native speaker before submission. This is optional, but may help to ensure that the academic content of the paper is fully understood by the editor and any reviewers. We list a number of third-party services specializing in language editing and / or translation, and suggest that authors contact as appropriate.

Please note that the use of any of these services is voluntary, and at the author's own expense. Use of these services does not guarantee that the manuscript will be accepted for publication, nor does it restrict the author to submitting to a Cambridge Core published journal.

At the review stage, tables and figures can be submitted in a separate file or included in text. For all tables and figures, include a title and caption with clear variable labels that describe in words the concept being measured. Indications of significance should follow standard convention with consistency and transparent explanation. In many cases graphic presentation of substantive effects will strengthen the presentation of quantitative results. Authors should avoid excessive use of tables to help readers focus on core findings while reporting additional results and information for specialists in online appendices.

Referencing: Harvard (author-year) system

Whenever you are quoting the exact words of another writer; closely summarizing a passage from another writer; or using an idea or material which is directly based on the work of another writer, you must identify and acknowledge your source in a systematic style of referencing. We recommend the Harvard system of referencing, and we require conformity with this standard for accepted articles, although we will accept other systems of referencing at the initial review stage.

There are two parts to the author-year system of referencing. References (author and year of publication) are briefly cited within the text (called embedded or in-text referencing), and then all of the resources referred to in the body of the writing are given at the end of the manuscript in the reference list. References should give full bibliographical details in the alphabetical order. Each item should include: full name (surname and first name) of the author, date of publication in parenthesis, title of the source e.g. such as book and journal in italics, place of publication and the publisher, and pages numbers if necessary.

Example of Citation and Reference

For citation, use the surname of the author and the year of publication. If there are two authors, cite both. If there are more than two authors, cite only the first followed by ‘et al.’, which means ‘and others’.

If an author has published more documents in the same year, distinguish between them by adding lower-case letters.

Example 1:

Benedict Anderson, a political scientist at Cornell University, has gone so far as to say that the American academic writing is targeted at narrowly defined professional audience and its style is "boring" to other potential readers (Anderson, 2009a, 2009b).

Example 2:

Just as Midland, Texas has brought up George W. Bush and Tommy Franks and thus shaped United States war policy in Iraq, Ann Arbor, Michigan has exemplified and thus arguably shaped quintessentially American political science. It is the trinity of robust academic professionalism, solid positivism and heavy methodological armory has been a trademark of American political science (Gunnell, 2004; Easton et al, 1995, Oren, 2003).

Footnotes and Appendices can be used where needed to expand or enforce your article. Footnotes need consecutive numbers through the whole manuscript.

Copyedit and Proof-check

After your manuscript is accepted, it will be copyedited and the first proof data (PDF) should be sent to the contributors. They are to be read and corrected by contributors. The contributors return the checked and corrected proofs by e-mail within seven days of receiving them. Authors will receive a PDF offprint of their article.
