* Submissions shorter or longer than the required range may be reviewed at the discretion of the editorial board, contingent upon the quality of the manuscript.
Required components:
Title
The title should clearly and accurately reflect the contents of the manuscript.Abstract
Maximum 200 words. The abstract should clearly state the manuscript’s main argument, methodology, academic contribution, and implications.4–6 keywords
Keywords should be as specific as possible to the topic of the manuscript.Proper citations and bibliography (described in detail below)

Page numbers in the upper-right corner
No author name(s) or identifying information should be present in the submitted document ot the file metadata
If your manuscript has figures, you are encouraged to submit them as high-resolution, separate files.
The authors are highly encouraged to thoroughly read through the following two sections (Style and Citation Style) and make sure the submitted manuscript follows the regulations, especially regarding citations. Manuscripts with excessive deviations from the journal’s style requirements may face disadvantages or delays during the publication process
Additional requirements for data features:
For authors submitting a Data Feature, they must additionally submit the following components:
(1) Raw Dataset File
Accepted formats:
Microsoft Excel (.xlsx)
Stata (.dta)
R data files (.rds or .csv)
Requirements:
The dataset must be cleaned and analysis-ready
Each row should represent a single observation
Each column should represent a clearly defined variable
Variable names should be consistent with those used in the codebook
Missing values should be clearly indicated and consistently coded
(2) Dataset Summary Table
The dataset summary table should provide a concise overview of the dataset’s structure and key characteristics. The summary table may include:
Number of observations (N)
Number of variables
Unit of analysis (e.g., country-year, individual respondent, etc.)
Temporal coverage (time period)
Spatial/geographic coverage
Key variables (brief description of main variables)
Data sources
Any notable limitations
Accepted formats:
May be submitted as a table in Word, Excel, or PDF.
Should be clear, concise, and easily interpretable
(3) Dataset Codebook
The dataset codebook should provide detailed documentation of all variables included in the dataset. The codebook should serve as a clear manual to users attempting to use the raw dataset.
For each variable, authors may include:
Variable name
Variable label/description
Variable type (e.g., numeric, string, categorical)
Coding scheme (e.g., 1 = Yes, 0 = No)
Units of measurement (if applicable)
Source of the variable (if drawn from external data)
Notes on construction (e.g., transformations, aggregations, recoding)
Additional requirements:
The codebook must correspond exactly to the submitted dataset
All variables included in the dataset must be documented
Ambiguities in coding should be avoided
Accepted formats:
May be submitted as a table in Word, Excel, or PDF.
Note:
Authors are strongly encouraged to ensure that their dataset is reproducible, transparent, and reusable.
Authors may also submit replication codes (e.g., Stata do-files, R scripts) to clearly demonstrate their data construction steps and facilitate other researchers’ understanding and use of the author’s dataset.
Authors are responsible for ensuring that:
o The dataset does not violate privacy, confidentiality, or data protection regulations.
o Proper permissions have been obtained for all data used.
o All sources are appropriately cited.
o Sensitive or restricted data are clearly indicated.
Style
American English spelling (e.g., “center,” not “centre”). Consult the latest edition of the Merriam-Webster’s Collegiate Dictionary when in doubt.
Our journal uses the Oxford Comma. Example: “My favorite breakfast foods are eggs, muffins, and toast.”
Names should appear in full (first name, surname) the first time they are mentioned. For any mention of it thereafter, surname alone should suffice. Example: “According to scholar Eunice Jeon, the theory of semiotics alone cannot account for this pattern. Jeon points to the cultural imperialism of the United States…”
Acronyms and abbreviations should be used when a term appears repeatedly throughout the text. When the term is used for the first time, always provide the full term. (e.g. General Agreement on Tariffs and Trade (GATT)). If a term appears only once OR it is well-known (e.g., NATO, UN, GDP), no abbreviation is necessary. No periods should appear in the acronyms (i.e. US not U.S.).
Refrain from excessively relying on endnotes to provide extra information. Authors are encouraged to only use endnotes for citation and provide in-text clarifications.
Non-English terms used as subject-specific concepts or left untranslated should be italicized on first use, followed by an English translation in parentheses (e.g., Realpolitik [power politics], Juche [self-reliance]). When italicizing, only italicize common nouns. Do not italicize proper nouns, including the names of people, places and government bureaus.
Avoid contractions (i.e., use “do not” instead of “don’t”).
Avoid using the following vocabulary: highly specialized jargon, colloquial expressions (e.g., “at the end of the day,” “in a nutshell”), slang, gender-biased language (e.g., policemen, mankind), dramatic vocabulary (e.g., always, never, the best, perfect, extremely, obviously).
Use the following Romanization systems for Asian languages:
Japanese – Revised Hepburn | Korean – Revised Romanization | Chinese – Pinyin |
新聞 shinbun | 조선 Joseon | 皮袄 pi’ao |
案内 annai | 먹었다 meogeotta | 朋友 péngyou |
Citation Style
YJIS follows The Chicago Manual of Style (18th edition), using the notes and bibliography system (endnotes). The full official Chicago Style guidelines are available on the official website.
(Note: Beginning with the Spring 2027 Call for Papers, YJIS will adopt the APA 7th edition citation style.)
Endnotes only: Use numbered endnotes (not in-text citations). The difference between endnotes and footnotes: endnotes are collected at the end of the document while footnotes are placed at the bottom of the page. Endnotes should be formatted as Calibri, 8-point.
Bibliography: A full bibliography should be included at the end of the article. Please make sure that every cited source has a corresponding bibliography entry.
Authors must include the DOI for each reference for which one is available. DOIs should be presented as complete links in the reference list. Authors are responsible for verifying that all DOIs are accurate and lead to the cited sources.
