How to Write an Abstract for an International Journal: A Guide for Japanese Researchers

For Japanese graduate students and junior faculty preparing to submit to an international peer-reviewed journal, the abstract is one of the most consequential sections of the manuscript. It's also one of the most frequently underestimated. A poorly written abstract causes many editors to reject a manuscript before peer review begins. A well-written abstract gets your paper through initial screening and into the hands of reviewers who can evaluate the quality of your research on its merits.

This guide explains how to write an abstract for an international journal, step by step, with specific attention to the challenges Japanese researchers face when writing in English. It covers what to include, how to structure it, the language conventions international journals expect, and the most common mistakes that lead to desk rejection. For the broader fundamentals of abstract writing across document types, see our complete guide on how to write an abstract.

Quick Answer: What International Journals Expect

Six required elements. Background, purpose, methodology, results, conclusion, and keywords. All must appear, whether the abstract is structured (with labeled sections) or unstructured (a single paragraph).

Tense conventions matter. Methods and results in past tense. Conclusions in present tense. Japanese tense and aspect work differently from English, which produces predictable errors in Japanese-authored abstracts.

The five highest-stakes mistakes for Japanese researchers. Article errors (Japanese has no articles), passive voice overuse, understated conclusions that read as tentative, missing subjects carried over from Japanese grammar, and overlong background sections. Each can trigger desk rejection before the paper reaches peer review.

The fix isn't politer. Japanese academic culture values modesty in self-presentation. International journals expect clear, confident statements of contribution and implication. Tone calibration is one of the most important revisions Japanese researchers make to their abstracts.

What Is a Journal Abstract and Why Does It Matter?

A journal abstract is a self-contained summary of your entire paper, typically 150 to 300 words, that appears before the introduction. It serves several critical functions simultaneously:

  • Editorial screening. Many journal editors read only the abstract before deciding whether a manuscript is appropriate for their journal and worth sending to peer reviewers. A weak abstract often ends the manuscript's journey at the editor's desk.
  • Peer reviewer orientation. Reviewers read the abstract before reading the full paper. An abstract that clearly signals the research question, methodology, and contribution frames the reviewer's reading of everything that follows.
  • Database indexing and discoverability. Your abstract and keywords are what appear in PubMed, Web of Science, Scopus, and Google Scholar. Researchers who might cite your work will find it through the abstract, or not find it at all.
  • Reader triage. Researchers across your field read abstracts to decide whether a paper is worth reading in full. Your abstract determines whether your work enters the scholarly conversation or remains unread.

Step 1: Understand Your Target Journal's Abstract Requirements

Before writing a single word, read the Instructions for Authors on your target journal's website and identify exactly what it requires for abstracts. Different journals have different specifications. Submitting an abstract that doesn't conform signals to editors that you haven't read the guidelines carefully. That's a poor first impression with any editor.

The key specifications to check are:

  • Word limit. Most journals specify a maximum of 150 to 300 words. Some impose strict limits of 200 or 250 words. The limit is absolute. Exceeding it is grounds for immediate return of the manuscript.
  • Structure. Some journals require an unstructured abstract (a single paragraph). Others require a structured abstract with labeled sections, typically Background, Methods, Results, and Conclusion. Medical and health science journals following ICMJE guidelines almost universally require structured abstracts.
  • Tense. Some journals specify which tense to use in each section. If no guidance is given, follow the standard conventions described below.
  • Person. Most international journals prefer third-person ("The study examined...") over first-person ("We examined..."), though some journals in the sciences now accept or prefer "we." Check your target journal's published abstracts to see what is standard.
  • Keywords. Most journals require a separate list of four to eight keywords following the abstract. These should be terms that researchers in your field would actually use when searching databases, not just the words that appear most frequently in your paper.

Step 2: Know the Six Elements Every Journal Abstract Must Contain

Whether your target journal requires a structured or unstructured abstract, the same core information must be present. International journals expect all six of the following elements:

1. Background and Context

One to two sentences establishing what is already known about your topic and why the gap your research addresses exists. This isn't a literature review. It's the minimum context a reader needs to understand why your study was necessary. Every word counts in a 250-word abstract.

Example: "Financial risk tolerance is a critical determinant of household investment decisions, yet gender differences in the factors that predict risk tolerance have not been fully decomposed in nationally representative samples."

2. Research Purpose or Objective

One sentence stating precisely what your study set out to do. Use a clear statement of purpose: "This study examined...," "The purpose of this research was to...," or "We investigated...." Avoid vague formulations like "This study is about..." or "This paper discusses...." A clear, direct purpose statement signals to editors and reviewers that the research is focused and answerable.

Example: "The purpose of this study was to identify the factors related to financial risk tolerance among men and women using a decomposition technique applied to a nationally representative dataset."

3. Methodology

Two to three sentences describing how the study was conducted. Include the study design, data source or sample, key measures, and analytical approach. For quantitative studies, name the statistical method used. For qualitative studies, name the analytical framework. Reviewers in your field need enough methodological information to assess whether your findings are credible.

Example: "Data were drawn from the 2013 Survey of Consumer Finances, a nationally representative dataset. A full interaction model with repeated-imputation inference techniques was used to decompose gender differences in financial risk tolerance across two outcome categories: high risk tolerance and some risk tolerance."

4. Results

This is the most important part of a journal abstract and the section that receives the most attention from editors and reviewers. State your main findings specifically and concretely. Don't use vague language like "positive results were found" or "the hypothesis was supported." Name what was found. Include key statistics where the journal permits and where space allows.

Example: "Gender differences in financial risk tolerance were explained by gender differences in the individual determinants of risk tolerance rather than by gender itself. Income uncertainty and net worth moderated the relationship between gender and high risk tolerance, with income uncertainty having opposite effects on men and women."

5. Conclusion and Implications

One to two sentences interpreting what your results mean and why they matter. What do your findings contribute to the field? What do they suggest for practice, policy, or future research? A conclusion that merely restates the results without interpreting them is a missed opportunity and a common reason for negative reviewer feedback.

Example: "Financial fiduciaries should understand the differences in income uncertainty and net worth between men and women and how those differences relate to risk tolerance, rather than assuming gender itself is the primary driver of conservative investment behavior."

6. Keywords

List four to eight keywords after the abstract, following the journal's formatting instructions. Choose terms that are specific enough to reach the right audience but broad enough to be searchable. Use controlled vocabulary from your field's standard index where applicable: MeSH for medical research, PsycINFO thesaurus for psychology, JEL codes for economics. Don't simply copy the most frequent words from your title.

Step 3: Choose the Right Structure

Unstructured Abstract (Single Paragraph)

Used by most humanities, social science, and many natural science journals. All six elements appear in a single flowing paragraph. The challenge is making the paragraph coherent and readable while covering all required elements within the word limit. Each sentence must earn its place. There is no room for transitional filler.

Structured Abstract (Labeled Sections)

Required by most medical, health science, and clinical research journals. The six elements above are divided into labeled sections, typically Background (or Introduction or Purpose), Methods, Results, and Conclusions (or Discussion). Some journals add additional sections such as Objective, Participants, or Implications. Always follow the exact section headings your target journal specifies. Don't substitute your own headings.

Step 4: Apply the Correct Tense Conventions

Tense in an English abstract isn't arbitrary. International journals follow specific conventions that Japanese academic writers frequently get wrong because Japanese tense and aspect function differently from English. Here are the rules:

  • Background and context: present tense for what is generally accepted as true ("Risk tolerance influences investment decisions"), past tense for specific prior findings ("Smith (2018) found that...")
  • Purpose statement: past tense ("This study examined...") or present tense if describing a current state ("This paper reports...")
  • Methods: past tense throughout ("Data were collected from 2,246 households. Logistic regression was used to analyze...")
  • Results: past tense throughout ("The results indicated...", "A significant difference was found...")
  • Conclusion and implications: present tense for general claims and interpretations ("These findings suggest that...", "Practitioners should consider...")

The most common tense error in Japanese-authored abstracts is using present tense throughout, including in the methods and results sections. This gives the impression that the study hasn't yet been completed, which raises immediate concerns for editors reviewing the manuscript.

Step 5: Write the Abstract Last

Write the abstract after you have completed the full manuscript. It's much easier to summarize a paper you've already written than to anticipate what a paper will contain. Many Japanese researchers write the abstract first, then struggle to revise it as the paper evolves, and submit an abstract that no longer accurately represents the finished paper.

A practical approach: go through each major section of your completed manuscript and extract one key sentence. Your background section gives you the context sentence. Your introduction gives you the purpose statement. Your methods section gives you the methodological summary. Your results section gives you the key findings. Your discussion or conclusion gives you the implication sentence. Assemble these extracted sentences into a first draft, then revise for coherence, concision, and word count.

Step 6: Check That Your Abstract Can Stand Alone

A journal abstract must be entirely self-contained. Readers encountering your abstract in a database search won't have access to the full paper. Everything they need to understand your study must be present in the abstract itself. This means:

  • Don't refer to figures, tables, or sections of the main paper ("As shown in Figure 3...")
  • Don't use abbreviations that aren't defined within the abstract itself, even if they're defined in the main text
  • Don't include citations. Abstracts do not cite references.
  • Don't use footnotes
  • Don't assume the reader has read your introduction. The abstract must provide its own context.

Common Abstract Mistakes That Lead to Desk Rejection

The following errors appear frequently in abstracts submitted by Japanese researchers and are among the most common reasons for desk rejection or a request for major revision before peer review:

  • Exceeding the word limit. Abstracts that are too long are returned immediately at many journals. Count your words before submitting and cut ruthlessly if necessary.
  • Vague results statements. "The results were positive" or "the hypothesis was supported" tells an editor nothing. State specifically what was found.
  • Missing the conclusion. Many Japanese-authored abstracts end with the results and omit the interpretive conclusion. This reflects Japanese academic conventions that value restraint in self-presentation. International journals expect you to tell them what the results mean, not just what they were.
  • Wrong tense in the methods and results sections. Using present tense for completed work ("Data are collected from...") signals unfamiliarity with international journal conventions.
  • Article errors. Japanese has no articles. Missing or incorrect use of "a," "an," and "the" is the most pervasive language error in Japanese-authored abstracts. Multiple article errors in a 200-word abstract signal to an editor that the English language quality of the full paper may not meet the journal's standards.
  • Subject omission. Japanese permits the subject to be dropped much more freely than Korean, often even at the sentence level when context is clear. English requires an explicit subject in nearly every sentence. Sentences like "Used logistic regression to analyze..." need an explicit subject ("The study used...") in English.
  • Overly long background. Japanese academic writing often builds extensive context before arriving at the research question, reflecting a rhetorical convention that values thorough orientation. An international journal abstract has no space for this. State the context in one sentence and move directly to the research question.
  • Passive voice where active is expected. Japanese academic writing strongly favors passive constructions, which are considered more formal and modest in Japanese. Many international journals, particularly in the sciences, now prefer active voice in abstracts. "The analysis revealed..." is stronger than "It was revealed that..." Check your target journal's published abstracts to see what is standard.
  • Understated conclusions. Japanese academic culture values modesty, which sometimes produces conclusions that are too brief or too cautious for international journal standards. Your conclusion should clearly state what the findings contribute and what practitioners or future researchers should do with them. This is one of the most important calibrations Japanese researchers make to their abstracts when targeting international journals.
  • Poor keyword selection. Keywords that are too broad, too narrow, or simply copied from the title don't serve the discoverability function keywords are meant to serve.

Language Challenges Specific to Japanese-Speaking Researchers

Writing a clear, correctly formatted abstract in English is difficult for any non-native speaker, but Japanese researchers face specific structural challenges that go beyond vocabulary. Japanese and English organize sentences, encode grammatical relationships, and signal formality through fundamentally different mechanisms. The article errors, tense inconsistencies, passive voice patterns, and understated conclusions noted above all have roots in the structural differences between Japanese and English.

Japanese is a Subject-Object-Verb language. English is Subject-Verb-Object. Japanese allows subjects to be dropped when they can be inferred from context. English doesn't. Japanese academic writing strongly favors passive voice as a marker of scholarly formality and modesty. English academic writing has moved significantly toward active voice, particularly in the sciences. And Japanese has no articles, making every article decision in English a conscious choice that native speakers make automatically.

Japanese also marks the topic of a sentence explicitly through the particle "wa," which produces a topic-comment information structure quite different from English's subject-verb-object pattern. When this carries over into English writing, the result is often sentences that delay the main point in ways that international reviewers can find unclear. The modesty norms that produce understated conclusions are even stronger in Japanese academic writing than in Korean, and calibration of confidence in the conclusion is one of the most consequential revisions Japanese researchers make.

Understanding the source of these patterns makes them easier to address systematically.

A Model Abstract: Annotated Example

The following is a published abstract from Fisher and Yao (2017), annotated to show how each element functions:

"The purpose of this research is to explore gender differences in financial risk tolerance using a large, nationally representative dataset, the Survey of Consumer Finances. [ Purpose] The impact of the explanatory variables in the model is allowed to differ between men and women to decompose gender differences in financial risk tolerance. [ Methodology] The results indicate that gender differences in financial risk tolerance are explained by gender differences in the individual determinants of financial risk tolerance, and that the disparity does not result from gender in and of itself. [ Main finding] The individual variables that moderate the relationship between gender and high risk tolerance are income uncertainty and net worth, with income uncertainty moderating the relationship between gender and some risk tolerance. [ Specific results] Financial fiduciaries should understand the differences in income uncertainty and net worth between men and women and how those differences relate to risk tolerance." [ Conclusion and implications]

Notice what this abstract does well: the purpose is stated in the first sentence, the methodology is described concisely without technical jargon, the results are specific rather than vague, and the conclusion tells practitioners exactly what to do with the findings. The background context is embedded implicitly rather than stated in a separate sentence, a space-saving technique appropriate when the research context is well-established in the field.

A Checklist Before You Submit

Before submitting your abstract with your manuscript, work through this checklist:

  • Is the word count within the journal's specified limit?
  • Does the abstract include all six required elements: background, purpose, methods, results, conclusion, and keywords?
  • Is the abstract formatted as the journal requires (structured or unstructured)?
  • Are the methods and results sections written in past tense?
  • Is the conclusion written in present tense?
  • Are all articles ("a," "an," "the") used correctly throughout?
  • Are all nouns treated as countable or uncountable as English grammar requires?
  • Are subjects explicit in every sentence?
  • Does the abstract stand alone without reference to figures, tables, or sections of the main paper?
  • Are abbreviations defined within the abstract itself?
  • Are the keywords specific enough to reach your target audience in database searches?
  • Does the conclusion state your findings' contribution and implications clearly and specifically?
  • Has the abstract been read by a native English speaker?

Professional English Editing for Japanese Researchers

Even a technically strong abstract can be desk-rejected if the English language quality doesn't meet the standards of an international journal. Article errors, tense inconsistencies, passive voice overuse, and awkward sentence constructions are all visible in an abstract of 200 words, and editors notice them immediately. These aren't signs of insufficient effort. They're predictable consequences of writing across two of the world's most structurally different language pairs.

Frequently Asked Questions

How long should a journal abstract be?

Most international journals require abstracts of 150 to 300 words, with some imposing strict limits of 200 or 250 words. The limit is absolute. Exceeding it is grounds for immediate return of the manuscript without peer review at many journals. Always check the specific word limit on your target journal's Instructions for Authors page before drafting. Many Japanese researchers find their first draft is significantly over the limit because Japanese academic writing tends to build extensive background context before arriving at the research question. Cutting that context is one of the first revisions most abstracts need.

What is the difference between a structured and unstructured abstract?

An unstructured abstract presents all six required elements (background, purpose, methods, results, conclusion, keywords) in a single flowing paragraph. Most humanities, social science, and many natural science journals use this format. A structured abstract divides the same elements into labeled sections, typically Background, Methods, Results, and Conclusions. Medical and health science journals following ICMJE guidelines almost universally require structured abstracts. The information is the same in both formats. Only the visual organization differs. Always check your target journal's instructions to know which format to use.

What tense should I use in a journal abstract?

Tense in an English journal abstract follows specific conventions. Background and general claims use present tense ("Risk tolerance influences investment decisions"). Specific prior findings use past tense ("Smith (2018) found that..."). The purpose statement uses past tense ("This study examined..."). Methods use past tense throughout ("Data were collected from..."). Results use past tense ("The results indicated..."). Conclusions and implications use present tense ("These findings suggest that..."). The most common tense error in Japanese-authored abstracts is using present tense throughout, including in the methods and results sections, which gives the impression that the study hasn't yet been completed.

What are the most common abstract mistakes Japanese researchers make?

The most common abstract mistakes in Japanese-authored manuscripts include article errors (Japanese has no articles), passive voice overuse where international journals expect active voice, understated conclusions that read as tentative or uncertain, subject omission carried over from Japanese grammar, overlong background sections that exceed the word limit, wrong tense in methods and results sections, and vague results statements that fail to name specific findings. All of these have roots in the structural and cultural differences between Japanese and English academic writing. Understanding the source of the patterns makes them easier to address systematically.

Should I use active or passive voice in my abstract?

Most international journals now prefer active voice in abstracts, particularly in the sciences. Japanese academic writing traditionally favors passive constructions as markers of scholarly formality and modesty, which produces a noticeable difference when Japanese researchers write English abstracts. "The analysis revealed three patterns" is stronger than "Three patterns were revealed." Check your target journal's published abstracts to see what is standard. When in doubt, prefer active voice where it doesn't compromise meaning, but follow the journal's published norms when they're clearly established.

Do journal abstracts include citations?

No. Journal abstracts don't include citations or references. The abstract must be entirely self-contained. Readers encountering your abstract in a database search won't have access to the full paper, so everything they need to understand your study must be present in the abstract itself. If a point requires a citation, it probably belongs in the introduction or discussion of the main paper, not in the abstract. The same principle applies to figures and tables: the abstract shouldn't refer to anything outside itself.

How many keywords should an abstract have?

Most international journals require four to eight keywords following the abstract. The exact number varies by journal, so check the Instructions for Authors before drafting. Choose terms that researchers in your field would actually use when searching databases. Use controlled vocabulary from your field's standard index where applicable: MeSH for medical research, PsycINFO thesaurus for psychology, JEL codes for economics. Don't simply copy the most frequent words from your title. Strong keyword selection improves the discoverability of your work in databases like PubMed, Web of Science, Scopus, and Google Scholar.

How can Japanese researchers improve their abstract's English?

Improving abstract English begins with understanding the structural differences between Japanese and English. Article use, tense conventions, subject expression, active versus passive voice, and conclusion confidence all function differently in the two languages, which produces predictable error patterns in Japanese-authored abstracts. Reading published abstracts from your target journal helps internalize the conventions of your field. Having a native English speaker review the abstract before submission catches errors that may be invisible to the writer. Professional editing services that specialize in working with Japanese researchers can also identify and correct the systematic patterns that come from writing across two structurally different language pairs.
