学術的な読む・書くAcademic Reading and Writing
Chapter Objectives
By the end of this chapter, you will be able to:
- Recognize the structural conventions of Japanese academic prose, including abstracts, literature reviews, and discussion sections.
- Use core academic phrase frames such as 本稿では, 先行研究, and 示唆する to frame a paper's purpose, situate it within prior work, and state its implications.
- Read a short academic-style abstract and identify its research question, method, and stated contribution.
- Summarize a source's claim in your own words while distinguishing your voice from the source's voice.
- Write a short academic-style paragraph that states a claim, supports it with reasoning, and acknowledges a limitation.
- Apply basic keigo appropriately within an academic register, distinguishing it from the ceremonial keigo of Chapter 6.
- Listen to a short excerpt resembling an academic presentation and identify its main claim and supporting point.
- Avoid common errors such as overclaiming, uncritical citation, and mixing academic register with casual phrasing.
Communication Scenario
Encouraged by her growing comfort with institutional Japanese, Emma enrolls in a evening seminar at a local university extension program, where she is auditing a course on regional language policy. Her instructor, 中村先生, asks the auditing students to read a short abstract on dialect attrition, summarize its argument, and draft a short response paragraph situating their own view within the existing research. Emma quickly finds that academic Japanese has its own conventions: a paper opens by stating what it will do, situates itself against 先行研究, and closes by carefully hedging its conclusions rather than overstating them. 中村先生 reminds the class that summarizing a source accurately, without either copying its wording or distorting its claim, is itself a skill that takes practice.
- The learner studies core vocabulary for abstracts, literature reviews, methodology, and discussion.
- The learner studies academic phrase frames for framing purpose, citing prior work, and stating implications.
- The learner reads a model abstract and a model discussion excerpt.
- The learner listens to an excerpt resembling a short academic presentation.
- The learner writes a short paragraph summarizing a source and responding to it.
- The learner completes a performance task combining reading, listening, and academic writing.
Core Vocabulary
This chapter's vocabulary supports abstracts, literature reviews, research summaries, methodology, results, and discussion. All items are drawn from academic written registers and are intended for recognition and, where marked productive, for controlled production in reading summaries and short academic paragraphs.
| Japanese | Reading | Meaning | Status |
|---|---|---|---|
| 本稿 | ほんこう | this paper, this article (self-referential academic term) | Productive |
| 先行研究 | せんこうけんきゅう | prior research, previous studies | Productive |
| 示唆する | しさする | to suggest, to imply (of findings or evidence) | Productive |
| 要旨 | ようし | abstract, summary of a paper | Productive |
| 調査対象 | ちょうさたいしょう | research subject, object of investigation | Productive |
| 分析結果 | ぶんせきけっか | results of analysis | Productive |
| 考察 | こうさつ | discussion, critical consideration | Productive |
| 課題 | かだい | issue, remaining problem for future work | Productive |
| ～と考えられる | ～とかんがえられる | it can be considered that ~ (hedged academic claim) | Productive |
| 今後の課題 | こんごのかだい | issues for future research | Productive |
| 妥当性 | だとうせい | validity, appropriateness (of a method or claim) | Receptive |
| 既存の研究 | きぞんのけんきゅう | existing research (variant of 先行研究) | Receptive |
| 論旨 | ろんし | the main line of an argument | Receptive |
Items marked Receptive appear in the reading materials below but are not required for independent production in this chapter's performance task.
れんしゅう — Practice: Sort the vocabulary above into three groups: (1) words used mainly to frame a paper's purpose, (2) words used mainly to describe method or results, and (3) words used mainly in discussion or limitations. Be ready to explain any item that fits more than one group.
Script and Typography Focus
This chapter's script focus is academic kanji and terminology, together with citation-like formatting conventions and the verification of names and titles referenced in scholarly writing. Academic Japanese typically writes technical compounds fully in kanji rather than mixing in katakana or hiragana substitutes, and it generally carries little or no furigana, since the assumed reader has advanced literacy.
Academic Japanese frequently references authors, institutions, and prior studies by name. Because kanji readings of personal and institutional names cannot be reliably guessed from the characters alone, never invent or assume a reading for a scholar's name or a research institution. When a name matters for a task, treat it the same way you would treat any other unscheduled or unverified reading: flag it for confirmation rather than guessing.
れんしゅう — Practice: Before reading the Model Abstract below, predict which vocabulary items are likely to appear entirely in kanji without furigana, and compare your prediction against the passage.
Pronunciation Focus
Academic Japanese sentences are often long and heavily nominalized, so reading them aloud clearly requires locating the natural internal pause points, typically after a topic phrase marked by は or before a clause-final conjunction such as が or ため. Practice reading a long academic sentence by first marking where you would pause if explaining its content conversationally, then reading it aloud at a measured pace with accurate mora timing and vowel length, even through dense compounds like 分析結果.
Grammar and Sentence Patterns
This chapter authorizes academic phrase frames for stating a paper's purpose, situating it against prior research, and stating implications and limitations, together with continued basic keigo appropriate to an academic register.
1. Framing purpose with 本稿では
Purpose: to state clearly, near the opening of a paper or paragraph, what the piece of writing itself will do.
- 本稿では、地方における言語政策の変化を検討する。This paper examines changes in regional language policy.本稿では + object + 検討する
- 本稿の目的は、若年層の方言意識を明らかにすることである。The purpose of this paper is to clarify young people's awareness of dialect.本稿の目的は～ことである (nominalized purpose statement)
2. Situating a paper against 先行研究
Purpose: to connect the current discussion to existing research, showing what is already known and what remains open.
- 先行研究では、世代による意識の違いが繰り返し示されてきた。Prior research has repeatedly shown differences in awareness by generation.先行研究では + 示されてきた (passive, ongoing)
- しかし、先行研究の多くは都市部を対象としており、地方の実態は十分に明らかではない。However, much prior research has focused on urban areas, and the actual situation in regional areas is not sufficiently clear.しかし + 先行研究の多くは (contrast, gap in the literature)
3. Stating implications with 示唆する and hedged claims
Purpose: to present a finding's implication carefully, without overstating what the evidence supports.
| Function | Formula | Notes |
|---|---|---|
| Stating an implication | この結果は、～ことを示唆している | frames a finding as suggestive rather than conclusive |
| Hedging a claim | ～と考えられる | softer than ～である; signals reasoned inference |
| Acknowledging a limitation | 今後の課題として、～が挙げられる | names an open issue for future research |
| Closing a discussion | 以上のことから、～と言える | draws a summary conclusion from the preceding discussion |
- この結果は、地域による方言意識の差が拡大している可能性を示唆している。This result suggests the possibility that regional differences in dialect awareness are widening.示唆している (hedged, possibility-marked implication)
- 調査対象が限られているため、今後の課題として、より広い地域での調査が挙げられる。Because the research subjects were limited, a broader regional survey can be named as an issue for future research.今後の課題として + 挙げられる (naming a limitation)
Academic Japanese writing consistently favors hedged, cautious claims such as ～と考えられる or ～可能性がある over flat assertions such as ～である alone. This is not a sign of a weak argument; it is the expected convention for presenting evidence-based reasoning responsibly. A learner who writes only unhedged, absolute claims will sound overconfident rather than more authoritative.
Grammar Practice
- Write an opening sentence using 本稿では to introduce a short paper about generational differences in keigo use.
- Write a sentence using 先行研究では to summarize a general finding, then add a contrasting sentence identifying a gap in that research.
- Rewrite the unhedged sentence 若い世代は敬語をあまり使わない。 using ～と考えられる to soften the claim appropriately.
- Identify which of the four formulas in the table above would be most appropriate for the closing sentence of a short discussion section, and explain why.
Model Dialogue
Setting: 中村先生 and Emma discuss her draft summary of the assigned abstract during office hours. Academic register, instructor-student relationship, continued basic keigo.
Emma revises her draft, underlining every hedged claim in one color and every reference to prior research in another.
ないようりかい — Comprehension check: What weakness does 中村先生 first identify in Emma's summary? What phrase does Emma use to hedge her final claim, and why does 中村先生 praise it?
Guided Practice
タスク１ — Frame identification. Take the Model Abstract in the Reading Practice section below and underline every instance of a purpose frame, a prior-research frame, and a hedged claim, labeling each.
タスク２ — Formula assembly. Using the table of formulas above, write a four-sentence mini-discussion: one sentence stating purpose, one citing prior research, one stating an implication, and one naming a limitation.
タスク３ — Hedge check. Review your four sentences from タスク２ and confirm that no claim is stated more strongly than the evidence you described would support.
Listening Practice
Ask your instructor, a partner, or a text-to-speech tool to read the following short passage aloud.
きくタスク — An excerpt from a short academic presentation
本発表では、地方における方言使用の実態について報告する。先行研究では、都市部を中心に方言使用の減少が指摘されてきたが、地方の実態は十分に検討されていない。今回の調査結果は、地方でも若年層を中心に方言使用が減少している可能性を示唆している。今後の課題として、より長期的な調査が必要であると考えられる。
聞くタスク — Listening task: Listen at least twice. (1) What does the presenter say this presentation will report on? (2) What gap in prior research does the presenter identify? (3) What does the presenter say the results suggest? (4) What does the presenter name as an issue for future research?
Speaking Practice
コントロールされた練習 — Controlled practice: Purpose or prior research?
- Given a short sentence, identify aloud whether it functions as a purpose statement, a reference to prior research, or a hedged implication.
- Given a plain, unhedged claim, restate it aloud using an appropriate hedging formula.
- Given a research topic, produce aloud a one-sentence purpose statement using 本稿では.
コミュニケーションタスク — Presenting a short research summary
Using the Listening Practice excerpt as a model, deliver aloud a short spoken summary of a topic of your choice, including a purpose statement, a reference to existing understanding of the topic, and one hedged implication.
ひとりでもできる練習 — Solo practice: Reading the academic excerpt aloud
Read the Listening Practice passage aloud, locating natural pause points within its longer sentences and maintaining measured, clear delivery. Record yourself and check whether your pacing makes the argument easy to follow.
Reading Practice
Read the model abstract below, drawn from the assignment Emma is working on with 中村先生, and complete the questions that follow.
要旨（抜粋）— Model Abstract (excerpt)
本稿では、地方における方言使用の世代差について論じる。先行研究では、都市部での方言使用の減少が指摘されてきたが、地方における実態は十分に明らかではない。本調査では、調査対象を地方の三世代の話者とし、日常会話における方言使用を分析した。分析結果は、若年層において方言使用が減少している可能性を示唆している。ただし、調査対象が限られているため、今後の課題として、より広い地域での長期的な調査が挙げられる。
- Identify the sentence that states the purpose of the paper, and name the frame it uses.
- Identify the sentence that references prior research, and explain what gap it identifies.
- Identify the sentence that states the paper's main implication, and name the hedging expression it uses.
- Identify the sentence that names a limitation, and explain why the author includes it rather than omitting it.
Writing Workshop
Draft a short academic-style paragraph summarizing a source and responding to it, applying the purpose, prior-research, and hedging frames from this chapter.
- Choose a topic. Select a short claim about language, education, or community life that you can plausibly discuss, real or invented for practice.
- Open with a purpose statement. Use 本稿では or an equivalent frame to state what your paragraph will do.
- Reference existing understanding. Use a construction such as 先行研究では～とされている to situate your topic.
- State one hedged implication using ～と考えられる or ～ことを示唆している.
- Name one limitation using 今後の課題として～が挙げられる.
- Write a one-sentence note in Japanese identifying which sentence in your paragraph is the most strongly hedged, and why you hedged it that way.
チェックリスト — Revision checklist:
- The paragraph opens with a clear purpose statement.
- At least one sentence references prior research or existing understanding.
- No claim is stated more strongly than the evidence described would support.
- At least one limitation is named rather than omitted.
- Kanji and terminology are used consistently, with furigana reserved only for genuinely rare or unscheduled readings.
Culture and Communication
Japanese academic writing places strong value on careful, hedged claims and explicit acknowledgment of a study's limitations, reflecting a broader convention in which overstating one's findings is viewed as a lapse in scholarly responsibility rather than a sign of weak confidence. A paper that includes a clear 今後の課題 section is generally read as more credible, not less, because it signals that the author understands the boundaries of the evidence presented.
Academic writing conventions in Japanese remain broadly consistent across universities and research institutions nationwide, since scholarly publishing follows shared disciplinary norms rather than regional speech patterns. Where variation does appear, it is more likely to concern discipline-specific terminology or house style guidelines from a particular journal or institution than regional dialect.
Common Mistakes to Avoid
Error: Writing a flat, unhedged conclusion such as 若い世代は方言を使わない。 based on a small or limited study.
Correction: Use a hedging formula appropriate to the strength of the evidence: 若い世代において方言使用が減少している可能性があると考えられる。
Error: Reproducing a source's sentence nearly word-for-word and presenting it as one's own summary, without restating the claim in different phrasing.
Correction: Restate the source's claim in your own words and, where relevant, attribute it explicitly with a frame such as 先行研究では～とされている, rather than echoing the original sentence structure.
Error: Combining an academic frame such as 本稿では with a casual predicate ending such as ～と思う or ～だと思います in the same paragraph.
Correction: Keep academic register consistent throughout a paragraph, preferring forms such as ～と考えられる or ～と言える over conversational hedges like ～と思う.

Answer Key
Core Vocabulary — Sorting practice
Open-ended; representative grouping: (1) purpose framing — 本稿, 要旨; (2) method/results — 調査対象, 分析結果, 先行研究; (3) discussion/limitations — 考察, 課題, ～と考えられる, 今後の課題. Some items, such as 先行研究, plausibly belong to more than one group.
Script and Typography Focus
Open-ended prediction task; confirm against the Model Abstract, which presents terms such as 分析結果 and 調査対象 entirely in kanji without furigana.
Grammar Practice
(1) Open-ended; model: 本稿では、世代による敬語使用の違いについて論じる。 (2) Open-ended; model: 先行研究では、若年層の敬語使用の減少が指摘されている。しかし、地方における実態は十分に検討されていない。 (3) 若い世代は敬語をあまり使わないと考えられる。 (4) The closing formula 以上のことから、～と言える is generally most appropriate for a closing sentence, since it draws a summary conclusion from the discussion that precedes it.
Model Dialogue — Comprehension Check
中村先生 first identifies that Emma's opening sentence is too weak and suggests using 本稿では. Emma hedges her final claim with ～と考えられます, and 中村先生 praises this because it avoids the overstatement of a flat claim like 新しいです.
Listening Practice — Model answers
(1) The presentation reports on the actual situation of dialect use in regional areas. (2) Prior research has focused mainly on urban areas, leaving the regional situation insufficiently examined. (3) The results suggest that dialect use may be declining among younger speakers even in regional areas. (4) The presenter names a longer-term study as an issue for future research.
Reading Practice
(1) 本稿では、地方における方言使用の世代差について論じる states the purpose, using the 本稿では frame. (2) 先行研究では、都市部での方言使用の減少が指摘されてきたが、地方における実態は十分に明らかではない references prior research and identifies the gap concerning regional areas. (3) 分析結果は、若年層において方言使用が減少している可能性を示唆している states the main implication, hedged with 可能性を示唆している. (4) 今後の課題として、より広い地域での長期的な調査が挙げられる names the limitation; the author includes it to responsibly acknowledge the boundaries of a study with limited research subjects.

Looking Ahead
いまできること — What you can do now
You can frame a paper's purpose, situate a discussion against prior research, state hedged implications, and name limitations using recognized academic phrase frames, while maintaining consistent academic register and continued basic keigo. This foundation in academic reading and writing carries forward into Chapter 8, where these same systems support high-level professional domain communication.
