最終プロジェクト：高度な日本語運用Final C1 Project: Integrated Advanced Communication
Chapter Objectives
By the end of this chapter, you will be able to:
- Carry a Chapter 19 project proposal through to a complete, multi-source, publication-ready piece of Japanese writing.
- Conduct and report on a short interview using operational keigo appropriate to a professional relationship.
- Compare findings across at least two sources and explain agreement, disagreement, and unresolved questions between them.
- Deliver a formal oral presentation of the project and respond to unscripted questions.
- Produce an audience-adapted mediation of the project's findings for a general readership.
- Apply the full editing and revision process from Chapter 18 to a final draft before publication.
- Reflect in Japanese on which language systems from this volume were most useful to the project and why.
- Demonstrate integrated control of Volume IV's grammar, register, vocabulary, and script systems across listening, speaking, reading, and writing.
Communication Scenario
山本さん has approved Emma's one-page proposal from Chapter 19: a feature on the role of regional dialect in workplaces that are becoming more multilingual, built on an interview with a local company and two survey reports whose methods do not fully match. Over the next two weeks, Emma must resolve her open questions, conduct the interview in appropriately formal Japanese, compare her three sources honestly, draft the full feature, adapt a version for the magazine's general readership, revise everything against the Chapter 18 checklist, and present the finished project to 山本さん and a small editorial team — fielding their questions on the spot. This chapter follows Emma through each stage and asks the learner to complete a parallel project of their own choosing.
- The learner listens to Emma's interview with a workplace representative and to a short editorial-meeting exchange about the findings.
- The learner reads Emma's completed feature article and its general-audience companion summary.
- The learner conducts, records, or scripts a short interview of their own related to their project topic.
- The learner writes a complete, multi-source, source-attributed feature article and a general-audience adaptation.
- The learner delivers a formal presentation of their project and responds to questions from a partner or instructor.
- The learner reflects in writing on which grammar, vocabulary, register, and script systems from Volume IV were most central to completing the project.
Core Vocabulary
This chapter does not introduce a new vocabulary domain of its own. Instead, it activates and recombines vocabulary from across Volume IV — explanation and abstraction (Chapters 2–5), keigo and meetings (Chapters 6–10), literary style, media, and mediation (Chapters 11–15), and specialized fields, research, and revision (Chapters 16–19). The twelve items below support the interview, comparison, and presentation stages of the capstone project specifically.
| Japanese | Reading | Meaning | Domain |
|---|---|---|---|
| 取材する | しゅざいする | to gather material, to report on/interview for a story | Research |
| 聞き取り調査 | ききとりちょうさ | interview-based survey | Research |
| 一致する | いっちする | to agree, to match (of findings) | Comparison |
| 食い違う | くいちがう | to diverge, to be inconsistent | Comparison |
| 結論づける | けつろんづける | to conclude, to draw a conclusion | Argument |
| 質疑応答 | しつぎおうとう | question-and-answer session | Presentation |
| その場で答える | そのばでこたえる | to answer on the spot | Presentation |
| 振り返る | ふりかえる | to look back on, to reflect | Reflection |
| 総合的に | そうごうてきに | comprehensively, taking everything together | Synthesis |
| 掲載する | けいさいする | to publish, to run (an article) | Publication |
| 読み応えがある | よみごたえがある | to be substantial/rewarding to read | Evaluation |
| 今後の課題 | こんごのかだい | a task/question for the future | Reflection |
All twelve items are productive for this chapter. The project itself should draw actively on vocabulary already made productive in Chapters 2 through 19; no unscheduled domain vocabulary should be required to complete it.
れんしゅう — Practice: For each of the twelve items above, name one earlier chapter in this volume whose vocabulary or grammar it would naturally combine with in a finished project (for example, 結論づける with Chapter 3's 以上のことから).
Script and Terminology Focus
This chapter assesses advanced kanji recognition and production, specialized terminology from the learner's chosen field, document formatting, and Japanese digital typography, rather than introducing new characters. No new kanji are activated in Chapter 20.
A finished feature article should follow the same furigana and typography conventions established across Chapters 17 through 19: kanji consolidated earlier in the volume carry no furigana, new or rare readings receive furigana at first mention only, and headings never contain an unglossed reading a target reader could not recover. When two versions of the same piece exist — a specialist feature and a general-audience summary, as in Chapter 19 — each version's furigana, terminology, and heading length should be checked separately, since a single formatting pass is not sufficient for two different readerships.
れんしゅう — Practice: Before submitting your final project, list every kanji compound in your draft that is specific to your project's field (not general-purpose Volume IV vocabulary), and confirm that each one carries furigana on first mention only if it is genuinely rare or unscheduled.
Pronunciation Focus
A formal presentation followed by a question-and-answer session places different demands on delivery than reading a prepared script. During the prepared portion, maintain steady phrase-level pitch and clear sentence-final falls to mark completed points, as practiced since Chapter 9. During 質疑応答, a brief pause before answering — rather than an immediate rushed response — is both a natural processing strategy and a mark of a considered answer; it does not need to be filled with hesitation sounds. Keep mora timing, vowel length, and moraic ん steady under the added pressure of unscripted speech, and treat any pitch-accent notation you consult while preparing as a reference tool, not a required marking.
Grammar and Sentence Patterns
This chapter authorizes the integration of every major system activated across Volume IV: advanced explanation and abstraction (Ch. 2), logic and organization (Ch. 3), source reading and attribution (Ch. 4), operational keigo (Ch. 6), meeting and negotiation language (Ch. 7), formal written style (Ch. 8), presentation and Q&A structures (Ch. 9), literary and media interpretation (Ch. 11–12), mediation and audience adaptation (Ch. 13, 19), labeled variation (Ch. 14), specialized domain discourse (Ch. 16), research language (Ch. 17), and revision operations (Ch. 18). No single new grammar point is introduced; the four patterns below specifically support comparing sources and closing out the project.
1. Reporting agreement and divergence: 〜と一致する / 〜と食い違う
Purpose: to state precisely how two or more sources relate to each other, extending Chapter 4's attribution language.
- 田中さんの話は、調査報告書Aの結果とおおむね一致している。What Tanaka-san said largely agrees with the findings of Survey Report A.〜と一致する — stating agreement between sources
- しかし、調査報告書Bの数字は、報告書Aと食い違う部分がある。However, some of Report B's figures diverge from Report A.〜と食い違う — naming a specific divergence
2. Drawing a conclusion from combined evidence: 〜ことから、〜と結論づけられる
Purpose: to move from compared evidence to a stated conclusion, connecting Chapter 3's logical connectors to Chapter 17's research language.
- 三つの資料を総合的に見ると、若い世代の方言使用は減少しているが、職場では見直されつつあることから、単純な衰退とは結論づけられない。Taking all three sources together, dialect use among younger people is declining, but since it is being reconsidered in workplaces, it cannot simply be concluded to be in decline.〜ことから、〜と結論づけられる — evidence-based conclusion with appropriate caution
3. Naming a remaining question: 今後の課題として〜が挙げられる
Purpose: to close a project honestly by naming what remains unresolved, extending Chapter 19's 未解決の点.
- 今後の課題として、より広い地域を対象とした調査の必要性が挙げられる。As a task for the future, there is a need for research covering a wider range of regions.今後の課題として〜が挙げられる — closing with a forward-looking open question
4. Reflecting on the process: 〜を振り返ると
Purpose: to look back on the project and identify which language systems were most useful, supporting the chapter's reflection task.
- 今回のプロジェクトを振り返ると、資料を比較する表現と、敬語を使ったインタビューが特に役に立った。Looking back on this project, the expressions for comparing sources and the keigo I used in the interview were especially useful.〜を振り返ると — reflective framing
Combining Volume IV's systems into one project does not mean using every pattern from every chapter in a single paragraph. A strong capstone project chooses the right tool for each moment: keigo for the interview itself, attribution language when reporting what sources said, comparison language when sources disagree, and plain analytical prose when drawing conclusions. Judging which system belongs where is itself part of C1 control, and it is exactly what the final performance task assesses.
Grammar Practice
- Write a sentence stating that two sources agree, using 〜と一致する.
- Write a sentence naming a divergence between two sources, using 〜と食い違う.
- Write a sentence drawing a cautious conclusion from combined evidence, using 〜ことから、〜と結論づけられる.
- Write a sentence naming an open question for future work, using 今後の課題として〜が挙げられる.
- Write a sentence reflecting on your own project, using 〜を振り返ると.
Model Dialogue
Setting: Emma presents her finished project to 山本さん and a colleague, 佐藤さん, in a small editorial meeting. Formal polite style, with operational keigo appropriate to presenting work to superiors.
山本さん approves the article for publication. Emma's project — interview, source comparison, feature article, general-audience summary, and honest reflection — is now complete.
ないようりかい — Comprehension check: On which point do Emma's interview and Report A agree? Why does Report B diverge, according to Emma? What does Emma name as a task for the future?
Guided Practice
タスク１ — Information extraction. Reread the Model Dialogue and list, in your own words, each of the four project components Emma presents: interview findings, agreement with a source, divergence from a source, and conclusion with an open question.
タスク２ — Sentence building. Using your own project topic, write one original sentence for each of the four components in Task 1, following the grammar patterns from this chapter.
タスク３ — Role reversal. With a partner, take the role of 佐藤さん or 山本さん and prepare two follow-up questions you would ask about a classmate's project, based on the kinds of questions asked in the Model Dialogue.
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 — A short excerpt from Emma's interview with 田中さん
当社では、標準語を基本としながらも、会議の後など、少し打ち解けた場面では方言を使うことがあります。特に、外国から来た社員が増えてから、方言を使うことで、かえって親しみやすい雰囲気が生まれると感じています。もちろん、方言だけでは意味が伝わらないこともあるので、状況によって使い分けることが大切だと思います。
聞くタスク — Listening task: Listen at least twice. (1) In what kind of situation does Tanaka-san's company use dialect? (2) What change is connected to the increased use of dialect, according to Tanaka-san? (3) What caution does Tanaka-san add at the end?
Speaking Practice
コントロールされた練習 — Controlled practice: Pattern drill
- ＿＿＿＿＿は＿＿＿＿＿と一致しています。 (state agreement between two sources)
- しかし、＿＿＿＿＿とは食い違う部分があります。 (name a divergence)
- ＿＿＿＿＿ことから、＿＿＿＿＿と結論づけられます。 (draw a conclusion)
- 今後の課題としては＿＿＿＿＿が挙げられます。 (name an open question)
コミュニケーションタスク — Final capstone presentation
Deliver a five-to-seven-minute formal presentation of your project to a partner or instructor, covering your interview or primary source, your comparison of at least two sources, your conclusion, and one open question for future work. Your listener should ask at least three unscripted questions afterward, and you should respond using this chapter's and earlier chapters' patterns.
ひとりでもできる練習 — Solo practice: Recording your reflection
Record a two-minute spoken reflection on your project using 〜を振り返ると, naming at least three specific language systems from Volume IV that you relied on and explaining briefly why each one mattered.
Reading Practice
Read the closing paragraphs of Emma's finished feature article below and complete the questions that follow.
くらしと専門知識：多言語化する職場と方言の役割（抜粋）
今回の取材と二つの調査報告書を総合的に見ると、方言の使用そのものは若い世代を中心に減少していることが分かる。しかし、田中さんへの聞き取り調査からは、多言語化が進む職場という新しい文脈の中で、方言が果たす役割が見直されつつあることも見えてきた。この点は、単純な「方言の衰退」という結論だけでは説明できない。もちろん、調査報告書Aと報告書Bでは調査方法が異なり、数字の細かい部分では食い違う点もあることを、ここで正直に述べておきたい。今後の課題としては、より広い地域と、より多様な業種を対象とした調査の必要性が挙げられる。
- What three sources does this closing section draw on together?
- What single-cause conclusion does the article explicitly reject, and why?
- What honest limitation does the author name regarding the two survey reports?
- What does the author identify as a task for future research?
Writing Workshop
Complete your capstone project by producing all of the following, drawing on your Chapter 19 proposal and any interview or source material you have gathered.
- Conduct or script an interview related to your project topic, using appropriate keigo, and summarize its key findings in a few sentences.
- Compare your sources explicitly, naming at least one point of agreement using 〜と一致する and at least one point of divergence using 〜と食い違う.
- Draft a complete feature article of at least 500 words in Japanese, integrating your interview, your source comparison, and a conclusion that uses 〜ことから、〜と結論づけられる.
- Name at least one task for future work using 今後の課題として〜が挙げられる.
- Adapt your article into a shorter, general-audience summary with its own headline, following Chapter 19's adaptation principles.
- Revise both pieces using the full Chapter 18 editing checklist and the Chapter 19 pre-publication checklist.
- Write a short reflection of at least 150 words using 〜を振り返ると, naming the Volume IV systems most central to your project.
チェックリスト — Final capstone checklist:
- My project includes at least two distinct sources that are explicitly compared.
- My conclusion is supported by evidence and avoids overclaiming.
- I have named at least one honest, unresolved point for future work.
- My general-audience summary rephrases technical terms without losing accuracy.
- Both pieces have been checked against the Chapter 18 and Chapter 19 checklists.
- My reflection names specific language systems and explains their role in the project.
Culture and Communication
Presenting completed work to colleagues or supervisors in a Japanese professional or academic setting, as Emma does in the Model Dialogue, commonly involves acknowledging limitations and unresolved points directly, rather than presenting the work as flawless. A presenter who names an honest limitation, as Emma does regarding the two survey reports' differing methods, is generally seen as more credible than one who avoids the subject, echoing the proposal-stage norm introduced in Chapter 19.
Emma's finished project returns to the regional and social variation discussed in Chapter 14: her interview subject describes dialect use as something actively chosen for effect in certain workplace situations, rather than as a fixed marker of where someone is from. A capstone project that treats variation this way — as a resource speakers draw on deliberately — reflects the volume's broader caution against treating standard Japanese as neutral and regional Japanese as marked.
Common Mistakes to Avoid
Error: Trying to include at least one example of every grammar pattern from Chapters 1 through 19 in the final project, regardless of whether it fits naturally.
Correction: Choose the systems that genuinely serve the project's content and audience, and let some chapters' patterns appear only lightly or not at all: この記事では、資料比較と結論の表現を特に活用した。
Error: Quietly dropping a source, or softening a real divergence between sources, to make the project's conclusion appear cleaner than the evidence supports.
Correction: Name the divergence directly and explain why it exists, as part of the project's credibility: 二つの報告書は調査方法が異なるため、数字が食い違っている。
Error: Writing a brief, generic reflection such as "this chapter was useful" without naming specific systems or explaining their role.
Correction: Name specific patterns and explain concretely how each one shaped the finished project: 敬語を使ったインタビューがなければ、田中さんから率直な話を引き出せなかったと思う。

Answer Key
Core Vocabulary
Open-ended; check that the learner links each item to a plausible earlier chapter (for example, 聞き取り調査 with Chapter 17's research vocabulary, 質疑応答 with Chapter 9's presentation vocabulary).
Script and Terminology Focus
Open-ended; check that furigana is applied only to genuinely rare or unscheduled readings specific to the learner's own project field.
Grammar Practice
Open-ended; model answers: (1) インタビューの内容は、調査報告書の結果と一致しています。 (2) しかし、報告書Bとは食い違う部分があります。 (3) 三つの資料を比較したことから、単純な結論は出せないと結論づけられます。 (4) 今後の課題としては、より多くの事例を集めることが挙げられます。 (5) このプロジェクトを振り返ると、資料を比較する表現が特に役に立ちました。
Model Dialogue — Comprehension Check
Emma's interview and Report A agree that dialect softens the workplace atmosphere. Report B diverges because it used a different research method, producing more negative figures on younger generations' dialect use. Emma names the need for research covering a wider range of regions as a task for the future.
Guided Practice
Open-ended; evaluate against the Model Dialogue's four components: interview findings, agreement with a source, divergence from a source, and conclusion with an open question.
Listening Practice — Model answers
(1) In somewhat relaxed situations, such as after meetings. (2) An increase in employees from other countries is connected to dialect use creating a more approachable atmosphere. (3) Tanaka-san cautions that dialect alone does not always convey meaning, so it must be used appropriately depending on the situation.
Reading Practice
(1) The interview with Tanaka-san, Survey Report A, and Survey Report B. (2) The article rejects a simple "decline of dialect" conclusion, because the workplace context shows dialect's role being reconsidered rather than only disappearing. (3) The two reports used different research methods, producing some conflicting figures. (4) Research covering a wider range of regions and a more diverse range of industries.
Chapter Review — Sections A through D
Open-ended; check against the Core Vocabulary, Script and Terminology Focus, Grammar Practice, and Reading Practice sections above.
Chapter Review — Sections E and F, and Final Capstone Performance Task
These are open-ended, integrated production tasks. Evaluate the feature article, general-audience adaptation, presentation, question-and-answer performance, and reflection against the assessment focus listed under the Final Capstone Performance Task above.
Looking Ahead
いまできること — What you can do now
You can plan, research, draft, compare sources within, adapt, revise, present, and defend a substantial piece of Japanese writing from proposal to publication. You can conduct a professional interview using appropriate keigo, report findings honestly across sources that disagree, and reflect in Japanese on your own language use. This completes Volume IV: Professional, Academic, and Cultural Communication, and brings your control of Japanese to a functional C1 level across listening, speaking, reading, and writing.
