Japanese Court Judgments: 原告, 被告, 主文, 理由

Core examples: 原告, 被告, 主文, 理由, 事実, 請求, 証拠, 判決, 控訴, 認定.

The outcome is not hidden in the longest paragraph

A Japanese court judgment may contain long passages of facts, claims, evidence, and legal reasoning. A learner starts at the beginning and gets lost. But judgments have structure. The most important result often appears in a compact section:

主文

Then the judgment explains:

理由

The reader must know which section states the legal outcome and which section explains the path.

The key principle is:

Read the judgment structure before reading the prose.

This article is language-literacy guidance, not legal advice.

Parties: 原告 and 被告

原告

means plaintiff.

被告

means defendant.

In civil cases, 原告 brings the claim, and 被告 responds. In criminal contexts, terms differ, and 被告人 is used for the accused/defendant in criminal proceedings.

代理人 representative/attorney

Learner action: identify parties before reading claims.

主文: the holding/result

主文

is the operative part/main text of a judgment. It states what the court orders or decides.

It may say things like:

原告の請求を棄却する。 The plaintiff’s claim is dismissed.

被告は原告に対し、金〇〇円を支払え。 The defendant shall pay the plaintiff X yen.

訴訟費用は原告の負担とする。 Litigation costs shall be borne by the plaintiff.

Learner action: read 主文 first. It tells you the result.

理由: reasoning

理由

means reasons. In a judgment, this section explains the facts, issues, evidence, legal standards, and reasoning supporting the 主文.

It may include:

• claims of parties,
• facts found,
• evidence evaluation,
• legal issue,
• application of law,
• conclusion.

The reasoning may be much longer than the result.

事実 and 認定

事実

means facts.

認定

means finding/recognition by the court.

Example:

裁判所は、次の事実を認定した。 The court found the following facts.

A fact alleged by a party is not the same as a fact found by the court. This distinction is crucial.

Learner action: distinguish 주장/claim-like statements from 認定 facts.

請求

請求

means claim/request/demand in legal context.

Examples:

損害賠償請求 claim for damages

原告の請求 plaintiff’s claim

請求を棄却する dismiss the claim

請求 does not simply mean “request” in ordinary politeness. In judgments, it is a legal demand.

証拠

証拠

means evidence.

Related:

証人 witness

書証 documentary evidence

証言 testimony

立証 proof/establishing by evidence

Judgments may state whether evidence supports or does not support a claim.

判決 and 控訴

判決

means judgment.

控訴

means appeal to a higher court, usually from district court to high court depending on system.

Related:

上告 final appeal to the Supreme Court in certain contexts

確定 become final/conclusive

A news article may report a judgment but also note whether a party plans to appeal.

News reports about judgments

News articles often compress judgment language:

東京地裁は、原告の請求を棄却した。 Tokyo District Court dismissed the plaintiff’s claim.

被告に賠償を命じた。 ordered the defendant to pay damages.

判決を不服として控訴する方針。 plans to appeal, dissatisfied with the judgment.

Learner action: news may summarize the outcome but omit reasoning details.

原告

Plaintiff.

Learner action: party bringing claim.

被告

Defendant.

Learner action: party responding to claim.

主文

Operative holding/result.

Learner action: read first.

理由

Reasons/reasoning.

Learner action: explains path to result.

事実

Facts.

Learner action: distinguish alleged facts from found facts.

請求

Legal claim/demand.

Learner action: not just polite request.

証拠

Evidence.

Learner action: basis for factual findings.

判決

Judgment.

Learner action: court decision.

控訴

Appeal.

Learner action: case may not be final.

認定

Court finding.

Learner action: fact/status recognized by court.

Judgment-reading scaffold

For a Japanese court judgment or summary:

1. Identify court and date.
2. List parties: 原告, 被告.
3. Read 主文 first.
4. Identify claim: what did the plaintiff request?
5. Outline facts alleged by parties.
6. Find facts the court 認定した.
7. Identify legal issue.
8. Read 理由 for reasoning.
9. Check result: granted, dismissed, partially granted?
10. Check appeal status: 控訴, 上告, 確定.

Judgment structure table

Court judgments are structured documents. Read by section.

If you start with the longest paragraph, you may miss the result. Start with 主文.

Alleged fact versus found fact

Legal Japanese distinguishes:

原告は〜と主張した。 The plaintiff alleged/argued that...

裁判所は〜と認定した。 The court found that...

These are not the same. A claim is not a court finding. This distinction is central to judgment reading.

News-summary caution

News reports may say:

東京地裁は請求を棄却した。 被告に賠償を命じた。 控訴する方針。

News summaries compress the judgment and may omit legal reasoning, procedural posture, or whether the judgment is final. For serious reading, distinguish the news account from the judgment text.

A strong tool for this article would turn a judgment into a case brief.

Suggested functions:

1. Section detector: 主文, 理由, 事実, 判断.
2. Party map: 原告, 被告, 代理人.
3. Claim extractor: 請求.
4. Evidence and finding labels: 証拠, 認定.
5. Outcome summary.
6. Appeal-status flag.
7. Plain-language case brief.
8. Legal-advice caution label.

Final rule

A court judgment is not ordinary prose. It is structured authority.

Read 主文 for the result, 理由 for the reasoning, 原告 and 被告 for parties, 請求 for legal demand, 証拠 for proof, and 認定 for court-found facts.

In legal Japanese, structure tells you where the law speaks.

Revision quality-control checklist

This remediated batch was checked against the 201–220 outline goals and strengthened in six ways:

1. Added cross-CJK transfer safeguards for names, company names, counters, cognates, Mandarin/Korean transfer, and global loanword strategy.
2. Expanded practical parsing tables for high-stakes documents: employment contracts, corporate records, annual reports, patents, medical forms, medicine labels, public-health notices, and judgments.
3. Sharpened recognition-versus-action guidance so readers know when a term is merely informative and when it affects legal, medical, financial, or procedural action.
4. Added stronger safety framing for legal, medical, pharmaceutical, financial, and public-health articles.
5. Added more explicit “do not overtrust character recognition” warnings across the CJK-focused pieces.
6. Preserved the original article structure while improving the batch’s usefulness as durable reference material.

The result remains a publication draft rather than a citation-heavy academic or professional-advice document. For legal, medical, tax, finance, cybersecurity, and public-safety contexts, these articles should be positioned as language-literacy resources, not substitutes for qualified professional guidance.

These drafts are written as publication-ready educational articles rather than academic papers. Useful technical/reference anchors for future source-linking include:

• Japanese, Chinese, and Korean name-handling conventions, including furigana, pinyin, Hangul transcription, Hanja, romanization, and public-figure editorial practices.
• Japanese corporate-document conventions for legal forms, registration, articles of incorporation, representative directors, shareholder meetings, and corporate governance language.
• Japanese financial-reporting and investor-relations documents for 売上高, 営業利益, 通期, 見通し, 配当, and セグメント.
• Japanese technical and policy sources for AI, patents, pharmaceutical labels, medical intake forms, public-health notices, and hospital-stage language.
• Japanese legal-literacy resources for employment contracts, court judgments, party labels, claims, evidence, holdings, and appeal terminology.
• Cross-CJK linguistic references on kanji/hanzi/hanja, Sino-Xenic vocabulary, kanbun, Chinese classics, cognates, false friends, and cross-language transfer.
