8.2 Text Grammar: Logical Connectives & Discourse Markers (接続詞・指示語)

In the JLPT N3 examination, Problem 3 (問題3: 文章の文法 — Text Grammar) represents the bridge between sentence-level grammatical knowledge and extended reading comprehension. Rather than evaluating isolated sentences, Problem 3 presents an authentic, cohesive reading passage of roughly 400 to 500 Japanese characters (usually an explanatory essay, personal column, or opinion article) with 5 embedded blanks (Questions 19 through 23).

To master Problem 3, you cannot rely on local sentence translation alone. You must analyze the discourse logic (文章の論理構造), the cohesive signaling provided by logical connectives (接続詞, setsuzokushi), and the anaphoric references established by contextual demonstratives (指示語, shijigo).

1. Comprehensive Taxonomy of Logical Connectives

Connectives are the road signs of Japanese prose. They signal to the reader whether the upcoming sentence will provide an example, introduce a contradiction, explain an underlying cause, or synthesize a final conclusion.

Family 1: Adversative & Contrast (逆接・対比)

Adversative connectives indicate a sharp reversal of expectation or a structural juxtaposition between two entities:

1. しかし (shikashi) — Universal Adversative:

   • The standard, formal written connective meaning "However / But". It introduces a statement that contradicts the natural expectation formed by the preceding sentence.
   • Example: 多くの人は彼の計画に反対した。しかし、彼は信念を曲げなかった。(Many opposed his plan. However, he did not compromise his conviction.)

2. ところが (tokoroga) — Defied Expectation / Unexpected Twist:

   • Carries a strong sense of surprise, unexpected reality, or unintended result. Clause B is always an objective factual development that was beyond the speaker's control.
   • Exam Rule: Clause B with ところが cannot express the speaker's personal intention, command, or request (*ところが、頑張ろう is invalid).
   • Example: 昨夜は快晴だった。ところが、朝起きると一面の大雪になっていた。(Last night was clear. To my surprise, when I woke up, the ground was covered in heavy snow.)

3. それに対して (sore ni taishite) — Explicit Dual-Entity Contrast:

   • Contrasts two distinct groups, individuals, or phenomena ("In contrast to that... / On the other hand...").
   • Example: 兄は非常に社交的な性格だ。それに対して、弟は物静かで読書を好む。(The elder brother is very outgoing. In contrast, the younger brother is quiet and prefers reading.)

4. 一方で (ippō de) — Parallel Duality:

   • Introduces a parallel, often contrasting perspective on the same topic ("On the one hand..., yet on the other hand...").
   • Example: 都市部は利便性が高い。一方で、生活費や家賃の高さが課題である。(Urban areas offer great convenience. On the other hand, high living costs and rent remain challenges.)

Family 2: Cause, Reason & Result (因果関係・理由・結果)

The JLPT frequently tests the distinction between Forward Causal connectives (Cause → Result) and Backward Causal connectives (Conclusion → Reason).

┌─────────────────────────────────────────────────────────────────────────────────┐
│                     FORWARD vs. BACKWARD CAUSAL CONNECTIVES                     │
├─────────────────────────────────────────────────────────────────────────────────┤
│  FORWARD CAUSAL: [ Premise / Cause ]  ──►  したがって / そのため  ──► [ Result ] │
│  "It rained heavily. Therefore, the outdoor tournament was cancelled."          │
│                                                                                 │
│  BACKWARD CAUSAL: [ Conclusion / Fact ] ──► なぜなら / というのは ──► [ Reason ]│
│  "The tournament was cancelled. The reason is that it rained heavily."          │
└─────────────────────────────────────────────────────────────────────────────────┘

1. したがって (shitagatte) — Formal Logical Consequence:

   • High-register, rational conclusion ("Therefore / Consequently / In accordance with these facts"). Standard in academic and expository essays.
   • Example: 円安が急速に進行している。したがって、輸入品の価格高騰は避けられない。(The yen is depreciating rapidly. Therefore, price increases on imported goods are unavoidable.)

2. そのため (sono tame) — Objective Cause and Effect:

   • Neutral, objective cause-effect link ("Because of that / For that reason").
   • Example: 沿線で信号機の故障が発生した。そのため、全線で運転を見合わせている。(A signal failure occurred along the line. For that reason, operations are suspended on all lines.)

3. そこで (sokode) — Deliberate Action in Response to Situation:

   • Connects a given background situation to a deliberate decision, action, or measure taken by an agent to resolve it ("Under these circumstances / Accordingly, we decided to...").
   • Example: 新商品の売れ行きが伸び悩んでいた。そこで、若者向けの広報戦略を見直すことにした。(Sales of the new product were sluggish. Thereupon, we decided to overhaul our PR strategy targeting youth.)

4. なぜなら（ば） (nazenara [ba]) — Introducing the Core Cause:

   • Introduces the causal explanation for a previously stated claim. It must correlate with a sentence-ending causal marker such as 〜からだ (because...) or 〜ためである.
   • Example: 現代人は十分な睡眠をとるべきだ。なぜなら、睡眠不足は免疫力を著しく低下させるからだ。(Modern people should get adequate sleep. The reason is that sleep deprivation significantly reduces immunity.)

5. というのは (to iu no wa) — Explanatory Background Elaboration:

   • Softer explanatory connective ("This is because... / To explain why..."), often providing contextual backstory.

Family 3: Addition & Supplementation (添加・補足)

1. また (mata) — Neutral Addition:
   • Equivalent to "Also / In addition". Links two independent facts of equal weight.
2. さらに (sarani) — Progressive Escalation:
   • Denotes a step upward in degree, quantity, or importance ("Furthermore / Moreover / What is more").
   • Example: このアプリは操作が簡単だ。さらに、多言語に対応している点も優れている。(This app is easy to operate. Furthermore, its multilingual support is also outstanding.)
3. そのうえ (sono ue) — Cumulative Stacking:
   • Reinforces the preceding sentiment in the same valence (stacking positive on positive, or negative on negative: "On top of that / To make matters worse").
   • Example: 昨日は大雨で靴が濡れた。そのうえ、電車が遅延して遅刻してしまった。(Yesterday shoes got soaked in heavy rain. On top of that, the train was delayed and I ended up late.)
4. なお (nao) — Supplementary Appendix:
   • Adds a supplementary condition, exception, or administrative note at the end of an announcement ("Please note that / Incidentally").

---

Family 4: Rephrasing, Summary & Conclusion (換言・要約・結論)

1. つまり (tsumari) — Rephrasing & Conceptual Synthesis:
   • Translates as "In other words / That is to say / In short". Used by authors to condense complex prior arguments into a single punchy thesis statement.
   • Example: 彼は時間も守らず、約束も果たさない。つまり、社会人としての責任感に欠けているのだ。(He doesn't keep time and doesn't fulfill promises. In other words, he lacks professional responsibility.)
2. すなわち (sunawachi) — Formal Equivalence / Definition:
   • High-register definition marker equating Term A with Concept B ("Namely / Specifically / Viz.").
3. 要するに (yōsuru ni) — Distilling the Core Essence:
   • Strips away extraneous details to deliver the bottom line ("In short / To put it simply").

2. Demonstratives in Discourse Context (指示語の文脈指示)

In JLPT N3 reading texts, demonstrative pronouns (コ・ソ・ア・ド系列) do not merely point to physical objects in physical space (現場指示); they perform textual anaphora (文脈指示), referring to abstract concepts, antecedent phrases, or upcoming statements.

┌─────────────────────────────────────────────────────────────────────────────────┐

│ Series       │ Contextual Function           │ Typical Usage in Problem 3       │
├──────────────┼───────────────────────────────┼──────────────────────────────────┤

│  こう)       │                               │ about to analyze deeply.         │
├──────────────┼───────────────────────────────┼──────────────────────────────────┤
│ ソ系列       │ Objective Anaphoric Reference │ Standard reference to a noun,    │
│ (それ, その, │ (Neutral Retrieval)           │ phrase, or entire clause         │
│  そうした)   │                               │ mentioned in preceding sentence. │
├──────────────┼───────────────────────────────┼──────────────────────────────────┤
│ ア系列       │ Distal Shared Knowledge       │ Evokes a concept assumed to be   │
│ (あれ, あの, │ (Mutual Cognitive Domain)     │ mutually known to both author    │
│  ああした)   │                               │ and reader from common culture.  │
└──────────────┴───────────────────────────────┴──────────────────────────────────┘

Critical Difference: この vs. その in Expository Texts

• その (sono): Refers objectively to an antecedent entity mentioned in the preceding text without emotional attachment. In over 80% of Problem 3 anaphoric items, その is the standard objective referent.
• この (kono): Used when the author treats the antecedent as an active, central object of immediate examination ("this problem before us"), or when referring to the entire overarching theme of the essay.
• そうした / このような (sōshita / kono yō na): Used to encapsulate a category of phenomena described across several preceding sentences ("Such phenomena / situations of this kind").

3. Step-by-Step Problem 3 Passage Solving Strategy

When tackling a Problem 3 text grammar passage on the exam, execute this 4-step workflow:

┌─────────────────────────────────────────────────────────────────────────────────┐
│                     PROBLEM 3 TEXT DECODING WORKFLOW                            │
├─────────────────────────────────────────────────────────────────────────────────┤
│ 1. Scan Paragraph Openings: Read the first 1-2 sentences of the entire passage   │
│    to establish the overarching topic and author's tone.                        │
│                                                                                 │
│ 2. Map Sentence Polarity: Before each connective blank, assign a (+) or (-)     │
│    logical vector to Sentence A (before blank) and Sentence B (after blank).    │
│    - (+) to (-) or (-) to (+) → Adversative (しかし, ところが)                   │
│    - (+) to (+) or (-) to (-) → Additive/Causal (さらに, したがって)             │
│                                                                                 │
│ 3. Check Causal Directionality: If the relationship is causal, check whether    │
│    Sentence B is the *result* (したがって) or the *reason* (なぜなら + からだ).   │
│                                                                                 │
│ 4. Track Demonstrative Antecedents: For demonstrative blanks, draw a physical    │
│    line back to the specific noun or predicate clause being referenced.         │
└─────────────────────────────────────────────────────────────────────────────────┘

By mastering connective classifications and demonstrative reference mechanics, you will transform Problem 3 from an unpredictable guessing game into a systematic, high-scoring section.
