5.3 Targets, Viewpoints & Evaluation Criteria (〜に対して, 〜にとって, 〜に関して, 〜に基づいて)

5.3 Targets, Viewpoints & Evaluation Criteria (対象・視点・基準・根拠)

At the elementary level, Japanese learners rely heavily on single-character case particles—such as に (ni), で (de), and と (to)—to mark targets, locations, and partners. However, single particles are inherently polysemous and broad. As you advance into intermediate Japanese (JLPT N3), the language demands far greater precision in delineating:

• Who or what is the direct target of an attitude or contrastive comparison?
• From whose specific psychological viewpoint is a subjective value judgment being made?
• What is the overarching conceptual topic under academic or business investigation?
• What factual data, legal principle, or empirical evidence serves as the foundational basis for an action?

To satisfy these communicative demands, intermediate Japanese employs Compound Postpositions (複合格助詞, fukugō kakujoshi / 連語). In this section, we analyze the four most heavily tested compound markers on the JLPT N3:

1. Directed Action, Ratio & Contrast: 〜に対して / 〜に対する (ni taishite / ni taisuru)
2. Subjective Evaluation & Standpoint: 〜にとって / 〜にとっての (ni totte / ni totte no)
3. Thematic Scope & Broad Topic: 〜に関して / 〜に関する (ni kanshite / ni kansuru)
4. Empirical Grounding & Factual Basis: 〜に基づいて / 〜に基づく (ni motozuite / ni motozuku)

1. Directed Target, Ratio & Contrast: 〜に対して / 〜に対する

Syntactic Forms

• Adverbial Clause Linker: Noun + に対して (modifies following verbs/clauses)
• Noun Modifier: Noun + に対する + Noun (modifies following noun phrase)
• Contrastive Linker: Verb/Adj Plain + のに対して (contrasts two contrasting clauses)

┌────────────────────────────────────────────────────────────────────────┐
│                     THE 3 FUNCTIONS OF 〜に対して                      │
├──────────────────┬─────────────────────────────────────────────────────┤
│ 1. Direct Target │ Interpersonal attitude, behavior, or emotion toward │
│ 2. Proportional  │ Ratio or rate: "per / for every X, there is Y"      │
│ 3. Contrast      │ Comparison: "while Subject A is X, Subject B is Y"  │
└──────────────────┴─────────────────────────────────────────────────────┘

Function 1: Target of Action, Attitude or Feeling (対象・態度)

• Nuance: Indicates the person, group, or entity toward whom a specific behavior, speech act, psychological attitude, or policy is directed ("toward / against / in regard to").
• Example: 目上の人に対しては、常に礼儀正しい言葉遣いを心がけるべきだ。<br>Meue no hito ni taishite wa, tsune ni reigi tadashii kotobazukai o kokorogakeru beki da.<br>(Toward one's superiors, one should always make an effort to use polite language.)
• Example: お客様からの厳しいクレームに対して、誠心誠意対応した。<br>Okyaku-sama kara no kibishii kurēmu ni taishite, seishin seii taiō shita.<br>(We responded with utmost sincerity to the demanding customer complaint.)
• Noun Modifying Example (〜に対する): 政府の新しい増税政策に対する国民の批判が高まっている。<br>Seifu no atarashii zōzei seisaku ni taisuru kokumin no hihan ga takamatte iru.<br>(Public criticism toward the government's new tax-hike policy is intensifying.)

Function 2: Ratio & Proportion (割合・対比比率)

• Nuance: States a quantitative proportion or mathematical comparison ("for every... / per...").
• Example: このインターナショナルスクールでは、生徒5人に対して1人の専任ネイティブ教師が配置されている。<br>Kono intānashonaru sukūru de wa, seito gonin ni taishite hitori no sennin neitibu kyōshi ga haichi sarete iru.<br>(In this international school, one dedicated native teacher is assigned for every five students.)

Function 3: Direct Contrast between Two Subjects (対比「〜のに対して」)

• Nuance: Compares two distinct subjects or conditions that stand in sharp, polar opposition ("in contrast to / whereas / while").
• Example: 兄は活発でアウトドアが好きなのに対して、弟は物静かで読書を好む。<br>Ani wa kappatsu de autodoa ga suki na no ni taishite, otōto wa monogizuka de dokusho o konomu.<br>(Whereas the older brother is active and loves the outdoors, the younger brother is quiet and prefers reading.)

2. Subjective Viewpoint & Evaluation: 〜にとって / 〜にとっての

Core Meaning & Nuance

〜にとって (ni totte) translates as "for / to (someone)" or "from the perspective of (someone)". It establishes the subjective frame of reference or standpoint from which an evaluation, judgment, or emotional assessment is made.

Strict Predicate Constraints (The Gold Standard Rule)

Unlike generic relational markers, 〜にとって strictly demands that the concluding predicate express a subjective value judgment, personal evaluation, degree of importance, or psychological status.

┌────────────────────────────────────────────────────────────────────────┐
│                     MANDATORY PREDICATES WITH 〜にとって               │
├────────────────────────────────────────────────────────────────────────┤
│ • Importance & Value   : 大切だ, 重要だ, 必要不可欠だ, 貴重だ, 宝物だ    │
│ • Difficulty & Hardship: 難しい, 困難だ, 大変だ, 負担だ, 不可能だ       │
│ • Subjective Evaluation: 意味がある, 誇りだ, 有利だ, 不利だ, 迷惑だ     │
└────────────────────────────────────────────────────────────────────────┘

Forbidden Predicates with 〜にとって

You cannot use 〜にとって with pure physical actions, factual historical events, or objective statements that lack an evaluative stance:

• ❌ 私にとって、毎朝新聞を読んだ。 → Ungrammatical! (Reading a newspaper is a pure action, not a value judgment)
• ⭕️ 私にとって、毎朝新聞を読むことは大切な習慣だ。 → Correct! (Evaluated as "an important habit")
• ❌ 彼にとって、手紙を書いた。 → Ungrammatical! (Use 彼に対して or 彼に)
• ⭕️ 彼にとって、家族と過ごす時間が何よりも重要だ。 → Correct! (Evaluated as "most important")

Syntactic Connection Rules

• Adverbial Linker: Noun (Person / Organization / Entity) + にとって
• Noun Modifier: Noun + にとっての + Noun

Exemplary Sentences

• 現代のビジネスパーソンにとって、語学力とITリテラシーは必須のスキルである。<br>Gendai no bijinesu pāson ni totte, gogakuryoku to aitī riterashī wa hissu no sukiru de aru.<br>(For modern business professionals, language skills and IT literacy are essential capabilities.)

3. Thematic Scope & Inquiry: 〜に関して / 〜に関する

Core Meaning & Nuance

〜に関して (ni kanshite) translates as "regarding...", "concerning...", "with respect to...", or "on the topic of...". It designates the overarching theme, domain, or subject matter being examined, discussed, investigated, or explained.

Comparison with Elementary 〜について (ni tsuite)

While 〜について is the standard colloquial phrase for "about X", 〜に関して is its formal, academic, and journalistic equivalent. Moreover, 〜に関して possesses a broader semantic scope: it encompasses not just the narrow entity itself, but all associated peripheral issues, background circumstances, and systemic context.

┌────────────────────────────────────────────────────────────────────────┐
│                 〜について  VS.  〜に関して SPECTRUM                   │
├────────────────────────────────────┬───────────────────────────────────┤
│ 〜について (*ni tsuite*)           │ 〜に関して (*ni kanshite*)        │
├────────────────────────────────────┼───────────────────────────────────┤
│ • Narrow, direct focal topic       │ • Broad, overarching systemic area│
│ • Casual to polite spoken register │ • Formal, written, journalistic   │
│ • Direct inquiry: "About this box" │ • Broad inquiry: "Regarding trade"│
└────────────────────────────────────┴───────────────────────────────────┘

Syntactic Connection Rules

• Adverbial Linker: Noun + に関して / Noun + に関しては
• Noun Modifier: Noun + に関する + Noun

Typical Following Predicates

〜に関して typically governs verbs of cognition, research, communication, and inquiry:

• 調べる (investigate), 調査する (survey), 議論する (debate), 発表する (announce), 説明する (explain), 質問する (inquire), 研究する (research).

Exemplary Sentences

• 新しい都市開発計画に関して、来週住民説明会が開かれる予定です。<br>Atarashii toshi kaihatsu keikaku ni kanshite, raishū jūmin setsumeikai ga hirakareru yotei desu.<br>(Regarding the new urban development plan, a briefing for residents is scheduled to be held next week.)

4. Empirical Grounding & Factual Basis: 〜に基づいて / 〜に基づく

Core Meaning & Nuance

〜に基づいて (ni motozuite) translates as "based upon...", "grounded in...", or "in accordance with (evidence/principles)...". It signifies that a subsequent action, policy, judgment, architectural design, or creative work takes a specific set of empirical data, legal frameworks, survey findings, historical facts, or foundational theories as its fundamental bedrock.

Syntactic Connection Rules

• Adverbial Linker: Noun + に基づいて / Noun + に基づき (formal literary form)
• Noun Modifier: Noun + に基づく + Noun / Noun + に基づいた + Noun

High-Frequency Nouns Preceding 〜に基づいて

This pattern binds almost exclusively with nouns representing objective benchmarks, standards, or foundational source materials:

│               HIGH-YIELD ANCHOR NOUNS FOR 〜に基づいて                 │
├──────────────────┬─────────────────────────────────────────────────────┤
│ Data & Evidence  │ 調査結果 (survey results), データ (data), 実験結果  │
│ Legal & Rules    │ 法律 (laws), 規約 (regulations), 基本方針 (policy)  │
│ Truth & Reality  │ 事実 (facts), 実際の経験 (actual experience)        │
│ Theory & Concept │ 独自の理論 (original theory), 科学的根拠 (evidence) │
└──────────────────┴─────────────────────────────────────────────────────┘

Exemplary Sentences

• 市民1,000人を対象に行ったアンケート調査の結果に基づいて、次年度の予算配分を決定した。<br>Shimin sennin o taishō ni okonatta ankēto chōsa no kekka ni motozuite, jinedo no yosan haibun o kettei shita.<br>(Based upon the results of a questionnaire survey conducted on 1,000 citizens, we determined the next fiscal year's budget allocation.)

Contrast: 〜に基づいて vs. 〜に応じて

• 〜に基づいて (ni motozuite): Takes a fixed, static baseline/data point as the foundation ("based on the law / survey").
• 〜に応じて (ni ōjite): Adjusts dynamically in response or proportion to a changing variable ("according to budget / age / weather"). Example: 予算に応じてプランを選ぶ (choose a plan according to the budget).

6. Strategic Exam Protocol for Sentence Composition (文の組み立て ★)

In Grammar Problem 2 (Sentence Composition ★), compound postpositions are prime testing candidates because their noun-modifying forms (に対する, にとっての, に関する, に基づく) dictate rigid word order:
