Master Class: Research-Style Academic Japanese (N1)

In professional and academic Japanese (論文・学会発表), the language shifts from communicative fluency to objective precision. Academic Japanese requires specific grammatical structures, high-register vocabulary, and hedging techniques to present arguments logically and persuasively.論文学会発表

This guide focuses on the critical transformations needed to elevate your Japanese to a peer-reviewed, research-grade level.

1. The Core Philosophy: Objectivity & Hedging

In academic writing, you must avoid subjective assertions (e.g., ～と思う) and overly dramatic N1 grammar (e.g., ～極まりない). Instead, use hedging expressions to show intellectual humility and objective stance.思極

2. Elite Academic Grammar Patterns

Pattern 1: 〜を踏まえ（て） (Based on / Taking into account)

• Connection: [Noun] + を踏まえ踏
• Usage: Used to establish the foundation of your hypothesis or methodology.

Kanji Focus: 踏 (To step on / Base upon)

• Stroke Count: 15 strokes.
• Radical: 足 (foot) on the left, indicating physical grounding; 沓 (sole/shoe) on the right. In academic Japanese, it metaphorically means "standing firmly on previous research."足沓

**Example:**
先行研究の知見を踏まえ、本稿では新たな分析モデルを提示する。
Senkō kenkyū no chiken o fumae, honkō de wa aratana bunseki moderu o teiji suru.
"Taking into account the findings of prior research, this paper presents a new analytical model."

Pattern 2: 〜を余儀なくされる (To be forced to...)

• Connection: [Noun] + を余儀なくされる / [Verb-nai form (drop ない)] + ざるを得ない余儀得
• Usage: Essential for the "Limitations" (限界) section of a paper. It explains factors beyond the researcher's control without sounding whiny.限界

**Example:**
サンプル数の制限により、分析手法の変更を余儀なくされた。
Sanpuru-sū no seigen ni yori, bunseki shuhō no henkō o yoginaku sareta.
"Due to limitations in sample size, a change in the analytical methodology was rendered unavoidable."

3. The "Academic Makeover" (Before & After)

Observe how a standard high-level sentence is transformed into publication-ready academic prose.

• Before (Conversational/General N1):

  このデータを見ると、若者のスマホ依存がどんどん進んでいることがよく分かります。
  (Looking at this data, we can clearly see that young people's smartphone addiction is progressing rapidly.)見若者依存進

  見若者依存進

• After (Academic/Research Style):

  本データは、若年層におけるスマートフォンへの依存傾向が深刻化している実態を裏付けている。
  (These data corroborate the reality of the intensifying trend of smartphone dependency among the youth demographic.)本若年層依存

  本若年層依存

Key Upgrades:

1. 若者 (Youth) $\rightarrow$ 若年層 (Youth demographic - precise sociological term).若者年層
2. どんどん進んでいる $\rightarrow$ 深刻化している (Intensifying/becoming acute).進深刻化
3. よく分かります $\rightarrow$ 実態を裏付けている (Corroborates the reality - objective verification).分実態裏付

4. Quick Practice

Transform the following sentence into Academic Japanese using 〜を示唆している (suggests) and 〜に起因する (stems from).示唆起因

• Exercise: "The experiment succeeded because we changed the temperature."
• Model Answer:
  実験の成功は、温度設定の変更に起因するものと考えられ、本手法の有効性を示唆している。実験成功温度
