Elite Japanese Study Guide: Master N1 Synonyms (Nuance & Precision)

At the JLPT N1 level, vocabulary acquisition shifts from learning meanings to mastering nuances. To pass the exam and speak like a native professional, you must understand the subtle boundaries between words that bilingual dictionaries translate identically.

This guide dissects three high-frequency N1 synonym pairs.

Pair 1: "Still / As Always"

依然として (いぜんとして) vs. 相変わらず (あいかわらず)

Both adverbs describe a state that remains unchanged. However, their tone, objectivity, and context differ drastically.

[State remains unchanged] ───► Objective/Formal/Often Negative ───► 依然として
                         └───► Subjective/Conversational ────────► 相変わらず

1. 依然として (Izen to shite)

• Nuance: Highly formal, objective, and analytical. It is heavily used in news broadcasts and business reports. It strongly implies a stagnant, often undesirable situation that should have changed but didn't.
• Example:
  • 犯人の行方は依然として分かっていない。犯人行方依然
  • Hannin no yukue wa izen to shite wakatte inai.
  • The suspect’s whereabouts remain unknown. (Objective, serious report).
  犯人行方依然

2. 相変わらず (Aikawarazu)

• Nuance: Casual to semi-formal, subjective, and personal. It can express admiration, relief, or mild exasperation.
• Example:
  • 彼は相変わらず遅刻ばかりしている。彼相変遅刻
  • Kare wa aikawarazu chikoku bakari shite iru.
  • He is still doing nothing but arriving late, as usual. (Personal observation/exasperation).
  彼相変遅刻

Pair 2: "To Overcome / Resolve"

克服 (こくふく) vs. 打開 (だかい)

Both verbs mean to get through a difficult situation, but they target different types of obstacles.

1. 克服する (Kokufuku suru)

• Nuance: To conquer an internal or physical weakness, such as an illness, fear, handicap, or bad habit. It requires personal effort and willpower over time.
• Collocations: 病気 (illness), 弱点 (weakness), 高所恐怖症 (fear of heights).病気弱点高所
• Example:
  • 猛特訓の末、ついに苦手を克服した。猛特訓末苦手
  • Mōtokkun no sue, tsuini nigate wo kokufuku shita.
  • After intense training, I finally overcame my weakness.
  猛特訓末苦手

2. 打開する (Dakai suru)

• Nuance: To break a deadlock or resolve an external, stagnant situation. It literally means to "strike open" a path when progress has completely stalled.
• Collocations: 膠着状態 (deadlock), 難局 (difficult situation), 資金難 (financial distress).膠着状態難局
• Example:
  • 膠着した交渉を打開するため、新たな提案を行った。膠着交渉打開
  • Kōchaku shita kōshō wo dakai suru tame, aratana teian wo okonatta.
  • We made a new proposal to break the deadlock in the stalled negotiations.

Both nouns indicate the starting point or "trigger" for a change, but they belong to different registers.

• Example (Kikkake):

  • アニメをきっかけに、日本語の勉強を始めた。日本語勉強始
  • Anime wo kikkake ni, nihongo no benkyō wo hajimeta.
  • I started studying Japanese because of anime. (Casual, personal trigger).
