～にしろ～にせよ／～にしろ～にしろ – Either way… (two cases)

1. Basic structure

Pattern: ～うが～うが (connects two possibilities/opposites: "whether A or B.../regardless of A or B..."). Essentially a repeated volitional/conjectural form + が.

Note: Volitional V意向形 = 五段: 書く→書こう, 行く→行こう; 一段: 食べる→食べよう, 見る→見よう.

2. Core meaning & detailed analysis

• Main meaning: Present two possibilities/contrasts and assert that the result/stance is unchanged. "Whether A or B, (it) ...", "Regardless of A or B, ...".
• Pragmatic value: Emphasizes determination, disregard for conditions, or the consistency of a rule/judgment. Strong tone, more formal than ordinary conversational patterns.
• Information structure: Clause Aうが Bうが (concessive–enumerative clause) + main clause (conclusion/stance: 関係ない・問わない・変わらない・続ける・行う…).
• Constraints: The two sides A and B should be the same part-of-speech category and be paired/contrasting (高い↔低い, 晴れ↔雨, 行く↔やめる).

3. Illustrative examples

• 好きだろうが 嫌いだろうが、与えられた仕事はやり切るべきだ。

  Whether you pass or fail, taking on the challenge is worthwhile.
• 誰であろうが 何であろうが、不正は許されない。
  Whoever it is or whatever it is, misconduct will not be tolerated.

4. Usage & nuance

• Position: The chunk AうがBうが appears at the beginning or in the middle of the sentence, followed by the concluding clause (typically expressing a firm/unaffected stance).
• Typical collocations following the pattern: 関係ない・問題ない・問わない・構わない・同じだ・変わらない・やり抜く・続ける・実施する など.
• Formality: であろうが (formal/written) > だろうが (colloquial). With Aい use かろうが (literary form).
• Nuance: Strong, emphasizing resolve/rules. Often used in announcements, speeches, policy documents, or statements expressing a stance.
• Parallel form: Ensure parallel part-of-speech and logic: if A is an N, B is also an N; if A is V意向, B is also V意向.

5. Comparison, distinctions, and similar patterns

• ～うが～まいが: "Whether to do or not do (the same verb)". Different from ～うが～うが (lists two possibilities/opposites that can be two different words). Example: 行こうが行くまいが vs 晴れだろうが雨だろうが.
• ～にしろ～にしろ / ～であれ～であれ: Similar meaning "whether A or B". であれ is formal; にしろ is more neutral, more conversational. ～うが～うが has a stiffer tone, leaning toward written/emphatic use.
• ～ても～ても: Emphasizes "no matter how many times/to what extent" rather than listing two opposing sides. Example: 何度やってもできない.
• ～うと～うと: A variant using と instead of が, with nearly the same nuance: 雨が降ろうと風が吹こうと＝降ろうが吹こうが.
• ～だろうが／であろうが vs ～ろうが: With Aい use かろうが; with N/Na use だろうが/であろうが; do not use "静かろうが".

6. Extended notes

• Rhythm: The repeating pattern "A…が B…が" creates a rhetorical cadence, fitting for speeches, headlines, slogans.
• Implicit negation: Often implies "not influenced by condition A/B". Therefore, the following clause rarely expresses something easily swayed.
• Combining with interrogatives: It can extend to "誰であろうが・いつであろうが・どこであろうが…", and can also be paired in parallel: "誰であろうが 何であろうが…".
• Style: For a lighter/conversational feel, consider 〜にしろ〜にしろ or 〜でも〜でも.
• Irregular i-adjective note: いい → よい → よかろうが. Example: よかろうが 悪かろうが.

7. Variants & fixed expressions

• Form variants: ～うと～うと / ～であろうと～であろうと (formal) / ～だろうが～だろうが (colloquial with N/Na).
• Common fixed pairs:
  • 晴れだろうが 雨だろうが
  • 暑かろうが 寒かろうが
  • 多かろうが 少なかろうが
  • 好きだろうが 嫌いだろうが
  • 子どもであろうが 大人であろうが
  • 平日であろうが 休日であろうが

8. Common mistakes & JLPT traps

• Wrong morphology: Using the plain form instead of volitional/conjectural. Wrong: 高いが 安いが. Correct: 高かろうが 安かろうが.
• Mixing parts of speech: A is V意向, B is N + だろう (not parallel), making the sentence awkward. Keep the same category or a clear contrasting pair.
• Confusion with ～うが～まいが: JLPT often sets traps with the pair "行こうが 行くまいが" (one verb, two possibilities) vs "晴れだろうが 雨だろうが" (two contrasting nouns). Distinguish the functions clearly.
• いい → よかろう: Test-takers often write "いいかろうが" (wrong). Correct: よかろうが.
• Overly strong tone: In casual conversation it can sound stiff. In tests, choose a pattern appropriate to the context: であれ/にしろ may be more natural.
• Missing concluding clause: The pattern usually requires a following clause to complete the concession–conclusion meaning. Avoid ending at "AうがBうが, ...(trailing off)".
• Answer-choice traps: Wrong options often replace が with は/も/を or use "静かろうが" (wrong part of speech). Check the endings かろう/だろう/であろう and the 意向形.
