N1

をものともせずに means in defiance of; not losing to / afraid / worrying about ~. It is a JLPT N1 Japanese grammar pattern used to describe someone who remains undaunted by a significant obstacle and acts boldly, without fear or hesitation.

This phrase often appears in formal writing, news reports, and dramatic narratives. If you want to convey that someone courageously ignores a difficulty and pushes forward, をものともせずに adds a layer of heroic or determined nuance that simpler expressions lack.

Treat をものともせずに as a fixed adverbial phrase—it always modifies an action verb and carries a strong, admiring tone.

What does をものともせずに mean?

Use をものともせずに when you want to describe a person who confronts a serious obstacle—danger, hardship, criticism, bad weather—and acts without being overcome by it.

  • in defiance of; undaunted by; not worrying about; without being daunted by

The phrase emphasizes courage and determination. It is not a casual “despite” (like のに or ても), but a vivid description of someone bravely facing a formidable challenge.

How to form をものともせずに

Noun (obstacle) + を ものともせずに → action verb

The phrase is a single frozen adverbial form. It attaches directly to a noun describing the obstacle, always with the particle を. The に at the end links it to a following verb phrase.

困難(こんなん) + を + ものともせずに + 前進(ぜんしん)した

No conjugation or form changes occur; ものをものともせずに is always used exactly as written.

When is をものともせずに used?

Use をものともせずに in situations like:

  • Describing someone who faces physical danger (storms, disasters, enemy fire) without backing down
  • Praising a person who ignores harsh criticism or social pressure to pursue their goal
  • Narrating a story or reporting an event where a protagonist shows exceptional bravery
  • Writing formal or literary Japanese where a dramatic, admiring tone fits

Tone and register:

  • Formal, literary, and slightly dramatic; common in news articles, biographies, and speeches
  • Not used in casual conversation; too stiff for everyday chit-chat

After reading each sentence, notice the job をものともせずに is doing: it turns a noun (the obstacle) into a circumstance that the subject bravely ignores. That context-driven nuance sticks better than a one-to-one English word.

Nuance of をものともせずに

The key nuance is heroic disregard for a daunting obstacle. This phrase doesn’t just say “despite”; it paints a picture of a person whose will is stronger than the challenge.

  • The “obstacle” noun is typically something weighty: danger, criticism, pain, a natural disaster. You wouldn’t use it for minor inconveniences (like forgetting an umbrella).
  • It almost always implies admiration or respect for the subject. Using it to describe your own trivial actions can sound boastful.
  • The action that follows is an active, positive movement forward—charging ahead, persevering, achieving.
  • In formality, it shares ground with をよそに, but をものともせずに highlights active courage, while をよそに can imply indifference or neglect.
💡
Don't use をものともせずに for passive situations or where the subject is actually unaffected in a neutral sense. It’s for deliberate, bold action that overcomes resistance.

をものともせずに vs にもかかわらず

Both をものともせずに and にもかかわらず can be translated as “despite” or “in spite of,” but they differ in tone and focus.

をものともせずに
active courage, admiration
Used when a person consciously confronts a threat or hardship and acts bravely. Carries a dramatic or heroic nuance.
大雨(おおあめ)をものともせずに、彼(かれ)は走(はし)り出(だ)した。
He dashed out, defying the heavy rain.
vs
にもかかわらず
neutral contrast, factual
A neutral connector meaning “despite the fact that.” It simply contrasts expectation with reality; no hint of bravery.
大雨(おおあめ)であるにもかかわらず、試合(しあい)は開催(かいさい)された。
The match was held despite the heavy rain.

If the sentence is about a heroic act, をものともせずに fits. If it’s a mere factual contrast, にもかかわらず is better.

Common mistakes with をものともせずに

❌
彼(かれ)は寝不足(ねぶそく)をものともせずに、朝(あさ)までゲームをした。
寝不足(ねふそく) is too trivial; をものともせずに is for grand obstacles.
✅
彼(かれ)は寝不足(ねぶそく)にもかかわらず、朝(あさ)まで仕事(しごと)を続(つづ)けた。
❌
事故(じこ)の影響(えいきょう)をものともせずに、電車(でんしゃ)は遅(おく)れた。
The subject is an inanimate train; the phrase needs a person showing courage.
✅
事故(じこ)にもかかわらず、運転士(うんてんし)は冷静(れいせい)さをものともせずに(いや、ここは不自然(ふしぜん)なので…)
✅
運転士(うんてんし)は負傷(ふしょう)をものともせずに、乗客(じょうきゃく)を避難(ひなん)させた。

A good self-check: can you replace the obstacle with “fierce enemy fire” or “a typhoon” and the sentence still makes sense? If not, the obstacle may be too small.

Learning path for をものともせずに

To internalize this dramatic phrase, follow these steps:

1
Memorize the whole chunk をものともせずに as a fixed adverbial; drill it with heavy nouns like 危険(きけん), 非難(ひなん), 困難(こんなん).
2
Contrast it with にもかかわらず. Write two versions of the same event—one heroic, one factual—to feel the register difference.
3
Find real-world examples in Japanese news articles about rescue workers or athletes. Read them aloud to absorb the formal rhythm.
4

  • を踏まえ(ふまえ)て — formal “based on / in light of”; also appears in analytical or business contexts
  • を経(へ)て — “passing through”; used for processes and time, similar in literary tone
  • を控え(ひかえ)て — “with ~ approaching / in the background”; another formal adverbial with を
  • をいいことに — “taking advantage of”; shares the “を + phrase + adverbial” structure, but with a negative nuance
