# こととて: because; since ~ > Learn how to use こととて, a JLPT N1 Japanese grammar point meaning because/since, with structure, nuance, examples, mistakes, and comparisons. JLPT level: N1 · Updated: 2026-05-18 · Canonical: https://hane-app.com/blog/n1-koto-tote/ **こととて** means **because; since ~**. It is a **JLPT N1** Japanese grammar pattern used to state a reason, often in formal or apologetic contexts, implying that the result is unavoidable given the situation. This grammar point frequently appears in formal letters, business apologies, and JLPT N1 reading comprehension. If you want to give a polite reason for an outcome, especially when asking for understanding, **こととて** is a useful pattern to learn because it adds a measured, respectful tone to your Japanese. ## What does こととて mean? Use **こととて** when you want to explain that something happened (or will happen) **because** of a certain situation, with an undertone of “it can’t be helped” or “I hope you’ll understand.” It’s a formal, slightly old-fashioned way of saying “since.” Natural translations include: - because; since; owing to; due to the fact that ~ The best translation depends on the sentence. Try to notice the writer’s or speaker’s purpose first, then choose the English phrase that fits that context. ## How to form こととて
V(plain) + こととて
い-Adj(plain) + こととて
な-Adj + な + こととて
Noun + の + こととて
Examples of the pattern: - 知ら(しら)なかった**こととて** - 忙しい(いそがしい)**こととて** - 突然(とつぜん)**のこととて** The form before the grammar point matters. In JLPT questions, the wrong answer choices often use a similar meaning but attach it to the wrong type of word. ## When is こととて used? Use **こととて** in situations like: - making a formal apology or excuse (especially in letters or official announcements) - explaining an unavoidable shortcoming or mistake - humbly asking for understanding, often in set phrases like **“不慣れ(ふなれ)なこととて”** or **“若輩(じゃくはい)のこととて”** Tone and register: - formal, somewhat literary or old-fashioned - more common in written language than casual speech - frequent in JLPT N1 reading passages and formal expressions ## こととて example sentences

After reading each sentence, ask what job **こととて** is doing: stating a reason while humbly asking for understanding. That makes the nuance easier to remember than a one-word translation. ## Nuance of こととて The key nuance is **a reason given in a formal, sometimes apologetic, tone, often implying the outcome was unavoidable**. This matters because learners often translate advanced grammar too literally. A pattern may look simple, but it can signal the writer’s attitude, the scope of a rule, or the relationship between two ideas. For example: - In a business email, **“不慣れ(ふなれ)なこととて”** sounds far more polished and respectful than a simple **“慣れ(なれ)ていないから”**. - It almost always appears in explanations where the speaker wants to soften criticism or excuse a failure. - Compared with **から** or **ので**, it carries a heavier, more deferential weight. ## こととて vs ことだから Both **こととて** and **ことだから** can express related ideas, but they are different.
こととて
because of the situation; since it’s the case (formal, often apologetic)
Used when explaining an outcome that stems from a circumstance, often to excuse a shortcoming. Formal letters, apologies, and written requests.
忙しいこととて、ご連絡(れんらく)が遅(ち)れました。
Since I’ve been busy, my reply is late (I apologize).
ことだから
knowing the person/situation as we do; because it’s typical of ~
Used when the reason is based on the known character, trait, or typical behavior of someone. More conversational than こととて.
彼(かれ)のことだから、また忘(わすれ)れてるよ。
Knowing him, he’s probably forgotten again.
Quick contrast: - **こととて** focuses on the **circumstance** (“since it’s been busy…” → apology). - **ことだから** focuses on the **person** (“knowing her…” → prediction or excuse). If both translations seem possible, check the tone. Is the sentence formal or casual? Is the reason an external situation or an inner character trait? The tone often tells you which grammar point is natural. ## Common mistakes with こととて Watch out for these mistakes: - Using it in casual conversation — it sounds overly stiff and can come across as sarcastic or unnatural. - Translating it simply as “because” without the apologetic nuance, missing the humble tone. - Forgetting the **の** with nouns (saying “*忙しい(いそがしい)こととて” is fine, but “*突然(とつぜん)こととて” is wrong; it must be “突然(とつぜん)**のこととて**”). - Treating it as a direct replacement for **から** in any sentence; without the excuse/understanding context, it feels forced.
❌
雨(あめ)が降(こう)っていることとて、傘(かさ)を持(もち)っていこう。
✅
雨(あめ)が降(こう)っているから、傘(かさ)を持(もち)っていこう。
Simple factual reason — no need for the formal, apologetic tone of こととて. から is natural.
❌
昨日(きのう)こととて、休(きゅう)みました。
✅
昨日(きのう)は当日(とうじつ)のこととて、急(きゅう)に休(きゅう)むことになりました。
Nouns need の before こととて. The corrected version embeds the reason in a situation.
A helpful practice method is to write one sentence with **こととて**, then rewrite it with **から** and **ので**. Ask yourself why you would choose the formal version — that clarifies the register. ## Is こととて on the JLPT?
N1

Yes. こととて is commonly taught as JLPT N1 grammar.

Expect questions that ask you to select the most appropriate pattern for a business letter or a humble explanation. Look for surrounding words like 不慣れ(ふなれ), 若輩(じゃくはい), 突然(とつぜん), or polite endings (～ます、～ございます).

For test preparation, study the grammar point in full sentences. JLPT questions often test whether you understand the surrounding context, not just the dictionary meaning. ## Practice questions for こととて
