The four parts
A formal apology has a structure, and each part does a different job. Learners typically write the first part well and the last two thinly, which produces a letter that sounds sincere and satisfies nobody.
The reader is looking for the fourth part. What are you going to do so that this does not happen again is the question the letter exists to answer.
| Part | Japanese | Purpose |
|---|---|---|
| Apology | お詫び | State it plainly, first |
| Facts | 経緯 | What happened, factually |
| Cause | 原因 | Why it happened |
| Prevention | 再発防止策 | What will change |
| Closing apology | 重ねてお詫び | Repeat it briefly |
The apology appears twice: once at the start and once at the close. That repetition is conventional and expected.
Opening with the apology
The letter opens with the apology, not with background. Making the reader work through an explanation before reaching the apology is read badly.
The register is heavier than ordinary business correspondence, with humble forms used throughout.
| Japanese | Romaji | Meaning |
|---|---|---|
| このたびは、ご迷惑をおかけし、誠に申し訳ございません。 | Kono tabi wa, gomeiwaku o okake shi, makoto ni mōshiwake gozaimasen. | I am truly sorry for the trouble caused. |
| 深くお詫び申し上げます。 | Fukaku owabi mōshiagemasu. | I offer my deepest apologies. |
| 多大なるご迷惑をおかけいたしました。 | Tadai naru gomeiwaku o okake itashimashita. | We have caused you considerable trouble. |
| 弁解の余地もございません。 | Benkai no yochi mo gozaimasen. | There is no room for excuses. |
| 心よりお詫び申し上げます。 | Kokoro yori owabi mōshiagemasu. | I apologise from the heart. |
| ご不安をおかけしましたこと、お詫びいたします。 | Fuan o okake shimashita koto, owabi itashimasu. | I apologise for the worry caused. |
The facts, without defending
The account of what happened should be factual, chronological and brief. This is the section where an apology most easily goes wrong, because an explanation and a defence look similar on the page.
The test is whether a sentence tells the reader what occurred or tells them why it was not really your fault. The second kind should be removed.
| Japanese | Romaji | Meaning |
|---|---|---|
| 経緯をご説明いたします。 | Keii o gosetsumei itashimasu. | I will explain what happened. |
| 三月十日、納品に遅れが生じました。 | Sangatsu tōka, nōhin ni okure ga shōjimashita. | On 10 March, a delivery delay occurred. |
| 確認が不十分でございました。 | Kakunin ga fujūbun de gozaimashita. | Our checking was insufficient. |
| 社内の連携が取れておりませんでした。 | Shanai no renkei ga torete orimasen deshita. | Internal coordination was lacking. |
| 私の確認不足によるものです。 | Watashi no kakunin busoku ni yoru mono desu. | This was due to my insufficient checking. |
| 結果として、ご迷惑をおかけしました。 | Kekka to shite, gomeiwaku o okake shimashita. | As a result, we caused you trouble. |
Notice that these accept responsibility rather than distribute it. Naming a colleague or a supplier as the cause is poorly received even when accurate.
Prevention, which carries the weight
This is the section the reader wants and the one that makes the difference between an apology that closes a matter and one that does not.
Measures should be concrete and checkable. A promise to be more careful is not a measure; a changed process is.
| Japanese | Romaji | Meaning |
|---|---|---|
| 再発防止策を以下のとおり定めました。 | Saihatsu bōshi-saku o ika no tōri sadamemashita. | We have set the following preventive measures. |
| 確認手順を二重化いたします。 | Kakunin tejun o nijūka itashimasu. | We will double-check at each step. |
| 担当者を二名体制といたします。 | Tantōsha o nimei taisei to itashimasu. | We will assign two people to the task. |
| チェックリストを新たに作成しました。 | Chekkurisuto o arata ni sakusei shimashita. | We have created a new checklist. |
| 社内で共有し、周知いたしました。 | Shanai de kyōyū shi, shūchi itashimashita. | We have shared and communicated this internally. |
| 今後このようなことがないよう努めます。 | Kongo kono yō na koto ga nai yō tsutomemasu. | We will work to ensure this does not recur. |
Written or spoken
Most apologies are spoken and immediate. A written apology follows where the matter is serious, where a client is affected, or where a record of the measures is wanted.
For a serious matter the order is usually spoken first and written afterwards, since a written apology arriving before any contact reads as avoidance.
| Situation | Spoken | Written |
|---|---|---|
| Small internal mistake | Yes | No |
| Missed internal deadline | Yes | Sometimes |
| Client affected | Yes, first | Yes, after |
| Financial loss caused | Yes, first | Yes, formal |
| Repeated problem | Yes | Yes, with measures |
Where both are needed, speak first. A letter that arrives before any human contact is read as hiding rather than apologising.
Timing and tone
Promptness matters more than polish. An apology sent the same day in imperfect Japanese is received far better than a well-crafted one sent a week later.
Tone should be plain rather than dramatic. Over-elaborate expressions of regret can read as performance, and the conventional phrases exist precisely so that you do not have to invent language for this.
- Send it the same day where possible.
- Use the conventional phrases rather than inventing your own.
- Keep it to one page; length is not sincerity.
- Include at least one concrete measure.
- Have a colleague check it if the matter is serious.
