Japanese Writing a Thank-You Email After an Interview: The O-rei Mail

What the o-rei mail is for

The purpose of the o-rei mail is modest: to thank the interviewer for their time, to confirm that you are still interested, and to show that you can write a correct, polite message. It is not a place to add arguments for hiring you, to ask about the result or to apologise for answers you think went badly.

The mail is written in business keigo throughout: humble forms for your own actions and respectful forms for theirs, plus the set phrases of Japanese email. If you are already comfortable with the general frame, company name and sama at the top, o-sewa ni natte orimasu, a body in short lines, and a signature block, you only need to learn the interview-specific content below.

Subject line, addressee and opening

The subject line, kenmei, must let a busy person see who you are and why you are writing without opening the mail. The standard pattern is the phrase mensetsu no o-rei, the date in brackets, and your full name. Some candidates add the position in brackets too. If the recruiter emailed you to arrange the interview, replying in that thread with the subject unchanged is also normal and makes the thread easy to find.

The first lines identify the reader and yourself. Write the company name in full, then the department, then the person's name with sama, each on its own line. For your own line, give the date of the interview, the position and your full name, using the humble phrase mensetsu o ukesasete itadakimashita, I was given the opportunity to be interviewed.

Thanking and mentioning one specific thing

The thanks itself is one sentence, and the standard version is above: o-isogashii naka, kichō na o-jikan o itadaki, makoto ni arigatō gozaimashita. What lifts a mail out of the pile is the next sentence, which refers to something you actually heard: a project the interviewer described, an explanation of the team's work, a comment about the company's plans. Keep it to one or two lines and connect it to your interest, not to your qualifications.

The verb for hearing from a superior is ukagau, and the pattern o-hanashi o ukagai, hearing your explanation, is the natural way to start this sentence. Words like miryoku o kanjimashita, I felt attracted to, and rikai ga fukamarimashita, my understanding deepened, are the accepted, slightly formal ways to say that something impressed you.

Restating interest and closing

After the specific line, restate your interest in one sentence and then close. The restating sentence uses shibō, aspiration to join, or the verb kōken, to contribute. Do not promise outcomes; say you would like to contribute, kōken shitai, rather than that you will succeed. Then ask for their consideration with go-kentō no hodo, yoroshiku onegai mōshiagemasu, and add a closing courtesy.

A common final touch is to say that a reply is unnecessary: go-henshin wa fuyō desu, or more softly, go-henshin ni wa oyobimasen. This is considerate because it tells a busy recruiter they need not answer, and it signals that you understand the mail is a courtesy rather than a request. End with a signature block: full name, and whichever of phone number and email address you gave on your application, so they can reach you.

A full template you can adapt

Here is the complete mail, line by line, for a full-time interview. Replace the company, department, name, date, position and the one specific line. Keep everything else. The lines are short on purpose: Japanese business mail breaks at natural phrase boundaries rather than filling the width of the screen.

Timing, format and when not to send

Timing is part of the message. Send within a few hours, during business hours if possible, and no later than the following morning. If two or more days have passed, the moment has gone; sending a late thank-you draws attention to the delay, so it is better not to send one at all.

Send from the same address you used to apply, in plain text, with no attachments, images or coloured fonts. If the company told you not to contact them, or the process is run entirely through a recruitment agency or a portal that discourages direct mail, follow that instruction: the agent can pass your thanks on. For a part-time job interview at a shop, a mail is welcome but less expected; a short one is enough.

• Same day, during working hours: best
• Next morning: fine
• Two days or more later: skip it
• Applied through an agency: thank the agent instead and let them relay it
• Group interview with several interviewers: address the recruiting contact, thank everyone in the body
• Online interview: same rules; you can mention the online format naturally

If the interviewer gave you a business card, the name and department on it are the ones to use in the address line. Check the spelling of the name against the card, not your memory.

Vocabulary for the o-rei mail

These words appear in nearly every thank-you mail. Learning them as a set makes the template feel like your own rather than something copied.

Mistakes that undo the good impression

The most damaging mistakes are the ones that change the tone. Asking about the result, kekka wa itsu wakarimasu ka, turns a thank-you into a demand. Apologising for weak answers, or adding an argument you forgot to make, turns it into a second interview. Its whole job is to be gracious and brief.

The second group is keigo slips: mixing onsha into writing, using arigatō gozaimasu in the present tense for a finished interview when arigatō gozaimashita is expected, writing the person's name without sama or with san, and doubling honorifics such as o-ukagai itashimashita. The third group is formatting: a vague subject line, a mail with no name in the first lines, long unbroken paragraphs, and an emoji or an exclamation mark anywhere. Read the mail once more against the template before you send it.
