Do you know what to write before you get to the point in a Japanese email? Why does every message seem to open with the same line? And how much politeness is too much when you are the one asking?
Short answer: The Japanese Business Email Writer is a free EizTools tool that drafts business email in Japanese, handling keigo levels, the standard opening greeting, company and name order, and a closing that matches your relationship.
What is Japanese Business Email Writer?
Japanese business mail follows a shape. You name the recipient and their company, you open with a set greeting, you introduce yourself, and only then do you say what you want. The Japanese Business Email Writer builds that shape for you from a plain English brief, so the politeness layer is handled while you concentrate on the request itself.
Keigo And The First Line
Keigo is the honorific system, and it decides how every verb in your email appears. There is language that raises the other person, language that lowers you, and plain polite language for everything in between. Choosing the wrong level is not a small error, since it signals what you think the relationship is.
The opening line does similar work. Osewa ni natte orimasu to an existing contact, or hajimemashite when you have never written before, tells the reader immediately where they stand with you. Skipping it and starting with your request reads as abrupt even when the request is reasonable.
Read before sending Company names, titles and honorifics must be correct. Check that san, sama and the company suffix match what the recipient actually uses, since the tool follows whatever you type in the prompt.
How Does Japanese Business Email Writer Work?
Describe the email in the prompt box: who it goes to, your relationship, the request, and any dates. State that you want Japanese output and say how formal it should be. Choose an AI model, decide the options that matter here, then generate.
The output card carries your draft, with a word count and an estimated reading time attached. Take a copy for your mail client, save a Word or plain text version, or hear it through Listen, which helps if you are also learning to speak the phrasing. Every draft from the session stays in the activity history panel, so you can compare two versions before choosing one.
Setting Tone, Purpose And Warmth
| Option | Effect on the draft | Suggested start |
|---|---|---|
| Tone | How high the politeness level sits | Formal for clients, Professional inside a team |
| Purpose | The shape of the body text | Ask, Follow-up, Thank You or Announcement |
| Subject Line | How the subject is framed | Simple, since Japanese subjects stay factual |
| Warmth | How personal the wording feels | 30 to 40, higher only with close colleagues |
The switches decide what furniture the email carries:
- Include Greeting on, since the opening line is expected rather than decorative
- Include Signature on, because the closing block carries your company and role
- Include P.S. off, as it has no real place in Japanese business mail
Common Mistakes
Over polite to a teammate
Maximum keigo inside your own team can read as distance or sarcasm. Professional tone is usually right.
Burying the request
Politeness comes first, but the ask still needs to be findable. Keep it in its own short paragraph.
Wrong name order
Company, then department, then name. Getting that sequence backwards is the most visible mistake in the header.
The tools on EizTools each keep their own prompt box, their own switches and no sign up wall. You choose the model before generating and can regenerate as often as you like. If your message is an apology rather than a request, the Apology Email Writer starts from a better structure.
Frequently Asked Questions
Can I write the brief in English?
Yes. Explain the situation in English and ask for a Japanese email. The tool rebuilds the message using Japanese conventions rather than translating your English sentences one by one.
Does it handle keigo correctly?
It follows the politeness level you set through Tone and any notes in Custom Instructions. Read the result if the recipient is senior, since keigo carries real weight in those messages.
Is the Japanese Business Email Writer free?
Yes. There is no login step, no credit meter, no cap counted per day. You can draft the same email several ways, then download whichever version reads best as TXT, Word or HTML.
Will it include the standard opening greeting?
Yes, when Include Greeting is on. Say whether this is a first contact or an existing relationship, because the opening line differs and the tool follows what you tell it.
Can I get a romaji version too?
Yes. Ask for the Japanese text plus a romaji reading in Custom Instructions. Learners often generate both so they can read the message aloud while checking the characters against the original.
Japanese business email rewards structure more than vocabulary. Once the greeting, the self introduction and the closing are in place, a clear and modest request does the rest of the work. Write your brief, set the politeness level honestly, and check the names in the header before you send it.
