At mailun-lab, we provide self-study materials designed to help you master business Japanese e-mails.
Our goal is not just to help you write "correct" Japanese, but to empower you to express your thoughts and intentions clearly through text.
In e-mails, where you cannot see the other person’s face, your choice of words is the only way to convey your feelings.
Building strong professional relationships is key to working smoothly in Japan.
To be honest, even for native Japanese speakers, this is a challenge.
So, please don't worry if you find it difficult at first.
At mailun-lab, we are here to support Japanese learners who struggle with e-mail writing. If you’re looking to improve your skills, please read on.
【Recommended for:】
- Those currently working at a Japanese company
- Those aspiring to work at a Japanese company
- Those who conduct business with Japanese partners
- Anyone looking to master business Japanese e-mails

"It takes way too much time to write an e-mail in Japanese."
"I’m so afraid of being rude that I’m scared to hit the 'send' button."
You are not alone. Many Japanese language learners face these exact same challenges.
In the Japanese business world, an e-mail is more than just a way to communicate—it is a vital tool for building "trust."
At mailun-lab, we offer materials designed to help you send e-mails with confidence.

Why Choose Our Materials?
While there are many Japanese business email resources available, here are three reasons why we highly recommend the materials from mailun-lab.
1.Created by a Japanese teacher with HR experience
Mailun-lab is run by a Japanese language teacher with a background in Human Resources.
During my time in HR, I was responsible for employee training and supporting international staff.
My teaching materials are built directly on that professional experience.
Furthermore, having worked in London and Frankfurt, I have also experienced being an "international employee" myself. I develop these resources by incorporating the specific insights and challenges I faced while working abroad.
2.Deep dive into the "Why" behind the rules
In my experience, I have noticed that many people know what they should do, but don't always understand why they need to do it.
That is why my materials focus on the reasoning behind Japanese business etiquette—explaining why Japanese people act the way they do and why certain approaches are preferred.
By providing insights into Japanese perspectives and values, I hope to help you act with a clear understanding of the underlying reasons and cultural background.
3.Access to practical, daily email samples
The "Textbook -応用編-" introduces phrases and expressions for various situations, allowing you to use them immediately in actual business emails.
In particular, the "Supplementary Materials -Practical Level-" (Practice 1–9) included in the Complete Pack feature approximately 30 email response samples.
These are based on the actual phrases and expressions I use in my professional life.
Because these materials are built on my firsthand experience, the content is exceptionally realistic.
