If you have ever stared at a blank screen, wondering if your Japanese email sounds “too cold” or “awkwardly over-polite,” you aren’t alone. Even for those of us who have spent years studying for the JLPT N2 or N1, the transition from textbook Japanese to the living, breathing world of Keigo (honorific language) in a corporate inbox is a daunting leap.
In my years of teaching Japanese and working with international firms in Tokyo, I’ve seen brilliant professionals lose deals or miss connections simply because they missed the “vibe” of a professional greeting. In Japan, an email isn’t just a carrier of information; it’s a digital bow. It sets the temperature of the entire relationship.
In this deep dive, we are going to deconstruct Japanese Business Email Greetings so you can write with the confidence of a native speaker. We’ll cover why certain phrases are non-negotiable, how to adapt your style to your recipient, and the subtle nuances that textbooks often skip.
Before we dive into the specifics, if you are looking for a comprehensive resource, be sure to check out The Ultimate Guide to Business Japanese Email Templates (With Real Examples & Free Downloads).
Why Greetings Matter More in Japan Than Anywhere Else
In Western business culture, brevity is often seen as a sign of respect for the other person’s time. We jump straight to “Hi [Name], hope you’re well.” In Japan, jumping straight to the point (Hondai) without a proper greeting (Aisatsu) can be perceived as abrupt, or even rude.
The greeting serves as a “buffer.” It acknowledges the existing relationship and shows that you understand your place within the professional hierarchy. Whether you are dealing with a long-term client or a first-time contact, your opening sets the stage.
For a broader look at the cultural nuances involved, I highly recommend reading up on Japanese Email Etiquette: The Do’s and Don’ts of Professional Communication.
The Anatomy of the Opening: More Than Just “Hello”
The opening of a Japanese business email is structured like a three-story building: The Company/Name, the Formal Greeting, and the Personal/Contextual Greeting.
1. The Recipient’s Information
Always start with the company name, department, and the recipient’s title and name.
- Format: [Company Name] + [Department] + [Title] + [Name] + [Sama]
Expert Tip: Never use “San” for a client or a superior in a formal email; “Sama” is the standard. If you are writing to a group, use Gochu (御中).
2. The Universal Opener: Osewa ni natte orimasu
If you learn only one phrase in your life, let it be “Osewa ni natte orimasu” (お世話になっております).
Roughly translated, it means “Thank you for your ongoing support/favor.” It is the Swiss Army knife of Japanese Business Email Greetings.
- When to use it: With any external contact you have interacted with before.
- The Variation: If they are a particularly important client or you haven’t spoken in a while, use Itsumo taihen osewa ni natte orimasu (いつも大変お世話になっております).
3. The First-Time Greeting
If you are cold-emailing or contacting someone for the first time, “Osewa ni natte orimasu” is technically incorrect because there is no “ongoing” relationship yet. Instead, use:
- Hajimete renraku sasete itadakimasu (初めて連絡させていただきます) – “I am contacting you for the first time.”
- Totsuzen no mairu nite shitsurei itashimasu (突然のメールにて失礼いたします) – “Please excuse me for contacting you out of the blue via email.”

Navigating Internal vs. External Greetings
A common mistake I see among JLPT N3 and N4 learners is using “Osewa ni natte orimasu” for their own colleagues. In a Japanese company, there is a clear line between Uchi (inside) and Soto (outside).
For Colleagues (Internal):
- Otsukaresama desu (お疲れ様です): This is the standard. Whether it’s 9 AM or 6 PM, this acknowledges their hard work.
- Ohayou gozaimasu (おはようございます): Only used for the very first communication of the day.
For Clients (External):
- Always stick to the formal Osewa ni natte orimasu variants.

The Body Transition: Getting Down to Business
Once the greeting is out of the way, you need a “bridge” phrase to start the actual content. You can’t just start a new paragraph with “I want to buy X.” Use these transitions:
- Sate… (さて): “Now…” (Use this to pivot to the main topic).
- Honjitsu wa, [Topic] no ken de renraku itashimashita (本日は、[トピック]の件で連絡いたしました): “Today, I am contacting you regarding [Topic].”
If you are writing about a specific property or a niche industry, your transitions might need to be even more specific. For instance, in the real estate sector, you would use phrases found in Property Inquiry Email Templates in Japanese: Polite & Effective Examples.
The Art of the Closing (Musubi)
In English, we have “Sincerely” or “Best regards.” In Japanese, the closing is often a request for future kindness.
1. The Standard Closing
Yoroshiku onegaishimasu (よろしくお願いします).
In a business context, you should upgrade this to:
Kongo tomo nani sotsu yoroshiku moshiaagemasu (今後とも何卒よろしくお願い申し上げます).
2. The “Response-Wait” Closing
If you are waiting for an answer:
Oisogashii tokoro osoreirimasu ga, go-kento no hodo yoroshiku onegaishimasu (お忙しいところ恐れ入りますが、ご検討のほどよろしくお願いします) — “I apologize for troubling you while you are busy, but I appreciate your consideration.”
3. The “No Reply Needed” Closing
To be extra polite when sending a simple notification:
Go-kakunin itadakereba saiwai desu. Na-o, go-henshin wa fuyo desu. (ご確認いただければ幸いです。なお、ご返信は不要です。) — “I would be grateful if you could check this. Furthermore, no reply is necessary.”

Expert Insights: The Subtle Nuances of “Keigo”
As a JLPT expert, I often tell my students that Keigo isn’t about making things complicated; it’s about “distance.”
- Sonkeigo (Respectful): Elevates the other person (their actions, their company).
- Kenjougo (Humble): Lowers yourself (your actions, your company).
When you use Japanese Business Email Greetings, you are almost always using a mix of both. For example, when you say “Moushiagemasu” instead of “Iimasu,” you are using humble language to show that your “speaking” is lower than their “listening.”
If you are in sales, this balance is even more critical. Using the wrong level of humility can make you seem arrogant or, conversely, weak. I suggest looking at Business Sales Email Templates for Japanese Clients (High‑Response Examples) to see how pros balance these two scales.
Practical Application: Real-World Scenarios
Let’s look at how this applies in specific industries. If you work in real estate, your greetings need to convey reliability and formality.
- Scenario A: Cold Lead follow-up. You wouldn’t just say “Did you see the house?” You would start with an acknowledgement of their time.
- Scenario B: Commercial Conversion.When dealing with high-stakes commercial deals, the greeting must be impeccable to establish authority.
Using Outbound Resources for Mastery
To truly master the flow, it helps to see how Japanese organizations like JETRO (Japan External Trade Organization) structure their communications. You can find excellent official guidelines on JETRO’s Business Manners Page which provides a high-level view of corporate expectations in Japan.
Another great place to practice your reading of formal Japanese is the NHK News Web Easy, which, while simplified, often uses the same polite structures you’ll find in daily emails.
Common Mistakes to Avoid
- Over-using “Sumimasen”: In an email, “Sumimasen” is too casual. Use “Moushiwake gozaimasen” for apologies or “Osoreirimasu” for “excuse me/thank you.”
- Using “I” (Watashi) too much: In Japanese, the subject is often omitted. Repeatedly saying “Watashi wa” makes the email sound self-centered.
- Forgetting the Seasonal Greeting: While not mandatory in every email, mentioning the heat in August or the cold in January in the second line of your email is a “pro move” that shows high-level cultural fluency.
