Western business emails start with the conclusion and are structured to be highly logical and sharp. Because of this, foreign professionals landing in Japan often feel a sense of discomfort with the constant repetition of “Otsukaresama desu” and “Yoroshiku onegaishimasu” in Japanese business emails, viewing them as “inefficient and meaningless customs.”
However, dismissing these phrases as mere “greetings” is a fatal mistake. In the Japanese business environment, these phrases are not emotional exchanges; they function as a “defensive protocol” to avoid unnecessary friction and safely maintain psychological distance between organizations. This article decodes the logical structure of this unique system and explains how elite professionals can practically utilize it to conduct business smoothly in Japan.
1. A System, Not a Greeting: The Standard Phrases
Japanese business emails are structured almost like HTML tags in programming, enclosing the main body with specific phrases.
The True Function of “Otsukaresama desu” (Authentication and Buffer)
This phrase does not mean “you are tired.” Its practical function is “proof of no hostility (authentication)” and a “buffer before getting to the main point.” Japanese businesspeople feel psychological resistance, perceiving it as “aggressive” or “cold,” if demands are thrust at them abruptly. Placing this at the beginning of an email is a system to instantly share the premise: “We belong to the same business community and respect each other’s efforts.”
The Function of “Yoroshiku onegaishimasu” (Contractual Closing)
This carries a different weight than the English “Best regards.” This phrase acts as a kind of contractual closing, implying: “Regarding the requirements presented in this email and our future relationship, we will complete the process on the premise of mutual cooperation.” Its presence establishes a balance of “obligation” between the sender and receiver, acting as the infrastructure that moves work forward.
2. The “Efficiency Trap” and Fatal Mistakes
If you prioritize logical efficiency too much and omit or misuse these protocols, you risk being marginalized in the Japanese business scene as an “untrustworthy partner.”
- Omitting Standard Phrases (Sending Only the Core Message): If you skip the standard phrases and send only bullet points to a Japanese client or partner, you will be mistakenly perceived as extremely “commanding.” Cases where project progress unintentionally stalls due to this are endless.
- The Hierarchy Trap: “Gokurosama desu”: Using “Gokurosama desu” instead of “Otsukaresama desu” is an absolute taboo. This is a phrase used by a superior to acknowledge a subordinate’s work. Using it towards a client or boss will severely offend them and risks immediately destroying the business relationship.
3. Practical Best Practices: Controlling Psychological Distance
From a different perspective, these standard phrases unique to Japanese emails are “highly efficient tools for eliminating emotional labor.”
In Western emails, you must carefully choose between “Dear,” “Hi,” “Hope you are well,” “Best,” and “Cheers” depending on your level of intimacy with the recipient. However, in Japanese business emails, whether it is someone you are meeting for the first time or a client of 10 years, you can always maintain a safe, professional distance simply by using the following sandwich structure:
- [Recipient’s Name/Title]
- Itsumo osewa ni natte orimasu. (External) / Otsukaresama desu. (Internal)
- [Logical Body / Core Message]
- Yoroshiku onegaishimasu.
Conclusion
“Otsukaresama desu” and “Yoroshiku onegaishimasu” are excellent firewalls that automatically prevent unnecessary interpersonal trouble within Japan’s unique and sometimes unforgiving infrastructure. Rather than dismissing them as an “inefficient culture,” mechanically incorporating them as “defensive tools” to safely execute your business is the optimal solution for elite professionals succeeding in Japan.
