How to Write Business Emails in Japanese

Japanese business emails have a ceremonial element to them and because of that there is more of a templated formal structure than the freeform letters we are used to in a western context.

The first thing to remember when it comes to writing a Japanese business email is the use of the word「様」. This is an important and polite suffix/honorific that is standard procedure for Japanese business emails. (You can learn more about its uses in our post about Japanese Honorifics)

Other than that, always remember to express gratitude when you start your email.

You can use phrases such as「お世話になっております」which means “We become indebted to you” literally (in practice this is a formal greeting saying – thank you for your continued support or something close to it) or「お世話になります」which meants”thank you for your help“. After you open your email, you would need to introduce yourself. Introduce yourself by stating your full name and your current company you are working for with your current position.

If this is your first time meeting the person and you are doing a followup with the person, you may use this phrase「ABC株式会社のアダムと申します」which meant “this is Adam from ABC Corporation“. If this is not your first time meeting the person, you should use this phrase instead「ABC株式会社のアダムでございます」which also meant “this Adam from ABC Corporation“. Depending on the type of relationship of business you are writing to, there are 2 types of language forms.

Using Keigo in Japanese Business Emails

The first form is 尊敬語 (Sonkeigo) which is the honorific language. This form conveys courtesy and respect for the person you are writing to. This form can be used not only to your listeners but also to a third person as well. The only differences are from the polite form. Keep in mind that this form is usually too formal and instead, the humble form is used more often.

As for the second form, it would be 謙譲語 (kenjougo) which means humble form. This form is used when you want to show your respect to the person you writing to of your actions by humbling yourself.

This step is very important as you would need to show your respect to the recipient. Thus, you would need to be very careful about which language forms to use.

The email consist of 7 parts.

  • Receiver: 宛名・あてな・Atena
  • Greetings: 挨拶・あいさつ・Aisatsu
  • Addressing yourself: 名乗り・のり・Nanori
  • Main body context: 要旨・ようし・Youshi
  • Details: 詳細・しょうさい・Shousai
  • Closing remarks: 結びの言葉・むすびのことば・Musubinokotoba
  • Name and Signature: 署名・しょめい・Shomui

If the two parties already have a close relationship, they can both leave some parts out. However, a word of caution that this would make the email less formal and more casual.
