御中

1. Origins, structure, and basic meaning

• Structure: 御中 (おんちゅう) is a formal mailing honorific placed after the name of an organization or office.
• Basic usage: It addresses a company or secretariat when no individual recipient is named.

2. Common pitfalls and similar expressions

• For an organization, not a named person
  • Use 御中 after the organizational addressee; it is not the personal honorific appended to a specific employee's name.
