You need to create an OU in Active Directory. This is usually done to delegate control, GPO application, etc.
You can do this using Active Directory Users and Computers (ADUC)
- Log into a DC.
- Start ADUC.
- Navigate to the top-level of the domain.
- Navigate to the part of the tree where you wish to create the OU. We’ll create the OU under <domain>->Corp Sites in our example.
- Right-click Corp Sites and choose New->Organizational Unit.
- Name the Organizational Unit (OU). In our example, we’ll name it Japan.
- Click Ok.
- The OU has been created.
