Cornerstone Strategy LLC supports Japanese companies that are starting or expanding their business in the United States with the setup of their HR function.
To hire employees and operate a business in the United States, companies need to establish a wide range of HR foundations, including employment-related documents, employee handbooks, recruiting, onboarding and termination processes, payroll and benefits administration, HR vendors, and rules for employee relations and day-to-day HR operations.
We do not simply prepare documents or policies. We focus on building a practical HR structure that reflects U.S. laws, employment practices, and business customs, and that can be operated continuously by the local subsidiary.
Do You Face Challenges Like These?
- You plan to hire employees in the United States, but are not sure where to start.
- Your U.S. subsidiary does not have an HR representative, or its HR function is not yet fully established.
- Employment-related documents such as an Employee Handbook, offer letters, and HR policies are not yet in place.
- Processes for recruiting, onboarding, payroll, benefits, leave management, and termination are handled on an ad hoc or person-dependent basis.
- You have concerns about selecting vendors for payroll, benefits, insurance, HRIS, or other HR-related services.
- You are not sure how to adapt the HR policies of the Japanese headquarters to U.S. employment practices.
- Employee inquiries and workplace issues are being handled reactively as they arise.
- You need to establish the minimum HR foundation required to support business expansion.
Setting up an HR function in the United States requires more than assigning someone to HR or preparing basic documents.
It is important to design HR as a business-supporting function that integrates the full employee lifecycle, including hiring, day-to-day employee relations, payroll and benefits, compliance, and management support.
What Is HR Function Setup?

HR function setup is the process of establishing the human resources and employment management foundation needed to operate a business and manage employees appropriately in the United States.
This includes creating the practical HR infrastructure required for day-to-day business operations, such as employment-related documents, employee handbooks, recruiting and onboarding procedures, payroll and benefits administration, employee information management, leave management, performance-related processes, termination procedures, and HR vendor management.
For Japanese companies operating in the United States, it is especially important to respect the policies and management framework of the Japanese headquarters while adapting to U.S. employment practices, state-specific requirements, employee expectations, and local management realities.
Cornerstone Strategy LLC supports the setup of an HR function that can be practically operated, taking into account your company’s business stage, employee size, local management structure, and relationship with the Japanese headquarters.
