Social Insurance System: Who Qualifies and What You Get
Understand how the mandatory social insurance contributions work for employees in Japan and what you need to watch out for during annual adjustments.
The Social Insurance System is a mandatory program designed to provide social security coverage for workers.
Who it's for
This system is for all full-time employees. It also includes qualifying part-time workers.
What you get
Participants make mandatory monthly contributions to the system. These costs are split, meaning your employer pays a portion and you pay a portion.
What it costs you
It costs you a portion of your monthly salary through automatic deductions. Your employer also covers a significant part of the total cost.
The catch to know
You need to be aware of the annual adjustment period known as 'shigetsu-henkou'. During this time, your standard monthly remuneration—the fixed amount used to calculate your premiums—is reviewed and adjusted.
How to apply
- Confirm your employment status with your employer to ensure you are enrolled.
- Review your monthly payslip to see the deductions made for your insurance.
- Monitor your salary changes to prepare for the annual adjustment period.
