There are 3 main labor laws in Japan that corporations need to take into account; the Labor Standards Law which sets the standards for working conditions, the Industrial Safety and Health Law which sets standards regarding health and safety and the Minimum Wage Law.
When a company reaches 10 employees or more, it is required to draft a set of work rules and submit them to the local Labor Standards Inspection Office. The work rules should be in line with Japanese Labor Standards and should cover details in regard to fundamental conditions such as working hours, salaries and termination. It is advised to consult the Labor Standards office in regard to the required content for a company work rules handbook.
When a company has hired 5 employees or more, social and labor insurance should be provided for all employees. The company should contact their local social insurance office and submit notification of the number of employees and other required information.
Employee contracts at minimum should contain details about the following employment conditions.
Probation periods are allowed to be specified in employee contracts and usually last for around 3 months, however if an employer refuses to grant full employment after the probation period has elapsed, it will be treated in the same manner as dismissal. Valid reasons for refusal of employment must be cited.
What is officially required of employers and what is expected of employers may differ on occasion so it is always good to be aware of the common work practices and expectations in Japan.
