There occasionally are some prospective Business Manager’s Visa applicants who hardly know the basics of business administration in Japan.
One example is social security. Once a company is established, Employee’s Pension Insurance and Employee’s Health Insurance are mandatory. The company pays a half of the premium of each, and the employee pays the rest.
This is well-known among Japanese workers, but if you want to succeed in a business in Japan, knowing the basics of business administration is the must.
