What do Japanese think about job-hopping?

Japan has a better pension system, which is provided by companies.

For an employee, as long as he does his best to the company, he will have a good pension when he is old.

Unlike Europe and America, social security is provided by society, so your job-hopping has no effect on your retirement. As long as you earn more, your life will be better in the future and society will provide returns.

In Japan, enterprises must be able to support these retired employees. Therefore, if employees want to get good treatment in the future, they must have good marketing ability, and their own interests are directly linked to the interests of enterprises. If the enterprise goes bankrupt, the rest of my life will be wasted, and I will be particularly loyal to the enterprise at will. Then you can imagine changing jobs.

I only know so much, and it seems to have something to do with her nationality. I don't know exactly.
