Can Japanese workers change jobs in the second year of renewal?

You can jump ship.

If there is no big dispute, Yuan Company will not call the Immigration Bureau to cancel the visa. It doesn't matter if it is cancelled, just update it in the company.

It turns out that when the company handles it, it gives you a technical visa, which will reflect your work place and nature, because these are related to your future tax payment or the company's life guarantee in Japan.
