Hi,
I am working under 4 years contract in Tokyo as a developer. I can leave my company in one month notice. But I want to know that can I have any problems like COE or goverment laws or visa related problems .
Please answer if anybody know clearly.
Thanks.
If you have an Engineering visa, you’re allowed to change jobs as long as the visa hasn’t expired. You don’t need to renew it or change anything. If you want to be on the safe side, just call immigration about it.
Thank you 
. I hope I can change when I want.
