Entering a contract U.S. job with a spouse who may potentially get a job in Japan.

My question is about me coming over to Japan at a later date and if that'll be an issue.

So the plan was always for him to get a job in Japan (potentially a HSW visa) and I'd be on dependent. Maybe I'd try to do p/t English teaching w/e.

However, I'm a graphic designer who does contract work. I know I cannot work remotely for a foreign company in Japan and especially not on a dependent visa.

The worry now is that he'll get a job in Japan before the contract is up. Are there any issues or situations where a spouse came over on a dependent visa potentially months after individual who got the working visa? Is this is a thing I have to worry about? Because if so, I'll have to decline the job and I'm not going to ask my husband to wait out his career.

Thanks in advance.

edit because I had a thought: I'm also a self published author and have had books out/royalties for over a decade. I'm always doing stuff with my books (audio recordings and potentially future ads because I've had a resurgence in popularity). Do I have to remove all my books upon moving to Japan under a dependent visa? I don't want this to bite me in the butt down the road, legally speaking.
