What kind of jobs are here in Japan that provide visa and that can be done 100% remote except IT?

Hi everyone! I've been working for 2,5 years in manufacturing (corporate sales) in Kanazawa. The company drives me crazy. It's been this long, but despite the range of my duties growing, I have yet to acquire any meaningful skills. I am already 30, and if I keep working here, I will not only waste more years of my life, but also I will probably just hang myself eventually.
However, I have no way to move to another city now, because I ① have no money for that, ② am planning to move with my boyfriend in about 3 years when he graduates and find his job.
He is Japanese and I initially thought to get my spouse visa then and finally be allowed to choose jobs that not necessary guarantee a visa. But my current workplace drives me nuts, makes me depressed and I've never felt so talantless and worthless as in this environment.
Thus, the question – what are the good ways to find a full-remote work that will guarantee me a visa, if the work is not IT-related?
P.S. My visa type is that shitty Designated Activities 46 that requires me to get an approval from Immigration bureau to even change my job.
