Advice for best path forward for me? (Heritage visa and work)

Hey guys, basically looking for advice on my best path forward to moving my career to Japan.

I am currently employed in the US and am in my late 20s. I have a good job in software engineering that is stable and the money is good. Its hard to leave that behind.

But I really want to travel to Japan and try to live/work there for the life experience. I would probably test and pass N3, and I know the culture well.

I can get the heritage visa. I've been applying to some companies on LinkedIn without the visa and have gotten 0 responses.

Should I get the visa and then start applying and move over if I get a job? Should I go there and work part time on savings and apply while living there? Any suggestions on how to not totally ruin my career but also work in Japan? Is the tech market as fucked in Japan as it is in the USA?

I don't care about money that much, I know the pay will be much lower, but if possible I'd love to remain in tech/engineering.

Any advice is appreciated.
