Job hunting from overseas

hello!
I'm currently job hunting in Japan, but at the moment I'm still in my home country. I’ve noticed that almost every listing requires candidates to “reside in Japan.” Do you think this is a very strict condition, or are they sometimes flexible about it? Have you ever managed to find a job while applying from abroad?

I can’t enter again as a student since I already had a student visa about 10 years ago, but life brought me back to my country.
I’m 43 now, so it really feels like now or never and I gave me one year from now to do it!

Ps: reposted since I chose the wrong tag before!
