Questions on feasibility of moving to Japan

Hi.

So im currently 37 living in UK and working a Job in purchasing for the last 12 years that may be coming to an end.

Got me thinking about things I wish I had done at a younger age, one of those was to move to Japan.

Been on 3 occaaions before the longest period being 4 months.

I dont have a degree so given I would have to study on distance learning im looking at mid 40s by time I achieve that.

So what are the chances for an older person teaching or finding work in Japan?

Or does my work experience count for anything?

Really wish I hadnt left it so long, but you know, life happens I guess.

Feasibility would be low. But if it is something you really wanna do, go for it.

Thought this may be the instance.
Assume teachers in 40s are somewhat unattractive.

Well im seriously considering distance study regardless. So might be looking then anyway .

Unless there are any other options for living in japan Ive not considered?
