Stuck in my home country and can’t return during my visa period. What are my options?

Hey guys,

Kind of a sob story. My little brother is disabled, my parents have now reached the point where they can no longer care for him.

I didn't realise how bad it was until I got back here, and everybody requires immediate care. I don't think I can return to Japan…

What are my options here? I love my life there, I love my job, but this is a situation I can't walk from. In terms of properly quitting my job and making sure everything is paid while I'm still in my home country, how do I go about this? Any other loose ends I can tie up while I'm here? Exemptions? I'm really at a loss and this is a lot to deal with.

Any help is welcome, thank you so much guys
