Those who have stayed in Japan for a long period of time as a permanent resident

I will be living in Japan for a while next year to take care of my mother who is in Japan, or I will be coming and going.
How often should I come and go for a short period of time to maintain my permanent residence
For a long period of time, I need to apply to USCIS by filling out a 1-131 form
I was wondering if anyone who has done this application in recent years, or if there is a lawyer with a reasonable fee, or any other
advice you can give me? 367> I would appreciate any advice you could give me.
