$4000 a month, after taxes, is about $38,000 a year. Not a hell of a lot, esp when living overseas. $2000 a month is less that a full time Wal-mart employee. Basically YT income in the past doesn’t explain her ability to live and travel in Japan today because it was enough to live on, not save up so you could spend months traipsing around Japan on the cheap.
If there was a innocent explanation for her income and traveling instead of working, she wouldn’t be so tight lipped about it.
I did wonder if the travel could also be a way to renew her “tourist visa” with proof she is traveling around the country. I tend to think she’s going back and forth on a tourist visa while scheming for a husband/visa whatever she can manage.
