Thank you for the detailed answer. It was quite helpful. The money is from Japan, but since I own the company, I set it up in a way that my salary is quite low and the business pays for much of my expenses. This helps with my Japanese taxes. Ordinarily, income taxes very well might be higher here, but a give myself a low salary. Anyway, it ends up that going with the foreign earned income exclusion was best.
I will save your and @macuser_22 's replies for future reference. Btw, thanks also to @macuser_22 for your input!
