Well, if you really wanted to live here in Japan, you'd feel it pulling on your heart by now. I will warn you though that for me and many others, after living and working here for 2 years, moving back to America was a very painful experience, almost like the escaped slave from Plato's cave. People would ask me what it was like living in Japan, and after a while I realized it was best to just tell them "it was a life-changing experience" and leave it at that because how I would tend to answer the question would bore most people. For 10 years, I felt like there was a part of me I left behind. When I would return to visit once a year, I felt reunited with that part of me that stayed behind, and I felt whole for a few weeks. Then I'd return to the land of blubber butts, tattooed skanks, cretins, and people in line at the supermarket's register and complain to anyone within earshot about how slow the line is going.

In America, I worked overtime on evenings and sometimes weekends as necessary. Here in Japan, people stay late to appear busy because it's expected of them. As a teacher in Japan I'm exempt from that virtue signalling, but I did work for a company for about 8 months and I had the pleasure of sitting at my desk until at least 6:30pm pretending to look busy, even though there wasn't anything that couldn't wait until the next day, just to make the bosshole happy.

I've no idea if the work you do now cannot be done by a Japanese citizen, but know that unlike most of Asia, Japanese can't speak English worth crap as it is regarded more of a hobby than an actual means of communication. It's not like Singapore or Philippines where everyone speaks English. This can lead to some serious isolation issues. If you have questions about stuff, you can contact me directly.
