Yes - I'm enjoying life in the US right now. Great convenience, great weather, close to family, lots of things to explore, great environment for building a career, almost luxurious living space compared to Japan. I'm looking out my window at some greenery and a pool - going to see a movie later. Its a good life here in the States for me now.
But the crime situation here is a constant drain on mental energy. The healthcare system is abysmal. Public transportation is horrible. These are real weights that tip the scale in Japan's favor. I'm not in a high crime area, but every time you park the car you have to consider the possibility it could get broken into. Every trip into the big city is a lesson in public policy failure: freeway underpasses that have become homeless encampments, infrastructure wrapped in razor wire because if it isn't, it will get broken into, and every bus stop is a temporary shelter for drug addicts or the mentally ill.
For now, all things considered, the scale is still tipped in favor of the US for me and Mrs. Majestic. She doesn't like the heat and humidity of Japan, so she is totally happy here. She has also made many friends here. But I'd consider moving back to Japan if things changed.
I'm intrigued by these people who moved to Japan and are living in remote areas. I wonder if they don't feel any sense of isolation or inconvenience? I would love to live for a few months on an island off of Hiroshima, or some rural place in Shikoku...but I think I'd worry about things like access to dental care, and having a variety of shops and restaurants around me. And, I'd like to be anonymous every now and again - which you can't do when you are a foreigner living in rural Japan.
And the family that lives in Tokyo...theirs is a very rarified existence, enabled by the wife's access to long-term residency through her Japanese grandparents, and their income which enables them to live in the middle of Tokyo in a 600,000/month apartment.
