Bummer Tokyo Drew passed, I had heard of him and seem some content and did not know him. Interesting to hear that even for a Canadian health care is cheaper in Japan.
On costs yes it is much cheaper in Japan (except some things like fruit) but if cost is your motivation Thailand has in some people's view better medical care for cheaper and has a retirement visa. Malaysia also has a retirement visa. Japan does not. Still I think a rough off the cuff calculation I would need 60% of the money I'd need in the US so yes financial is significant of course wife's demand is the biggest but I like Japan and have the inlaw family support network. Wife is set on Japan a big nope on anywhere else.
One whom we posted about earlier and I know in person came back to the US as he wanted newer treatment than Japan had available so he came back to the US. No idea how he can afford it after retiring on yen doing his whole working life in Japan. Most people do not need some cutting edge treatment that is only available in US but that is something to keep in mind for some conditions.
This is not the first time I've seen black people say they feel safer in Japan, police won't shoot you for being well tanned in Japan.
I also agree with you young woman that strangers are more likely to help you in the US than Japan, also US volunteers more. However Japan you probably need less help.
As mdchachi mentioned earlier if you are a different color and born in Japan you are still treated as a foreigner, if you take citizenship you are still treated as a foreigner like our young high school friend.
Here is an American guy who moved from Japan to Thailand. He also interviews some Japanese who moved to Thailand. More friendly, cheaper, easier to get a place to live, no refusal of service etc. He says Thailand healthcare is even more welcoming than Japan.
For me personally Japan is better but I think for many it is not, I think most should explore options.
