Okinawa is not about lemons, it is about occupying a foreign country.
US Americans are the only nation on earth who is naive enough to believe that occupied countries like their occupyers....

As for "where do you like to live?"
99,9999% of the people answering don't really KNOW more than some little information about this point on earth they think to be happy if living there. And the very rest of is wrongly extrapolating the "experience" of some weeks of holidays they had there as tourists - and are naive enough to think they have enough information to be capable to make a considrable choice....
As for me, I am an expat and live and WORK not far (Bout 1000 km) away from my own country, both are in Europe.
But even in between Europe you have enormous differences in culture and way of live, different infrastructures.
And so on. After about 12 years of living there I know well: the best place to live on earth is where your best friends Re living. Mostly, this is still in the country where you grew up and made friends for live.
Of course you make friends (I am talking about FRIENDS, not superficial people pretending to be your friends after a glass of wine or just people you know just a little bit, I am talking about REAL FRIENDS) in other countries. But your country was your country ans will stay so - in most cases. That is the reason why the vast majority of expats come back - sooner or later.
I am not an exception, I will do so as well.
I have to say I am amazed by the certainty with which you dismiss the perspectives of others, and the ease with which you choose to sit on judgement on their choices.
You don't know them, and nor can you know the sum of their lived life experiences.
Some of have posted here have undoubtedly worked abroad, lived abroad, studied abroad, as well as taken holidays abroad, and are more than perfectly capable of making such a choice for themselves. Some are introverts, and have less need of endless human interaction, while their friendships take place on a less perfervid plane, while others are extroverts and could not conceive of a life lived without their orbiting circle of friends.
Life abroad - working, and travelling, and the experiences you have there - may change you fairly fundamentally. You may find that your friends back home change in your absence, - or, acquire other compelling priorities, such as children and spouses - and that the shared past cannot substitute for, or compensate for, the looser ties of the present.
There was a time, over twenty years ago, when I saw a group of friends almost weekly. Their lives remained in my home town, mine moved to other cities, (work and study), and finally, other countries and continents, sometimes, for years at a time. Now, I may see some of them once a year. It is great to meet and catch up, but our lives have taken different directions. Now, if I were to meet them weekly, I fear I'd be bored out of my mind.
