The remote Japanese island is one of three isolated communities in which last night's Horizon: How to Live to 101 focussed on.
The places were chosen because they appear to have stumbled across the answer to longevity, with many of the residents living to a ripe old age, virtually unheard of in other parts of the world.

The Californian town of Loma Linda and the mountains of Sardinia were the other two places - and from these communities we met Dr Ellsworth, a 92-year-old full-time heart surgeon; Marge Detton, who was enjoying a six-mile bike ride before deciding how to celebrate her 103rd birthday; and 92-year-old Mr Miyagi who had just taken up a new job as a karaoke teacher.
But don't make the mistake of thinking these people had limped into ultra old-age on their last legs - they all looked like they were having a whale of a time, and seemed at least 20 years younger than their true age.
Teams of scientists have dedicated their lives to finding out what it is these places have in common which allows the residents to have such long and healthy lives, which proved fascinating stuff.
So what was the answer? How do you live to be 101?
It seemed there was no easy answer, but my conclusion is that we'd all be better ditching the multi-vitamins and five-a-day regime, and instead start saving for a plane ticket.
