There has been the world longest life people in Okinawa. But inhabitants in Okinawa are thought that they have low mineral born and their born are weak. Because in Okinawa a rate of born fracture is high. Though people in Okinawa have the longest life all over the world, they are not healthy if their born will be broken. We investigated Osteo Sono Index (OSI) of habitants at 5 islands, Hateruma-jima. Kohama-jima, Iriomote-jima, Taketomi-jima, Kuro-sima, in Okinawa. There 5 islands have had less immigrants and emigrants. So they have a time-honored custom of life and food. This study revealed following things. Average of OSI varied with the distinction of sex and that did not do with any islansd. The more people aged, the more their OSI and Z score of OSI are reduced. Born fracture were mainly caused by sports, stumbling over, violent falls with bikes and motor bikes, and falls from high places including roofs. But born fracture of aged people who had been over 50 years old were caused by over, violent falls with bikes and motor bikes. A rare reason of born fracture was to be attacked by a water buffalo. There was no differences within a group of fractured born and a group of no fracturing. So born fracture were caused by some environment and not by reduced OSI.
