Born in 1897, the year of Queen Victoria’s Diamond Jubilee, he was 6 years old when the Wright Brothers showed the world that man can fly, and 11 when Henry Ford introduced the Model T automobile. He lived through two world wars, the reigns of four emperors, the terms of 20 U.S. presidents, and 61 Japanese prime ministers.  He had five kids, 14 grandchildren, 25 great-grandchildren, and 13 great-great-grandchildren,

Japan has the world’s highest life expectancy, and it’s bound to go up. Per WSJ, The life expectacy is projected to exceed 90 for Japanese women by 2050.
