TOKYO (Reuters) - Suekiku Miyanaga, Japan's oldest person, celebrated her 114th birthday on Tuesday. At her birthday party at a nursing home in Kagoshima on Japan's southern main island of Kyushu, Miyanaga cut her birthday cake and received a bouquet of flowers from the local government. The mother of four sons and seven girls, Miyanaga became Japan's oldest living person last May when a 113- -year-old woman died. Born in 1884 in Kagoshima, Miyanaga married at the age of 24. In a report released in September, the Welfare Ministry said Japan had 8,491 people aged 100 or older and 6,921 of them, or 81.5 percent, of them were women. According to the Guiness Book of World Records, the world's oldest person who ever lived was J. L. Calment of France. She died on August 4, 1997, at the age of 122.
