Asa Takii, Japan's oldest person and a survivor of the Hiroshima atomic bomb blast, died today. Her 114 years spanned almost all of Japan's history as a modern nation.

Takii, born in Hiroshima April 28, 1884, died of heart complications from high blood pressure in a nursing home on the island of Kurahashi, 420 miles southwest of Tokyo, the nursing home's director said.Takii witnessed her country's rise as an imperial power, its crushing defeat in World War II and its resurgence as the world's second-largest economy.

She lived in Hiroshima on Aug. 6, 1945, when the United States dropped the world's first atomic bomb. The blast killed her husband and family and buried her in the rubble of her home until she was found days later.

She kept her memories of the war to herself, said Kumiko Nishiki, director of Tachibana-en nursing home where Takii died.
