TOKYO (AP) _ Japan's oldest person died Thursday at his home in northeastern Japan. He was 112.

Denzo Ishizaki, born October 20, 1886, died of multiple organ failure, his family said. He lived in the town of Kansago in Ibaraki prefecture, 78 miles northeast of Tokyo.

He briefly served as a town assembly member after retiring from a career as an elementary school teacher. His health deteriorated after injuring his hip in 1997, the family said.

The title of oldest Japanese is now held by Kamato Hongo, 111, of Kagoshima, 620 miles southwest of Tokyo, Kyodo News agency reported.

Ishizaki became the country's oldest person in February, when Yasu Akino died at age 113.

The Guinness Book of Records lists 118-year-old Sarah Knauss of Allentown, Pa., as the world's oldest person.
