The oldest man in Japan, 111-year-old Nijiro Tokuda, has died, officials said Tuesday.

Tokuda, of Kagoshima in southern Japan, died Monday night at a hospital where he had been treated since April, Kagoshima City official Masayuki Nagahama said.

The official said the city would not disclose the cause of death.

Tokuda had just celebrated his 111th birthday on Saturday.

Japan's oldest person is a 113-year-old woman, Yone Minagawa of Fukuoka, also in southern Japan, who was born in January 1893, Health Ministry official Ken Hongo said.

Hongo could not immediately say who is now the nation's oldest man.

The world's oldest living man is Emiliano Mercado Del Toro, 114, of Isabela, Puerto Rico, according to Guinness World Records.

Japan has one of the world's longest average life spans. In 2003, Japanese women set a new record for life expectancy, at 85.3 years, while men live an average of 78.3 years.
