He succeeds Alexander Imich, of New York, who died in April at the age of 111 years, 164 days.
The world's oldest living person is also Japanese: Misao Okawa, a 116-year-old woman from Osaka.
Father-of-five Mr Momoi used to work as a high school principal near Tokyo. He now lives in a nursing home.
