The Tokyo Metropolitan Government confirmed 107 new cases of COVID-19 on Sunday, down from 181 a day earlier and bringing the overall total in the capital to 3,082.
The new figure came as 26 infections were found in Hokkaido and 17 in Kanagawa Prefecture. The total number of cases of the deadly virus in Japan topped 10,000 the previous day.
Tokyo, which has more infections than any prefecture, reported a single-day high of 201 on Friday.
The capital also said three COVID-19 infected individuals died on Sunday, bringing the total number of deaths to 71 in Tokyo.
On Thursday, Prime Minister Shinzo Abe expanded the state of emergency to nationwide from Tokyo and six other prefectures.
The widening of the state of emergency is aimed at preventing people from traveling during the Golden Week holidays, which start later this month and run into early May.
