The Tokyo Metropolitan Government confirmed 102 new cases of COVID-19 on Monday, a slight improvement from the 107 reported Sunday.
The new cases brought the overall total in the capital to 3,184. The highest single-day number for Tokyo so far was 201 last Friday, according to metropolitan government data.
Across Japan, the cumulative number of people found infected with the virus, excluding those aboard the Diamond Princess cruise ship, exceeded 11,000 on Monday with an additional 245 cases.
The number of deaths on Monday reached 20, the highest for a single day, bringing all COVID-19 deaths in Japan to 271.
Prime Minister Shinzo Abe last week expanded the state of emergency from Tokyo and six other prefectures to the entire nation.
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.
