Japan recorded 1,240 new coronavirus cases and six virus-related deaths on Tuesday, as the country grapples with a recent spike in infections.
Tuesday's figures raise the national total to 41,841 cases and 1,035 deaths.
Of Tuesday's new cases, abut a quarter came from the country's capital, Tokyo. This is the eighth straight day that Tokyo has recorded more than 200 new daily cases.
Two thirds of the city's Tuesday cases are untraceable, meaning authorities were unable to find out the source of infection, said the metropolitan government.
Other major cities like Osaka also saw high numbers of new cases, raising concerns among local politicians. The governor of Kanagawa prefecture, which neighbors Tokyo, said he expected the rise in Tokyo cases to also spread into his prefecture.
A spike in cases: For months, Japan seemed to have the virus largely under control. Throughout most of May and June, daily case numbers hovered around several dozen, ranging from around 20 to 60 a day.
But case numbers passed 100 on June 30, and have only continued rising since then, jumping by hundreds in a matter of weeks.
