Japanese Prime Minister Shinzo Abe on Monday proposed a stimulus package worth some $1 trillion (108 trillion yen), which is 20 percent of the country's GDP.
"We hope to declare a state of emergency as early as tomorrow after listening to the opinions of the advisory panel," Abe told reporters.
The measures will affect Tokyo and its surroundings and six other prefectures. However, "unlike in the foreign countries, the cities will not be closed", Abe said.
