Toshihiro Nagahama, chief economist at the Dai-ichi Life Research Institute, takes a critical stance toward Abe's explanation about the amount of fiscal spending.
Since days before the Cabinet approval, Abe had promised the country's "boldest-ever" stimulus, even more than the 56.8 trillion yen package it introduced in the aftermath of the 2008 global financial crisis.
Of the total amount, 1.68 trillion yen has been earmarked to stimulate consumption and help tourism-related industries recover after the spread of the virus is finally contained.
"Even if people received 300,000 yen and lived in the most frugal ways, (the relief) won't survive less than three months," Kobayashi said.
"The next package will likely consist mainly of livelihood support steps, again."
