Tokyo Gov. Yuriko Koike said Wednesday the nation's capital will prepare an ¥800 billion emergency spending package in response to the COVID-19 outbreak.

The relief package will be "far bigger than" those compiled after both the 2008 Lehman shock during the global financial crisis and the March 2011 earthquake and tsunami that ravaged a large portion of the country, the governor said during a news conference at the Tokyo Metropolitan Government office.

The Tokyo government plans to submit a ¥357 billion supplementary budget bill to an emergency assembly session from Friday and to draft additional measures later.
