Prime Minister Fumio Kishida has set a target of speeding up COVID-19 booster vaccinations to a million shots a day by the end of the month, as the government eyes extending the quasi-emergency measures in Tokyo and 12 other prefectures.

Kishida told parliament Monday that his government would step up operations at large-scale vaccination facilities as it tries to reach the target. Employers would also be encouraged to press ahead with workplace boosters, he said.

"By setting a clear goal, the government as a whole will work to deliver shots to those who hope to be vaccinated as soon as possible," Kishida said at a parliamentary session.
