TOKYO - Governor Yuriko Koike won a second term in the Tokyo gubernatorial election on Sunday, local media reported.

Koike also said she could not feel completely happy as Tokyo was facing a possible second wave of the pandemic

"I am very happy, and simultaneously feel the heaviness of the responsibility," the 67-year-old politician said in a televised address as exit polls suggested she was likely to score a landslide victory.

Koike vowed to seriously deal with a second wave of COVID-19 and coordinate with the International Olympic Committee over the postponed Olympics and Paralympics in 2021.

"This is a critical time to be prepared for the second wave of coronavirus. We would like to respond firmly," she said.
