Japan’s Olympics minister said the country is committed to hosting the summer games as planned from July even as the coronavirus outbreak spread to new parts of the country.

“Cancellation or delay of the Games would be unacceptable for the athletes,” Seiko Hashimoto said in parliament on Thursday. “An environment where athletes can feel at ease and focus should be firmly prepared.”

The minister had caused controversy earlier this week by saying the contract for the games “could be interpreted as allowing a postponement” within calendar 2020.

Japan’s western prefecture of Shiga reported its first coronavirus infection on Thursday, a day after the announcement of a first case in the southern prefecture of Miyazaki.

Confirmed coronavirus infections rose to 1,036 nationwide as of Thursday morning, 36 more than the previous day, according to national broadcaster NHK. That was the biggest one-day increase to date, with new cases in locations ranging from Kumamoto prefecture in the southwest to Hokkaido in the north.

Twelve people have died from the disease, according to the health ministry.

The rapid spread of the outbreak has raised questions about whether Tokyo can host the Olympics as scheduled from July 24, with the effects being felt by other sporting events.

On Wednesday, the Japanese Rugby Football Union announced that next month’s Asia Sevens Invitational, which doubles as a test event for rugby sevens at the Tokyo Olympics, has been canceled due to concerns over the coronavirus outbreak.

The Tokyo marathon was held this month without the participation of non-elite runners, and with fewer volunteers and spectators.

Hashimoto told the upper house on Thursday that organizers and the International Olympic Committee (IOC) would continue to work together closely. She reiterated the final decision on holding the games as planned rests with the IOC.

On Wednesday, IOC President Thomas Bach said the words ‘cancellation’ or ‘postponement’ were not mentioned during a two-day meeting focused on preparations for the Games.

Asked what made him so confident the Games would go ahead, Bach said the IOC and 2020 Games organizers were receiving expert information, including from the World Health Organization.
