Japanese Prime Minister Yoshihide Suga partially halted the Go To Travel domestic tourism campaign yesterday as Covid-19 cases continued to soar nationwide.
The abrupt U-turn just days after saying the scheme would continue as planned came as hospitals have begun to feel the strain from the explosive growth in infections.
Japan had a fourth straight record-busting day yesterday with at least 2,560 cases, driven by new peaks in cities like Tokyo and Osaka, but clusters have also arisen in rural regions that are far less equipped to deal with the crisis.
"We will temporarily stop taking new reservations under the Go To Travel programme for destinations where infections are on the rise," Mr Suga said.
But Tourism Minister Kazuyoshi Akaba said later that the finer details - such as where the affected areas are and when the suspension will start - have yet to be worked out.
The Go To Travel scheme gives subsidies to travellers with the aim of reviving the hospitality industry. Under the scheme, up to 20,000 yen (S$260) of discounts are available for an overnight stay.
Dr Toshio Nakagawa, who heads the Japan Medical Association, and Dr Haruo Ozaki, who leads the Tokyo Medical Association, said the campaign had surely acted as a vehicle to spread the virus as it drives the movement of millions across the country.
The resurgence in cases in the past week did nothing to stop millions from going on holiday as the country marked the start of a three-day-long weekend yesterday.
Flights and shinkansen bullet trains were full, while traffic jams stretching over as much as 26km were recorded on major expressways.
Tourists cited the fact that their vacations had been planned months in advance and that it would be a waste to incur cancellation fees as reasons for going ahead with their trips. Others said they would have thought twice about travelling had the government made the first step to suspend the Go To Travel scheme.
A woman told TBS News before she boarded the bullet train bound for Morioka in Iwate prefecture in north-east Japan: "The fact that the campaign is still ongoing is tacit permission that travel is OK.
"Why can't the government be more decisive?"
Yesterday's tally was driven by new peaks in areas like Tokyo, where 539 cases marked the third straight day the city has logged more than 500 infections.
It was also the first day the Greater Tokyo region, the world's most populated area, crossed a cumulative 1,000 cases.
Chiba, east of Tokyo, set a new high of 109 cases, while Saitama to the north had a new peak of 173 infections. Kanagawa to the south recorded 193 new cases.
Osaka in western Japan had a third consecutive record-breaking day with 415 cases. Hyogo prefecture, where the city of Kobe is situated, registered a new peak of 153.
Other areas also saw high tallies. Aichi prefecture, where Nagoya is situated, had 211 cases, while Hokkaido added 234 infections, mostly in Sapporo.
The decision to suspend the Go To Travel scheme in hard-hit areas came after Dr Shigeru Omi, who heads a government panel of medical experts, said on Friday: "Just relying on the behaviour of individuals may not continue to work, given the increasing number of clusters in unpredictable areas, and the rising numbers of untraceable infections."
