Japan's Go To Travel domestic tourism subsidy program may resume in February after being suspended since late last year amid a resurgence in COVID-19 cases, with the campaign to include compulsory virus countermeasures, government sources said Thursday.

While the number of new and serious COVID-19 cases in the country has sharply declined recently along with the progress of the vaccination program, the government believes it still needs to evaluate whether oral drugs for preventing serious symptoms will be available by the end of the year, the sources said.

The government is planning to require people taking advantage of the Go To Travel program to show proof of vaccination or a negative virus test result when they check into accommodation and on other occasions, according to the sources.
