Chubu Centrair International Airport in central Japan saw more passengers than usual on Thursday, the first day of a four-day weekend, while staff implemented anti-coronavirus measures.
Long lines formed at check-in counters.
Transparent dividers were installed on the counters. Staffers served customers while wearing face masks and face shields.
All passengers on domestic flights had their body temperatures checked before boarding. Airlines say people with high temperatures could be refused boarding.
The number of domestic flights had been reduced to 36 as of July 1, due to the impact of the coronavirus pandemic. But 63 were scheduled on Thursday.
A woman heading to Ehime Prefecture with her family said she was relieved to see thorough anti-virus measures in place at the airport.
A man taking a family trip to Kumamoto Prefecture said he is planning to apply for incentives under the government's "Go To Travel" tourism-promotion campaign. He added that he and his family will try to avoid crowded places as more tourists than usual are expected during the long weekend.
