People in Japan are expressing weariness about having to put up with an extension of the coronavirus state of emergency until the end of May, part of an effort by the government to suppress a resurgence of infections ahead of this summer's Tokyo Olympics.

At Tokyo's Haneda Airport, few travelers were seen on Saturday, following the government's decision announced the previous day to extend the emergency covering Tokyo and the greater Osaka area. The emergency was initially slated to end Tuesday.

"There is no end in sight," said Motohiro Nagata, 65, who was heading to Toyama Prefecture. "I can't plan ahead as the government changes the period (of the emergency) and details of the anti-virus measures so often."
