The announcement was made after Taiwan and other neighboring countries declared a no-fly zone in China on Sunday morning that would affect about 33 flights north of Taiwan.
China did not comment on the no-fly zone, but South Korea, which was also briefed on the plans, claimed the decision was made due to an object falling from a satellite launch vehicle.
Japan said on Thursday it had asked China for clarification on the no-fly zone.
China’s maritime security administration also said the restrictions would affect an area in the East China Sea between 9am and 3pm on Sunday.
The Ministry of Transport said the full-day closure of the airspace would “affect 18 international routes and 160 flights per day”.
