The war in Iran is beginning to impact inbound travel to Japan, with the conflict resulting in canceled flights and closed airspace.
Following U.S. and Israeli strikes on Iran and the ensuing war, a number of flights have been canceled as airports and airspace in the region face closures. As a result, hotels in Japan have seen cancellations from those planning to visit from Europe via major airports in the Middle East.
Meanwhile, airfares are rising globally due to higher aviation fuel costs reflecting soaring crude oil prices, potentially impacting inbound travel to Japan.
