The number of people arriving at Narita Airport east of Tokyo from South Korea during Japan's mid-August holiday period was down sharply from a year before amid worsening of the two countries' ties.
According to the Narita Airport branch of Tokyo Regional Immigration Bureau, more than 1.05 million people used the airport for international flights during the "bon" holidays from August 9 through 18. The figure is up 4.6 percent from the same period last year.
The most popular destinations were Hawaii and other places in the United States, at 110,000 departures.
More than 58,000 people left for South Korea. The figure is up 4.3 percent from last year.
But arrivals from the country were down 35 percent, to 12,000.
Koji Shiotani, a senior official of the bureau's Narita Airport branch, attributed the sharp decline to the impact of Japan-South Korea relations.
In South Korea, there are calls for people to refrain from traveling to Japan. Several South Korean airlines have suspended or cut the number of flights to the country.
