Tourism authorities in Japan say the number of visitors from South Korea in September was less than half the figure from the same month last year, reflecting strained bilateral relations.
The Japan National Tourism Organization estimates that 201,200 South Koreans visited Japan last month. That's down 58.1 percent from a year ago.
The decline started in July, dropping more than 7 percent, and the pace accelerated in August, when the number plunged by 48 percent.
The overall picture of Japan's tourism industry appears to be good, as the number of tourists from abroad is estimated to have risen by 5.2 percent, to more than 2.27 million.
The decline in the number of tourists from South Korea contrasts with the increase of tourists from other major countries.
