Guam is stepping up its effort to attract more Japanese tourists after they fell from the top spot of visitors who vacation on the Pacific island.

According to the Guam Visitors Bureau, arrivals from Japan fell 16.8 percent in 2017 to 620,547, giving way to South Korea, which gained 25.6 percent to 684,443, a record high for the country.

The U.S. territory in the Pacific Ocean, whose main attractions are its beaches and tropical weather, received a total of 1.54 million tourists last year, the highest ever.
