Visitor arrivals to the Northern Marianas were down six percent in April compared with the same month a year ago.
The Marianas Visitors Authority says just over 26,000 people visited the islands of Saipan, Tinian and Rota - down 1,600 on the previous year.
However, there was a big lift in visitors from South Korea - the fifth straight month of double digit growth in that market.
But arrivals from Japan, the other key market for the CNMI, were down by 26 percent in April.
