Here is an interesting fact about the Northern Marianna Islands. The B-29 bombers that dropped the atom bomb on Hiroshima and Nagasaki started their mission from Tinian island, one of the main islands here. The islands are now a part of the United States.
Tourism is the mainstay of these islands which receive a large number of tourists from Japan and neighboring South East Asian countries. The three main islands here are Saipan, Tinian, and Rota (the capital is Saipan, and most tourists arrive here).
The islands are rich in biodiversity and have lovely beaches with white sand and turquoise blue water (some of the best diving spots in the world are located here as well). There are also a number of historical spots connected with World War 2 here.
