Nonstop flight route between Okinawa, Japan and Washington, D.C. / Virginia, United States:

About this route:

A direct, nonstop flight between Naha Airport (OKA), Okinawa, Japan and Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States would travel a Great Circle distance of 7,653 miles (or 12,316 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Naha Airport and Washington Dulles International Airport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Naha Airport and Washington Dulles International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Naha Airport (OKA):

• Because of Naha Airport's relatively low elevation of 11 feet, planes can take off or land at Naha Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• The airport is served by the Okinawa Monorail which carries passengers from Naha-kūkō Station to the center of Naha, and to the terminal at Shuri Station near Shuri Castle.
• The furthest airport from Naha Airport (OKA) is Paulo Abdala Airport (FBE), which is nearly antipodal to Naha Airport (meaning Naha Airport is almost on the exact opposite side of the Earth from Paulo Abdala Airport), and is located 12,392 miles (19,943 kilometers) away in Francisco Beltrao, Paraná, Brazil.
• Naha Airport (OKA) currently has only 1 runway.
• In addition to being known as "Naha Airport", other names for OKA include "那覇空港" and "Naha Kūkō".
• The closest airport to Naha Airport (OKA) is Kadena Air Base 嘉手納飛行場 Kadena Hikōjō (DNA), which is located only 13 miles (21 kilometers) NE of OKA.
• The basic and detailed design engineering works in addition to the later construction management phase of the main passenger terminal were awarded in the 1990s in part to the Japan Branch of the American design-build engineering company, The Austin Company, which joined Japanese firms in a joint venture design consortium.

• By the 1980s, the original design, which had mobile lounges meet each plane, was no longer well-suited to Dulles' role as a hub airport.
• The C and D concourses, completed in 1983 and designed by Hellmuth, Obata and Kassabaum, were originally designed as a temporary base for United Airlines, which began hub operations at the airport in 1985.
• Under the development plan, future phases would see the addition of several new midfield concourses and a new south terminal.
• Washington Dulles International Airport (IAD) has 5 runways.
• Concourse A consists of a permanent ground level set of gates designed for small planes such as regional jets and several former B concourse gates.
• Because of Washington Dulles International Airport's relatively low elevation of 313 feet, planes can take off or land at Washington Dulles International Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
