Installation Guide

CFAS Kyushu

CFAS is located on Kyushu island, about 45 miles (1.5 hour drive) from the prefecture's capital of Nagasaki and 78 miles (2 hour drive) from Fukuoka, largest city on the island. Sasebo is about 600 miles by air from Tokyo. The installation is composed of 12 separate areas on 1,285 acres bordering or near Sasebo Harbor. CFAS includes a main base area, three off-base housing areas, three fuel facilities, two ordnance facilities and a Landing Craft Air Cushion laydown site. For over 120 years two great navies, first the former Imperial Navy and now the U.S. Navy, have called Sasebo home. The city and nearby area are generally rural in comparison to other fleet concentration areas and features stunning natural beauty, including nearby 99 Islands National Park.

CFAS is the home of the Navy's only forward-deployed Amphibious Ready Group, anchored by USS America (LHA 6). Supporting America, our eight other forward-deployed ships and all U.S. Seventh Fleet ships is the mission of this installation. The base is strategically important in carrying out our defense treaty with Japan in ensuring peace and stability throughout the region. Proud of how we perform, CFAS is Commander Naval Region Japan's installation of the year in 2005, 2007 and 2009.
