The Japanese military has built its own air base in the African country of Djibouti.  The official reason is to help fight pirates.

The Japanese had been sharing a base with the United States, but built its own 12 hectare (29.6 acre) airfield for its surveillance aircraft.

The French have long time military ties to the country of Djibouti, but since the surge in piracy, Djibouti is making money off of allowing several countries (including the U.S.) to base military units there.
