Japan has ended its peacekeeping mission in troubled South Sudan after five years.
Japan would not renew the mission after the current rotation returns in May.
The 350-person team has focused on road construction.
The team, which arrived in South Sudan in November, was Japan’s first to have an expanded mandate to use force if necessary to protect civilians and U.N. staff.
The Japanese military’s use of force is limited by its post-World War II constitution.
The South Sudan mission was the longest for Japanese troops, who also have served in Golan Heights, Cambodia and other areas for post-cease-fire assistance limited to noncombat roles.
