The Japanese Self-defense Force (SDF) on Sunday began maneuvers in Narashino, Chiba province involving 20 airplanes and 33 armored vehicles. The exercise enacts a scenario in which a Japanese island is being occupied by an enemy and the airborne force tries to re-seize the island with the support of land and naval forces. Japanese Defense Minister Itsunori Onodera said Japanese security has worsened as neighboring countries are modernizing their armies and North Korea conducted two controversial satellite launches. According to Onodera, the SDF must protect national territory and ensure the safety of the Japanese people.
