In recent years, the Indo-Pacific regional has become a focal point of tension, with GSDF officials saying the security environment surrounding Japan is the worst it's been since the end of World War II. "This Ground Self-Defense Force exercise is truly focused on improving operational effectiveness, deterrence and response capabilities," said Col. Noriko Yokota, GSDF spokesperson. "Each unit is conducting the exercise with an eye to what is necessary to achieve this goal. They are preparing themselves so that they can respond with confidence when they are forced to take further action."
