• North Korea has increased criticism of Japan's military buildup.
• Pyongyang targets Japan's acquisition of counter-strike capabilities and rising defense spending.
• North Korea warns of 'additional military options' in response to Japan's transformation into a military power.
• Recent missile launches have been unusually unpublicized.

North Korea's criticism may indicate an attempt to frame Northeast Asia as a contest between rival camps, which could strengthen its ties with China and Russia. This strategy suggests a broader effort to justify its nuclear arsenal and military expansion, potentially destabilizing regional security.
