Anticipating China's growing naval prowess, Japan's Self-Defense Forces (SDF) are reported to organize a comprehensive training exercise in June. The rigorous preparation comes in response to China's continuous expansion of its military capabilities, particularly its naval forces—exemplified in its recently revealed aircraft carriers. The SDF's responsiveness aims to reassure regional safety and maintain Japan's rights and interests.

Japan views China's military expansion as a potential threat to regional stability. National security, under the principles of self-defense and peace, is a high priority, and preparing for various scenarios to ensure readiness is crucial. Japan's public generally supports the defense forces' efforts in maintaining security, but with the understanding that Japan adheres to its pacifist constitution.

Similar to the US or EU, Japan sees the importance of maintaining a military readiness to volatile geopolitical situations. However, unlike the US's global military presence or EU's multinational defense collaboration, Japan's military operations are severely limited by its constitution, focusing mainly on self-defense and peacekeeping missions.
