The military coup in Myanmar in 2021 has triggered a profound humanitarian crisis, characterized by extensive human rights abuses, rising violence, and the curtailment of democratic freedoms. This section explores the decline in human security in Myanmar post-coup, highlighting the surge in displacement, economic struggles, and human rights violations. The study indicates a notable increase in refugees, fatalities, unemployment, and poverty, with more than 3.2 million people displaced and a third of the population in need of humanitarian assistance. The weakening of democratic institutions and the enforcement of martial law have worsened the situation, resulting in unchecked military misconduct and a lack of accountability. The international community, including Japan, has been under growing pressure to address the crisis. Japan’s strategy, expressed through diplomatic communications, has stressed the urgency of halting violence, freeing detainees, and reinstating democratic processes while committing to humanitarian aid. However, the provision of international assistance has been obstructed by the military’s restrictive measures and ongoing conflicts, rendering many areas inaccessible to aid workers. As the crisis deepens, with millions experiencing food insecurity, displacement, and limited access to essential services, the international community faces the complex challenge of delivering crucial humanitarian aid while maintaining pressure on the military regime to uphold human rights and restore democratic governance. The ongoing human rights violations and escalating humanitarian crisis highlight the vital need for sustained international involvement and support through well-coordinated and unhindered humanitarian aid for Myanmar’s vulnerable populations.
