Tokyo To Update National Security Documents Amid Rising Tensions

The revamped cabinet of Japanese Prime Minister Sanae Takaichi is set to accelerate debates on strengthening the country’s defense capabilities, with the government planning to update its three key national security-related documents by year-end. The focus will be on the size of the defense budget and financial resources, as China and Russia step up their military activities around Japan. The government has already earmarked about 11 trillion yen in defense budget in fiscal 2025, achieving its goal of raising the proportion of defense spending to gross domestic product to 2 pct two years ahead of schedule. This development was reported by Jiji Press.
