The defense buildup approved by the government on Friday could see Japan's ranking in terms of defense expenditures rise to third in the world based on planned spending of about 11 trillion yen in fiscal 2027.
Japan sits ninth in the Stockholm International Peace Research Institute's 2021 defense spending ranking.
Japan's fiscal 2027 defense spending -- the defense budget plus defense-related expenditures --is expected to be almost equivalent to 2% of the nation's current gross domestic product.
The defense budget, which stood at 5.4 trillion yen in fiscal 2022, is expected to be boosted to about 8.9 trillion yen in fiscal 2027.
The government aims to reach 11 trillion yen by including the Japan Coast Guard budget and expenditures in such fields as defense-related research and development; infrastructure development; cyber countermeasures; and international cooperation.
The North Atlantic Treaty Organization encourages its members to spend at least 2% of GDP on defense.
