In December 2022, the Japanese government revised for the first time in five years its National Security Strategy, National Defense Strategy, and Defense Force Development Plan, the three documents that define the basics of its security policy.

According to these documents, the defense expenditures are expected to total 43 trillion yen (about 310 billion US dollars) over the next five years, approximately 55% more than the 27.5 trillion yen spent over the previous five years (assuming 2% annual inflation, the real increase over the five years will approximately be 45%). With this increase, the goal is to raise the defense spending to 2% of GDP by 2027 (currently just over 1%).
