Japanese Prime Minister Sanae Takaichi is reportedly becoming hesitant to commit to a specific defense spending target as a percentage of gross domestic product, particularly the 3.5% level that the U.S. is seeking. This caution stems from the perceived difficulty Japan would face in achieving such a target within a five-year timeframe.
Defense officials in Japan have signaled to their U.S. counterparts a willingness to significantly increase defense outlays. One potential scenario being considered is for Japan to match South Korea's commitment to raise defense spending to 3.5% of GDP over a 10-year period. Another possibility is a lower target of around 3% of GDP.
News of Japan's deliberations has caused concern in financial markets, which are already contending with rising borrowing costs due to climbing government bond yields. The yield on Japan's 10-year government bond surpassed 3% on Tuesday, reaching its highest point since 1996. The Bank of Japan is widely expected to raise its policy rate by 0.25 percentage points soon, which could further increase government borrowing costs.
A persistently weak yen adds another layer of pressure, eroding Japan's purchasing power for overseas weapons and potentially undermining defense expansion plans. Analysts note that fiscal concerns make it difficult for investors to view the news positively, with questions also raised about Japan's capacity to meaningfully expand its defense capabilities.
