In late July 2026, Japan’s cabinet approved the “Economic and Fiscal Management and Reform Basic Policy 2026,” known as the Kottai policy. The plan replaces fiscal consolidation language with a commitment to “responsible active fiscal policy” and outlines more than 370 trillion yen of public‑private investment over the next two decades in AI, semiconductors, defense and other sectors, alongside reforms to consumption‑tax timing, minimum‑wage targets, health‑insurance cost‑sharing and OTC‑drug coverage. Critics warned that the country’s debt would exceed 1,145 trillion yen, and markets reacted with a bond‑sell‑off, higher yields and yen depreciation.

A few days later, Japan’s Ministry of Defense submitted a request for the 2027 fiscal year that would allocate a record 8.9 trillion yen (potentially rising to about 10 trillion yen) to defense spending. The budget targets new combat capabilities, including large‑scale procurement of intercept drones, AI‑enhanced command systems, high‑power laser and microwave air‑defence technologies, and a secure cloud platform for classified data. This request fits within the broader 2023‑2027 defence plan of roughly 43 trillion yen, reflecting the Kottai policy’s emphasis on modernising the Self‑Defense Forces amid regional security concerns.
