The sub-central government procurement in Japan, excluding social security funds, has been progressively growing since previous years. In 2023, the procurement value was at a certain baseline from which projections indicate a steady increase, reaching $320.4 billion by 2027 and $323.7 billion by 2028 in terms of purchasing power parity. On average, the compound annual growth rate (CAGR) over the past five years is modest, highlighting a stable yet incremental expansion.

The year-on-year growth reveals a consistent upward trend, reflecting the government's ongoing investment and spending increases at the sub-central level. This pattern suggests a continued commitment to infrastructure and local government functions.

Future trends to watch include:

Potential policy shifts influencing budget allocations at the sub-central level.
Impacts of demographic changes on procurement demands and practices.
Evolving priorities in public procurement driven by technological advancements and environmental considerations.
