The total internal R&D personnel in services in Japan is projected to see a gradual decline from 2024 to 2028, starting at 62.4 thousand full-time equivalents in 2024 and decreasing to 62.35 thousand by 2028. This represents a slight downward trend, with year-on-year variations remaining minimal, indicating relative stabilization in the workforce size.

Key future trends to watch for include:

The impact of emerging technologies on service-based R&D, potentially influencing personnel needs.
Japan's demographic changes could further pressure workforce availability.
Policy shifts aimed at increasing innovation and productivity in the service sector may alter these projections.
