Japan’s 5G millimetre-wave technology market is expected to reach $1.27288 billion by 2035, up from $339.59 million in 2025. The CAGR over the period is projected to be 14.1%. Advances in digitalisation, industrial DX and edge adoption will support growth.
Japan’s 5G millimetre-wave technology market is expected to expand from $339.59 million in 2025 to $1.27288 billion by 2035, with a projected CAGR of 14.1% from 2026 to 2035. Market expansion is closely linked to the promotion of DX, the advancement of industrial networks, the spread of edge computing and continued investment in communications infrastructure.
The adoption of millimetre-wave technology is intended to meet rising demand for high-density, high-capacity data communications, with applications expected in environments with large concentrations of devices, including stations, commercial facilities, stadiums and factories. At the same time, coverage distance and the impact of obstructions remain challenges, making optimisation through combination with Sub-6 important.
The promotion of smart factories and DX in the manufacturing sector is supporting the industrial use of 5G millimetre-wave technology. High-capacity data processing is required for high-definition video transmission, monitoring of industrial robots, real-time collection of equipment data and remote work support using AR. The use of private 5G makes it easier to build systems tailored to individual company requirements.
In terms of technological competition, advances in base-station equipment, antennas and RF semiconductors are essential, and the development of high-value-added products that capitalise on Japan’s strengths in electronic components and materials will be important. Efforts to reduce the total cost of ownership, including deployment and operating costs, and the provision of integrated AI and edge solutions will be key to market competitiveness.
