Japan’s fixed communication services revenue is set to remain largely stable between 2025 and 2030 as steady expansion in fiber broadband offsets the continued decline of traditional voice services. The shift underscores a structural transition in the country’s telecom market, where operators are prioritizing high-speed connectivity and bundled offerings to defend revenue growth in an otherwise mature and highly saturated fixed-line sector, reveals GlobalData, a leading intelligence and productivity platform.
GlobalData’s Japan Fixed Services Forecast (Q4-2025) reveals that fixed communication services revenue in Japan is expected to grow from $26.4 billion in 2025 to $26.9 billion in 2030, maintaining a compound annual growth rate (CAGR) of just about 0.4%, driven by continued growth in fixed broadband services.
Fixed voice service revenue will drop at a CAGR of 1.8% over the forecast period as operators offer free voice telephony as a part of multi-play bundled plans. Fixed broadband service revenue, on the contrary, is expected to increase at a moderate CAGR of 1.3%, supported by steady growth in fiber-optic access lines.
Neha Mishra, Telecom Analyst at GlobalData, comments: “Fiber will remain the leading broadband technology, increasing its share of total fixed broadband subscriptions from 87.9% in 2025 to 88.8% in 2030. Growing demand for high-speed broadband connectivity, government’s focus on fiber-optic network expansion and the gradual phasing out of DSL services in the country will support the growth in fiber broadband subscriptions over the forecast period. Japan aims to achieve 99.9% residential fiber-optic coverage by the end of 2027.”
NTT led the fixed broadband services market in 2025 and is expected to maintain its leadership through 2030. NTT maintains its leadership in the fixed voice market through its strong presence in both circuit-switched and VoIP segments. In the fixed broadband segment, NTT attracts a wide customer base by offering diverse tariff plans, including fixed-rate options and tiered pricing based on data usage, catering to both entry-level and premium users.
Neha concludes: “Japan’s fixed services market will remain defined by fiber-led connectivity and bundled digital services. As broadband becomes the core revenue engine, operators will increasingly focus on network upgrades, premium speed tiers and value-added services to sustain growth. Competitive differentiation will depend on service quality, pricing flexibility and the ability to monetize high-capacity fiber networks.”
