Japan and South Korea's leading telecom operators are poised for growth driven by mandated 5G Standalone upgrades, aggressive expansion into AI data centers and cloud infrastructure, and stable core connectivity services, despite intense competition and significant capital expenditure requirements.
South Korea's government has mandated 5G Standalone (SA) upgrades for national operators by 2026, offering incentives like LTE fee reductions to accelerate the transition. This regulatory push is critical for enabling advanced AI applications, network slicing, and preparing for 6G, driving significant network modernization across the industry.
Telecom operators are aggressively expanding into AI data centers and cloud infrastructure, moving beyond traditional connectivity. KT plans an 18 trillion won investment, including 6 trillion won for AI data centers targeting 1GW capacity, while SK Telecom launched SK Horizon with $2.2 billion for AI data center expansion. KDDI is also investing JPY 1 trillion in AI integration, cloud, and data centers.
The core telecom services, including wireless, fixed-line broadband, and enterprise connectivity, continue to provide a stable economic foundation and growth. The Japan telecom market is projected to grow at a CAGR of 4.36% from 2026-2034, driven by nationwide 5G rollout, enterprise digitalization, and sustained demand for data-intensive applications and IoT services.
Intense competition and pricing pressure persist in both markets. The Japanese telecom market remains "uncomfortably competitive," with revenue growth shifting to lower-margin businesses and mobile services revenue remaining broadly flat. Rakuten Mobile's aggressive pricing strategies and subscriber growth, surpassing 11 million as of September 2026, continue to challenge incumbents.
Significant capital expenditure is required for 5G SA upgrades and the build-out of AI data centers and cloud infrastructure. Operators like KT are committing trillions of won to these investments, and Rakuten Mobile's high capital expenditure has widened its free cash flow deficit, posing a risk to profitability and financial flexibility.
The regulatory environment is evolving with increased scrutiny on competition and digital platforms. Japan's Fair Trade Commission will enforce the new Smartphone Act by the end of 2025, similar to the EU's Digital Markets Act. In South Korea, regulators are actively addressing competitive practices, including a legal battle over alleged coordination of subscriber portability among carriers.
