KDDI Targets AI Infrastructure and 6G Readiness in New 3-Year Plan

Why It Matters

By coupling massive AI‑centric infrastructure spending with early 6G development, KDDI aims to secure a competitive edge in Japan’s telecom market and open new high‑value services for enterprise and consumers. The initiative signals a shift toward data‑intensive, low‑latency offerings that could reshape revenue streams across the industry.

Key Takeaways

• KDDI will invest ¥1.2 trillion ($8.8 bn) in a Digital Belt.
• AI-driven network automation aims to cut optimisation time over 95%.
• Targeted 5% CAGR in operating profit through AI and 6G initiatives.
• Plans 100,000 6G base stations as nationwide sensing hubs.
• Joint 6G research with NTT, Fujitsu, NEC, Rakuten backed by government.

Pulse Analysis

KDDI's Power‑to‑Connect 2028 plan marks a decisive pivot toward AI‑powered infrastructure, reflecting a broader industry trend where telcos are becoming cloud and compute providers as much as connectivity carriers. The ¥1.2 trillion (≈$8.8 billion) Digital Belt will weave together low‑latency fiber, AI data‑centers, subsea cable landing points and satellite gateways, creating a backbone capable of supporting emerging services such as autonomous vehicles, immersive AR/VR, and real‑time analytics. By integrating AI at the core of network operations, KDDI expects to streamline maintenance, reduce energy consumption, and unlock new revenue from AI‑enhanced offerings.

The plan’s AI automation component already shows measurable gains. A field trial with Ericsson demonstrated uplink interference optimisation that boosted 4G/5G performance even as traffic rose 10%, while a multi‑AI base‑station optimizer cut manual tuning time by more than 95% and improved slow‑connection hotspots by 25%. These efficiencies not only lower operating costs but also free capacity for higher‑value services, positioning KDDI to meet the data surge anticipated from 6G‑enabled applications. The company’s focus on talent development and nationwide sensor deployment further underscores its ambition to become a data‑centric platform rather than a traditional voice‑and‑data carrier.

Looking ahead, KDDI’s 6G roadmap hinges on deploying roughly 100,000 base stations as sensing hubs, feeding AI‑driven network management with real‑time environmental data. Collaboration with industry peers—NTT, Fujitsu, NEC, Rakuten—and support from Japan’s Ministry of Internal Affairs and Communications accelerate standardisation and reduce time‑to‑market for 6G technologies. Coupled with the launch of au Starlink Direct, KDDI is also expanding low‑Earth‑orbit satellite connectivity, broadening coverage in remote areas. Together, these moves aim to capture new enterprise contracts, enhance consumer experiences, and solidify KDDI’s role in Japan’s next generation of digital infrastructure.
