Support Activities
Firm Infrastructure
KDDI Corporation's firm infrastructure must coordinate mobile, fixed-line, and data center assets at national scale, so board oversight and regulatory compliance are core value-chain tasks. In FY2025, KDDI Corporation reported revenue of about ¥5.9 trillion and capital spending of about ¥0.6 trillion, showing how capital-heavy this layer is. Strong network planning helps KDDI Corporation match long-lived telecom assets with demand, service quality, and Japan's strict rules.
Human Resource Management
KDDI Corporation depends on network engineers, software staff, sales teams, and customer support to keep 24/7 telecom and cloud service running. In FY2025, that skill mix matters because fast fault fixes and stable service quality affect churn, uptime, and brand trust. Training and retention are key, since one weak link can slow response across the whole network.
Technology Development
KDDI Corporation's technology development keeps au, UQ mobile, povo, and enterprise services fast and stable through 5G, core network, cloud, AI, IoT, and data center upgrades. In FY2025, KDDI reported about ¥5.7 trillion in operating revenue, showing the scale behind these platform investments. That spend supports lower latency, better uptime, and stronger digital services for both consumers and corporate clients.
Procurement
KDDI Corporation buys network gear, software, device inventory, fiber, and radio-access equipment from a broad supplier base, so procurement directly affects capex and rollout speed. In FY2025, tight supplier control mattered as KDDI kept nationwide network quality high while upgrading 5G and fixed-line assets. That makes procurement a core driver of cost discipline and service reliability.
KDDI's Support Engine Behind ¥5.9T Revenue and Network Uptime
KDDI Corporation's support activities are built to keep a nationwide telecom and cloud network stable, compliant, and fast to fix. FY2025 revenue was about ¥5.9 trillion, and capital spending was about ¥0.6 trillion, so these functions sit behind a heavy asset base. Procurement, HR, and network engineering all shape uptime and rollout speed.

Primary Activities
Inbound Logistics
In FY2025, KDDI Corporation's inbound logistics focused on securing spectrum-related licenses, network gear, handsets, software, and data-center inputs from domestic and global vendors. This matters because KDDI Corporation reported about ¥5.9 trillion in operating revenue in FY2025, and supply timing directly affects 5G rollout, fixed-line builds, and cloud capacity.
Short lead times on radios, optical gear, and servers help KDDI Corporation control deployment schedules and service quality.
Operations
KDDI Corporation's Operations runs mobile, fixed-line, internet, cloud, and data center networks, plus billing and provisioning systems, so uptime and low latency drive service quality. In FY2025, KDDI Corporation posted about ¥5.9 trillion in revenue and roughly ¥1.0 trillion in operating profit, which shows how scale and network efficiency support margin power. Strong operations also cut unit costs across consumer and enterprise services, especially where cloud and data center demand keeps rising.
Outbound Logistics
KDDI Corporation pushes outbound logistics through SIM and eSIM activation, app-based onboarding, and enterprise provisioning, so service delivery starts fast and with little physical handling. It backs this with retail stores, online channels, and corporate account teams for both mass-market and business customers.
KDDI's scale supports this model: in FY2025, it generated about ¥5.9 trillion in revenue, which helps fund broad channel coverage and digital fulfillment.
Marketing and Sales
KDDI Corporation uses au, UQ mobile, and povo to split premium, value, and online-first users, with bundles, loyalty perks, and digital pricing plans driving conversion. This structure supports cross-sell into fixed-line and corporate services, while KDDI reported more than 80 million mobile subscriptions in FY2025, giving its sales engine scale.
The brand mix also helps KDDI Corporation defend share in a mature market, because it can match price to usage without losing customers to rivals. In value-chain terms, marketing and sales link directly to higher lifetime value, since one account can move across mobile, home, and business offerings.
Service
In FY2025, KDDI Corporation reported about JPY 5.9 trillion in revenue and over JPY 1.0 trillion in operating income, showing how service quality supports scale and profit. Its service layer covers customer support, device help, network maintenance, and managed enterprise services, which keeps the au and corporate base sticky. In a 24/7 market, fast repairs and reliable support cut churn, lift upsell, and protect trust.
KDDI's FY2025 Network Engine: ¥5.9T Revenue, 80M+ Subs
