Quick answer
KDDI reduced customer churn to 1.17% and increased ARPU to 4,400 yen by abandoning smartphone subsidies and adopting an LTV-focused strategy.
Japanese telecom operator KDDI has delivered outstanding results in Q1 2027, with customer churn dropping to 1.17% and average revenue per user (ARPU) rising by 160 yen to reach 4,400 yen. These achievements stem from the company’s strategic abandonment of aggressive smartphone subsidies, which had previously been the primary tool for customer acquisition.
Under the leadership of President Hiroyuki Matsuda, KDDI pivoted toward a long-term customer value (LTV) strategy, shifting its business model from a race for new subscribers to a focus on retaining existing ones. A key element of this strategy involved leveraging the company’s three brands: premium au, budget UQ mobile, and flexible povo. Customers gained the ability to switch between plans within the ecosystem without losing connectivity with the operator.
By eliminating device subsidies, KDDI reduced marketing costs and reallocated resources toward improving service quality. The results validate the approach’s effectiveness: despite the absence of aggressive promotions, the company not only maintained its customer base but also enhanced profitability. This case study may serve as a benchmark for other telecom players seeking to escape price wars.
