Japanese mobile carrier market trends and competition

Overview

A survey by the MMD Research Institute highlighted a discrepancy in the Japanese mobile market between market share and customer satisfaction. While NTT Docomo holds the largest market share at 26.4%, it ranked lowest in overall satisfaction and recorded the lowest Net Promoter Score (NPS). Conversely, online-only plans and sub-brands such as KDDI’s povo, SoftBank’s LINEMO, and Rakuten Mobile achieved higher satisfaction rankings.

Following these market insights, major carriers have implemented aggressive pricing strategies to attract customers. Docomo has updated its ‘5G WELCOME割’ program to offer significant discounts on flagship devices like the Galaxy S26 and Google Pixel 11 through Mobile Number Portability (MNP) transfers. Similarly, KDDI’s au brand has increased discounts for the iPhone Air, offering potential reductions to as low as 47 yen when combined with specific upgrade programs and residual value systems.
