In September 2026, NTT East and NTT West announced changes to telephone service billing rules, including the unification of billing periods for landline services. Concurrently, Japan’s Ministry of Internal Affairs and Communications received a report proposing new consumer protection measures to prevent unexpected charges and simplify contract cancellations, with a specific focus on protecting elderly users.

Following these developments, NTT Docomo announced that starting in February 2027, it will introduce a “late payment collection administrative fee” of 385 yen for customers who fail to meet payment deadlines and require formal notification regarding service suspension or contract termination.
