KDDI Subsidiaries Falsified Advertising Transactions Totaling ¥246.1 Billion, 99.7% Deemed Phantom

KDDI said ¥246.1 billion of sales should be corrected and ¥32.9 billion flowed externally in a fictitious-ad scheme.

The scheme involved Biglobe and its subsidiary G-Plan and spanned transactions from April 2017 to December 2025.

Executives resigned and two employees were dismissed, and KDDI will pursue civil claims, recovery, and possible criminal charges.
