Dentsu Japan ‘irregularities’ involved 100 clients

The transparency scandal to emerge from Japan yesterday involves 100 of Dentsu’s clients and 160 incidences of irregularities in digital media pricing over a three year period, according to sources close to the matter.

An audit was initially carried out to investigate digital media over-billing for Dentsu’s flagship client Toyota, and was later applied across the Japanese agency giant’s huge client portfolio to check for further misdealing, Mumbrella Asia reports.

Toyota’s headquarters in Japan confirmed with Mumbrella that the car maker had been notified by Dentsu of the “irregularities”, but declined to go into any more detail.
