The Japan-based manufacturer has been WTCC's official tyre supplier since 2006.
The new deal extends their appointment to complete a full decade of Advan tyres in the championship.
"Since they began to supply the control tyre, they have always been extremely supporting to the championship," said WTCC general manager Marcello Lotti.
"Firstly as a competent and reliable technical partner, but also for their significant effort in promoting the championship worldwide, which helped us to establish events in crucial countries such as Japan, China and USA.
"To have them on our side for three more years is an invaluable benefit."
