The Malayan Tiger now joins other critically-endangered animals such as the Namdapha flying squirrel and the Asiatic cheetah.
The remaining tiger population is estimated to be only 5,000-7,000 with three of the traditional eight subspecies - the Javan, Bali and Caspian tigers - becoming extinct in the mid to late 20th century.
Kawanishi called on Malaysians to voice their concerns and show their support for their wild tigers.
