The Japanese prime minister, Shinzo Abe, announced the decision to join the centre during his visit to Estonia on 12 January.
According to a statement by the cyber defence centre, this will further strengthen the knowledge base and reach of the currently 20-nation-strong centre.
Merle Maigre, the director of the centre, said it welcomed Japan’s decision to join as a contributing participant, a type of membership available to non-NATO countries.
“Japan is one of NATO’s key partners beyond the Euro-Atlantic area and a globally recognised technology and cybersecurity power,” she said in a statement. “Joining the centre will be a concrete step forward signalling the commitment in cyber defence cooperation between like-minded nations.”
The NATO Cooperative Cyber Defence Centre of Excellence is a NATO-accredited cyber defence hub focusing on research, training and exercises. The international military organisation based in Estonia is a community of currently 20 nations providing a 360-degree look at cyber defence, with expertise in the areas of technology, strategy, operations and law.
