The Japanese government plans to both increase the number and expand the scale of exercises to counter cyberattacks as part of preparations for the 2020 Tokyo Olympics, Kyodo quoted government sources as saying Saturday.

The drills, now held about six times a year and involving central government ministry and agency officials, will be increased to at least 10 a year and expanded to include officials of local governments that are falling behind in cyber security measures.

The 2012 London Olympics official website is known to have been attacked about 200 million times, and Japan is bracing for even more attacks in 2020.
