“The United States will extend its cyber defense umbrella over Japan, helping its Asian ally cope with the growing threat of online attacks against military bases and infrastructure such as power grids,” Reuters reports.  

“Both the United States and Japan are wary of cyber threats, including potential attacks from China or North Korea. While the United States is investing heavily in building a force to counter and retaliate against online attacks, Japan, which hosts the biggest U.S. military contingent in Asia, has been slower to buttress its cyber defenses.”  

“The Japanese military’s cyber defense unit has around 90 members, compared to more than 6,000 people at the Pentagon.”
