Japan’s security posture seems to be heading for a dramatic overhaul as it feels compelled to respond to the emerging challenges in the altered security environment in its neighbourhood. China’s belligerence in territorial issues and North Korea’s nuclear and missile tests have awakened Japan to think seriously about safeguarding its own security. It may be recalled that when North Korea fired missiles in the recent past, they flew over Japan’s northern island of Hokkaido, exposing Japan’s vulnerability and to external security threats. This compels Japan to seek means to strengthen its own capability to deter attack from potential unfriendly countries. This was a priority for the Shinzo Abe government and continues to be the same for the Fumio Kishida administration.
