日本国憲法と安全保障 : サイバー戦の視点から  [in Japanese] The Japanese Constitution and National Security in Terms of Cyber Warfare  [in Japanese]

It seems that wars in the 21st century are mainly in the form of Cyber Warfare rather than a more conventional style of confrontation. Cyber Warfare breaks out without declaration. Therefore, under the current Japanese legal system it is difficult to prevent Cyber Warfare, which is fought in the lawless zone called Cyberspace. If there were any legal regulations, such as international treaties, these laws would be broken easily with the new technology that is available. This paper tries to analyze how different nations tackle Cyber Warfare and how Cyber Warfare could be interpreted legally. It also makes several how suggestions on the Japanese defense policy against Cyber Warfare.
