Abstract: The author of this thesis has made an in-depth study of the Japanese cyber defence capability and its unique background through research on the Japanese constitution and laws, domestic government agencies responsible for cyber defence, and alliance with the United States (US) after World War II. In addition, through the lens of cyber power theory, a comparative case study on national strategies with countries that are reportedly successful in overcoming disadvantages and adversities in the real world was conducted. Specifically, two countries were selected for comparison: Estonia and South Korea. This thesis seeks to illuminate ways to promote the transformation of Japan's cyber defence capabilities and effectively enhance its cyber power by leveraging learnings from other countries in the process of examining the research questions.
