The present research applies the Theory of Harmony through Holistic Engagement to the foreign policy of Japan. As the third largest economy in the world and 이ie of the most highly dev이oped countries in the world, Japan is a major international power. Most analysts interpret Japan's foreign policy through the lenses of realist, exceptionalist, or liberal institutionalist approaches. All the previously mentioned approaches tend to be based on etic studies conducted from the point of view of outsiders. The present interpretation of Japanese foreign policy applies an emic model based on primary sources from the Greater East Asian region and concludes that the Model of Harmony through Holistic Engagement shows considerable explanatory traction in interpreting the direction and development of Japanese foreign policy, in particular in the last two to three decades.
