Abstract
As China and North Korea aggressively assert their growing capabilities and destabilize the Indo-Pacific region, Japan and other like-minded nations are considering various options to confront the growing threat. Thus, Japan has recently begun to strengthen its military cooperation with the United States, the United Kingdom, Australia, New Zealand, and Canada, all of which are members of the Five Eyes (FVEY) intelligence-sharing group. Extensive intelligence cooperation, however, has continued to lag between Japan and the FVEY members.This thesis therefore examines the factors that have prevented Japan from pursuing a deeper intelligence-sharing relationship with FVEY and whether they remain as obstacles to Japan’s formal ascension to the most extensive and exclusive intelligence-sharing group as a Sixth Eye. The research suggests that three independent variables affect Japan’s intelligence-sharing relationships: 1) increased threat perception, 2) strengthened intelligence institutions, and 3) increased trust with its security partners. Further analysis of these variables reveals that they all affect intelligence sharing differently across time periods. Changes in certain independent variables may not produce noticeable increases in intelligence sharing until decades later. As such, research has shown that Japan’s lack of sufficient institutional protections regarding state secrets remains the primary obstacle to its ascension to FVEY as a sixth member.
