The paper examines the root causes of Japan's rapid shift to foreign policy activism. To explain the causes, Idevelop the so-called "perverse political accountability" approach. Specifically, the approach claims that a growing security challenge from China and North Korea, and US policy favoring Japan's foreign policy activism structure.Japan's domestic political condition that the majority of Japanese people become more conservative and nationalistic. Such shift in the Japanese people's preference has been both creating and reinforcing a perverse accountability by which the leaders or parties willing to adopt hard-line foreign policies are better off electorally while the leaders or parties remaining soft-line on foreign affairs are worse off. The perverse accountability not only leads to a severe partisan imbalance between the conservative parties and the leftist parties, but also gives the most conservative party, e.g., the Liberal Democratic Party (LDP), a greater chance of coming to office and of pursuing assertive foreign policy they favor. Thus, the perverse accountability is at the center of current Japan's turn to foreign policy activism. This finding contributes to an enhanced understanding for Japan's shift to assertive foreign policy.Keywords: Japan, foreign policy activism, China, North Korea, the US, perverse political accountability
PuzzleThe world has wondered why Japan is moving so rapidly into foreign policy activism. Japan, whose foreign policy was quite peaceful and generous in development aid, disaster relief and peacekeeping, has grown increasingly hawkish in recent decades. Japan's foreign policy leaders, regardless of their partisan differences, have not hesitated to show their growing commitments to a series of assertive foreign policies, such as proactively responding to growing threats from China in the East and South China Sea, preventing North Korea's missile threats, exercising the right of collective self-defense, making it easier for the Diet to propose revisions to the war-renouncing Article 9 of the Constitution, increasing a more proactive role for the Self-Defense Force (SDF) overseas, and downplaying its World-War II (WWII) era crimes.
