This article addresses a neglected area in Japan–Malaysia bilateral relations: democracy support. While Japan has established itself as a rising democracy supporter after the Cold War and more so in the 21^st century, the country has provided Malaysia with only regime-compatible low-end assistance. Maintaining distance from pro-democracy actors, Japan continued giving de facto support to the semi-authoritarian government in Malaysia before the 2018 general election. There are two main causes: First, Japan emphasized democracy in its diplomacy with the intention of expanding its international influence and differentiate its diplomacy from that of China, rather than to promote democracy out of normative commitment. With a view to obtaining respect from and strengthening relations with state actors, Japan sought to nurture friendly relations with the Malaysian government despite its semi-authoritarian nature. Second, Japan saw elections as the most critical institution for democracy and did not intend to address the weak civil liberties in Malaysia. These two factors led Japanese projects to focus on the capacity building of public administrators as state actors rather than pushing for political change. Hence, Japan’s diplomacy and foreign aid to Malaysia have helped stabilize the status quo instead of supporting democratic diffusion.
