The Russo-Japanese War was fought well over a hundred years ago and symbolised the rise of Japan, as it defeated Russia by executing a near-perfect limited war strategy. Japan incisively defined limited political objectives and calibrated its war strategy accordingly.

Three key developments unfolded in Japan in August 2018: the Ministry of Defence (MOD) released its annual Defence White Paper; requested a 2.1 per cent increase in the 2019 budget; and instituted an Exploratory Committee on the Future of Self Defence Forces (SDF) with the objective of reviewing the current National Defence Program Guidelines (NDPG) and the Mid-Term Defence Program (MTDP). Analysing these developments in the backdrop of Prime Minister Abe’s top priorities—managing the United States (US)-Japan alliance under the Trump Presidency and delivering on the ‘great responsibility’ of redefining Japanese post-war security orientation—unpacks Tokyo’s key challenges. These are, essentially, balancing between sharing greater burden within the alliance framework to ensure regional security on one hand, and weighing regional sensitivities and deeply fractured domestic constituencies on the other.
