As it faces burgeoning cyber threats from China, North Korea and Russia, Japan is struggling to operationalise its defensive and offensive cyber capabilities. What are some of the financial, legal, and organisational barriers facing Tokyo as it tries to realise its growing aspirations in cyberspace?
Japan is increasing investment in its military cyber capabilities. In the near term, it will grow the personnel numbers of its Cyber Defence Group by one-third, with further restructuring to follow. Like other countries, however, Japan is grappling with the twin challenges of determining what constitutes adequate funding for its cyber aspirations, and clarifying the boundaries between the civil, military and inter-service spheres of cyber responsibilities and operations.
Japan’s cyber capabilities at a glance
The Japan Self-Defense Forces’ (JSDF) Cyber Defence Group (CDG), part of the JSDF’s Command, Control, Communication & Computers (C4) Systems Command, will increase its personnel from 220 to 290 by the end of March 2021. Spending on cyber more than doubled between 2018 and 2019 following the adoption of the 2018 defence strategy, rising from JP¥11 billion (US$100 million) to JP¥25.6bn (US$235m). However, this growth was from a very low base: the 2019 spending figure was less than half a percent of the country’s defence budget. Whether this level of expenditure is sufficient to provide the cyber capabilities Japan seeks is open to question.
