This paper examines the concept of “derisking” and how the Japanese Economic Security Promotion Act (ESPA) has responded to it within the framework of deterrence theory. It explores how ESPA allows deterrence by denial against economic coercion by other states and is itself a derisking measure. It contends that deterrence by denial, which means reducing dependency and improving resilience, could include stockpiling strategic materials, diversifying sources of supply, developing alternative materials, and developing alternative products. However, this paper argues that there is a need to strengthen the mechanism for collaborative deterrence by denial, such as the “Coordination Platform” presented at the G7 Hiroshima Summit. As for other forms of deterrence, such as institutional deterrence and deterrence by punishment, their effectiveness is insufficient, and they face many implementation problems. Therefore, this paper argues that the most optimal derisking strategy at this point is the combination of ESPA and the “Coordination Platform” to strengthen the capabilities of deterrence by denial.
