Changes in Security Environment and Japanese Defense Problems

Abstract

In December 2022, the Kishida administration announced a new national security straregy. The document explicitly states that all options will be considered realistically, and none will be ruled out, including the possession of counterattack capabilities that previous administrations refrained from pursuing due to policy decisions, in order to fundamentally strengthen Japan’s defense capabilities. Driving this shift is the evolving regional security environment. China is undertaking a sweeping military modernization program and increasing maritime pressure on Japan in the East China Sea. North Korea continues to advance its nuclearweapons and missile programs,and Russia has labeled Japan as an "unfriendly country" while increasing military activity near Japan.Following the release of the new national security strategy, Japan received strong support from its ally, the United States, for enchancing its defense capabilities. Additionally, support for security cooperation was expressed by the G7, Australia, India, ASEAN, and South Korea.Japan is steadily advancing efforts to strengthen its defense capabilities.
