According to CoinMeta, and as reported by the Japan Broadcasting System, regarding the revision of the "Three Security Documents," Japanese Defense Minister Toshiro Kono stated that with the continuous decline in Japan's population, it is not easy to ensure that the Self-Defense Forces (SDF) have a sufficient number of members. He hopes to study ways to break down the organizational barriers between the Ground Self-Defense Force, the Maritime Self-Defense Force, and the Air Self-Defense Force, and to explore new organizational structures in order to enhance Japan's defense capabilities.
