Japan's Ground Self-Defense Force is reportedly pursuing a single network linking anti-ship, air-defense and ground fire commands for defending its southwest islands, in use as early as fiscal 2030. The Defense Ministry is said to have included at least 17.9 billion yen in its next-year budget request, which is a request rather than approved funding.
Citing Nikkei, Taiwan's Central News Agency and Liberty Times reported that the GSDF wants to merge missile and artillery command systems so commanders can see enemy ships, landing forces, incoming missiles and friendly deployments on one electronic map. The command, air-defense and fire systems are currently made by different companies and are not linked.

Japan's stated aims are to cut counterattack delays caused by scattered information, conserve limited missiles and shells on remote islands, and respond to simultaneous attacks while reducing harm to residents.
Japan's rationale and China's position
Japan has long cited the risk of Chinese military action over Taiwan spilling into Japan as a backdrop for strengthening defenses. The reports also noted that Chinese carriers and destroyers often operate in the Pacific near Japan's southwest waters. Tokyo's position is reported to be that such steps are defensive.
China appears not to have publicly responded to this report. However, when Japan outlined plans for a missile unit on Yonaguni Island in February, China was reported to have criticized it, and Beijing has consistently argued that Japan's military buildup in the southwest islands raises regional tension. China's specific position on this matter has not been confirmed.
Uncertainties remain. FY2030 comes with an ‘as early as’ qualifier, and the reports do not say which units will receive the system, at what scale, or whether it will be fully operational by then. The system will reportedly not use AI for combat decisions at first, though AI support for analysis and defense planning is under study.
