Overview
- Defense Minister Shinjiro Koizumi said Type-03 medium-range surface-to-air missiles are slated for Camp Yonaguni in fiscal 2030, with timing contingent on facility development.
- This marks the first specific deployment window since plans to bolster the island’s air defenses were announced in 2022.
- Upgrades to the Type-03 system include features designed to counter hypersonic glide vehicles, according to previously released ministry materials.
- The ministry will brief Yonaguni residents next week; a roughly 100-person missile unit is planned, the camp had about 230 personnel as of March, and live-fire training will not occur on the island.
- The step follows months of friction with China, which has imposed export curbs and discouraged travel after Prime Minister Sanae Takaichi’s Taiwan remarks; Yonaguni sits about 110 km east of Taiwan and complements a broader Nansei build-up including Ishigaki’s 2023 missile base.
