「敵基地攻撃」運用開始　熊本・静岡に長射程ミサイル|47NEWS（よんななニュース）

This page reports that Japan's Ministry of Defense began operating its counter-strike capability on March 31, 2026, allowing self-defense attacks before an opponent launches missiles. Long-range missiles capable of striking outside enemy air defenses were deployed for the first time at Ground Self-Defense Force bases in Kumamoto City and Shizuoka Prefecture. The government claims this represents "unavoidable necessary minimum self-defense measures" consistent with pacifist defense policy, but risks violating international law. Defense Minister Koizumi emphasized strengthened deterrence, though no public briefings are planned, prompting local officials to demand better explanation.
