[^1]\n\nJapan's Prime Minister Sanae Takaichi presented a preliminary fiscal year 2027 defense budget request to the Diet that includes intention to equip Japanese forces with an underwater-launched high-survivability missile. [^2]\n\nInstead of the Defense Minister, Japan will send Atsushi Ando, a deputy-level official known as the Defense Policy Advisor, to the security dialogue. [^3]\n\nKoizumi Shinjiro visited the Yasukuni Shrine on Liberation Day, May 15, which prompted a strong protest from the South Korean government. [^4]\n\nSouth Korea's Ministry of Foreign Affairs summoned the Japanese Ambassador to Seoul, and the Ministry of National Defense summoned the Defense Attaché to protest the shrine visit. [^5]\n\nJapan and South Korea are concerned that Russia has assisted North Korea in developing submarine-launched nuclear missile capability as payment for North Korean help in the war against Ukraine, which could enable North Korea to launch a ballistic missile with a nuclear warhead from a long-range nuclear-powered submarine. [^6]\n\nNorth Korean leader Kim Jong Un inspected an 8,700-ton submarine under construction in December 2025, according to the Korean Central News Agency. [^7]",
