Japan and South Korea Resume First Naval SAREX in Nine Years
On June 7, 2026, the Japan Maritime Self-Defense Force and Republic of Korea Navy conducted their first bilateral search and rescue exercise in nine years, west of Japan's Goto Islands. The drill included tactical data sharing, cross-deck helicopter operations, and photo exercises. It follows a 2018 radar-lock incident that froze defense ties, with recovery beginning at the 2024 Shangri-La Dialogue and formalization in January 2026. The exercise signals improved interoperability amid North Korea's nuclear advances and China's naval expansion, though historical tensions and stalled ACSA negotiations persist.

Japan and South Korea Resume SAREX After Nine-Year Hiatus
On June 7, 2026, the Japan Maritime Self-Defense Force (JMSDF) and the Republic of Korea Navy (ROKN) conducted a bilateral Search and Rescue Exercise (SAREX) west of Japan's Goto Islands, the first such drill since 2017. The exercise involved the JMSDF Kongo-class destroyer JS Kongo and an SH-60K helicopter, and the ROK Navy's Cheon Wang Bong-class tank landing ship ROKS Cheon Ja Bong. Activities included search-and-rescue operations, a LINKEX, cross-deck helicopter operations, and a PHOTOEX. The resumption follows a nine-year hiatus caused by the December 2018 fire-control radar incident. Defense ties began recovering after ministers agreed on prevention measures at the 2024 Shangri-La Dialogue, and the exercise was confirmed at a January 2026 ministerial meeting in Yokosuka. Japanese Defense Minister Shinjiro Koizumi called it 'the beginning of a new chapter.' The drill enhances interoperability amid regional pressures from North Korea's nuclear advances, China's naval presence, and uncertainty over U.S. commitments. Challenges remain, including stalled ACSA negotiations and historical sensitivities.

The exercise involved the JMSDF Kongo-class Aegis destroyer JS Kongo and an SH-60K helicopter, and the ROK Navy's Cheon Wang Bong-class tank landing ship ROKS Cheon Ja Bong. Activities included search-and-rescue operations, a LINKEX for tactical data sharing, cross-deck helicopter operations, and a PHOTOEX. The resumption follows a prolonged freeze in naval cooperation after the December 2018 fire-control radar incident. Ties began recovering after defense ministers agreed on recurrence-prevention measures at the 2024 Shangri-La Dialogue, and the SAREX was confirmed at a January 2026 ministerial meeting in Yokosuka. Japanese Defense Minister Shinjiro Koizumi welcomed the exercise as 'the beginning of a new chapter' in bilateral defense cooperation. The drill reflects renewed focus on interoperability amid regional pressures from North Korea's nuclear advances, China's naval presence, and uncertainty over US alliance commitments. Challenges remain, including stalled ACSA negotiations and historical sensitivities, but the exercise marks a meaningful step in rebuilding practical naval engagement between the two key US allies.
