Japan-related vessel passed Hormuz Strait on June 19, MOFA says

On June 19, 2026, the Ministry of Foreign Affairs (MOFA) of Japan confirmed that a Japan-related vessel, carrying three Japanese crew members, successfully passed through the Strait of Hormuz and exited the Persian Gulf. This development marks a significant milestone for Japan, which has long advocated for the free and safe navigation of vessels through the strategic waterway.

The vessel, which had been retained in the Persian Gulf, is now en route to Japan. MOFA emphasized that the passage is a positive development, particularly in terms of ensuring the safety of Japanese nationals and maintaining stable maritime trade routes. Japan has consistently urged Iran to guarantee unhindered and secure passage for all vessels through the Strait of Hormuz, a critical global energy transit corridor.

Recent maritime intelligence indicates increased commercial activity in the region, with 26 vessels transiting the strait on June 17, 2026, including a mix of Iranian, Comoros, and Panama-flagged cargo and tanker vessels. While 11 vessels operated without AIS signals, satellite imagery and other monitoring tools were used to track their movements. The reactivation of AIS signals by several Iran-flagged tankers and the movement of sanctioned vessels suggest preparations for an anticipated easing of tensions and potential sanctions relief.

The Japan business community has expressed cautious optimism about the reopening of the strait, though uncertainties remain regarding long-term stability of the region. As Japan continues to monitor the situation, it remains committed to advocating for the safety and security of its maritime interests.
