Yemen’s Ambassador to Japan, Adel al-Sunaini, met Japan’s State Minister of Defense, Masahisa Miyazaki, in Tokyo on Monday for talks on bilateral relations and on the deteriorating security of the shipping lanes off Yemen’s coasts, according to the state news agency Saba.
Al-Sunaini set out the threats now facing navigation in the Red Sea, the Gulf of Aden and the Bab al-Mandab Strait, and argued that the disruption reaches well beyond the region into global trade, supply chains and energy security. He described the danger as a product of escalation by the Houthi movement, which the Yemeni government characterises as an Iran-backed force, and pressed the case for international coordination to protect the routes. The ambassador also thanked Japan for its support of Yemen’s unity, security and territorial integrity, and for its backing of peace efforts.
Miyazaki, for his part, restated Japan’s support for Yemen’s unity, security and stability, for the Yemeni government and people, and for efforts to strengthen maritime security and freedom of navigation, Saba reported. No new agreement or commitment was announced.
The choice of interlocutor is not incidental. Japan is among the countries with the most direct exposure to instability in these waters. It imports the overwhelming majority of its crude oil from the Gulf, and much of the container traffic between Asia and Europe on which Japanese manufacturers depend passes through Bab al-Mandab and the Suez Canal. When that corridor becomes unsafe, carriers route around the Cape of Good Hope instead, adding roughly ten days and substantial fuel cost to each voyage and tightening vessel availability across the whole network. The effect is felt in freight rates and delivery schedules long before it appears in headlines.
Japan also has a physical presence nearby. Its Self-Defense Forces have operated a facility in Djibouti since 2011, established to support counter-piracy patrols in the Gulf of Aden, and Japanese naval vessels and maritime patrol aircraft have worked in the area for years alongside other international deployments. That history gives Tokyo both an operational stake in the security of the approaches to Bab al-Mandab and a working familiarity with the multinational arrangements that police them.
The relationship extends beyond security. Japan has been a consistent donor to Yemen, and Japanese funding supports a seawater desalination project in Aden that Yemeni officials have described as important to the city’s water security and have sought additional money to complete. Development assistance of that kind is one of the few channels through which Japanese policy reaches Yemeni civilians directly, and it gives Tokyo a reason to follow the political situation in the south closely.
Bab al-Mandab itself is a narrow passage between Yemen and the Horn of Africa, and it functions as the southern gate of the Red Sea. Everything transiting between the Indian Ocean and the Suez Canal must pass through it. That geography has made the strait one of the recognised chokepoints of global shipping and has given whoever controls the adjoining coastlines an influence out of proportion to their economic weight. It also explains why the coastal strip in Taiz province has been fought over so persistently.
The current escalation has given the ambassador’s warnings immediate substance. The Red Sea port of Mokha, on the Yemeni side of the approaches to the strait, suspended commercial and maritime operations this month after repeated missile strikes, with its director reporting more than twenty-five impacts and officials estimating losses in the region of sixteen million dollars. Earlier attacks on the same port killed civilians and members of the security forces. Marine insurers have raised premiums for Red Sea calls in response, and some carriers have withdrawn from the route.
Diplomatic activity around Yemen has picked up accordingly. The United Kingdom has warned of dangerous Houthi escalation and reaffirmed its commitment to Yemeni sovereignty, and Yemeni officials have raised the attacks in a series of meetings with Western and regional counterparts over the past fortnight. The United Nations Special Envoy for Yemen has warned that the country faces its highest risk of a return to large-scale conflict since the truce agreed in April 2022.
Yemen also has an interest in the framing itself. Presenting the conflict as a maritime security problem rather than only a civil war widens the group of governments with a stake in its resolution, and it aligns Sanaa-related diplomacy with the concerns of shipping states, insurers and energy importers. The risk is that international engagement narrows to protecting vessels while the political process and the humanitarian response receive less attention.
What such meetings can deliver is limited and worth stating plainly. Statements of support do not change the balance on the ground, and the practical tools available to Yemen’s partners, principally naval escort, sanctions designations and diplomatic pressure through regional intermediaries, have not so far persuaded the Houthis to stop. The Yemeni government’s strategy is nonetheless consistent: keep the maritime dimension in front of governments whose economies are exposed to it, on the argument that a threat to global shipping generates attention that Yemen’s internal crisis alone does not.
Tokyo has offered words rather than commitments. For an ambassador working to keep Yemen visible in a crowded diplomatic field, that is a routine outcome. Whether it translates into anything more concrete will depend less on what was said in Monday’s meeting than on how far the disruption in the Red Sea continues to spread.
