Japan is set to play a crucial role in a multinational peacekeeping force in Ukraine, joining the UK’s coalition aimed at securing a post-war settlement between Kyiv and Moscow.
The move comes as part of UK Prime Minister Keir Starmer’s “coalition of the willing,” which brings together key allies to help stabilise Ukraine and deter future Russian aggression. While Japan’s exact role is yet to be confirmed, officials suggest it could involve logistical support, advanced equipment, or military personnel on the ground.
Japan, which has a defence force of around 300,000 troops, has been gradually strengthening its military capabilities in recent years due to growing tensions in the Indo-Pacific region, particularly with China’s increasing aggression towards Taiwan.
Despite its pacifist constitution, Japan has been expanding its defence partnerships with Western nations, including a new security and defence agreement with the UK.
The coalition’s next steps will be discussed at a high-level meeting at the UK’s Ministry of Defence’s Permanent Joint Headquarters in northwest London.
Defence Secretary John Healey will host military leaders from around 30 countries to finalise plans for the deployment of the peacekeeping force, which is expected to exceed 10,000 troops.
The UK and France have already committed to sending forces on the ground, while Japan’s involvement is seen as a strategic move to reduce Russia’s claims that the mission is solely a NATO effort.
Non-NATO countries such as Australia and Japan are expected to play a key role in convincing Russian President Vladimir Putin to engage in peace talks.
Japan’s growing involvement in global security is evident through its recent appointment of a full-time ambassador to NATO and participation in joint military exercises with the UK.
The upcoming arrival of the British aircraft carrier HMS Prince of Wales in Japan for joint drills highlights the deepening defence ties between the two nations.
While some European leaders support the idea of deploying forces in Ukraine, concerns remain over the potential for direct conflict with Russian forces.
Finnish Prime Minister Alexander Stubb has expressed caution, stating that deploying troops without a ceasefire or peace process could be premature.
Former UK national security adviser Lord Peter Ricketts also warned that deploying a European force without US support carries significant risks.
He stressed that for the peacekeeping mission to be effective, the US must provide a clear guarantee of support in case the force faces Russian aggression.
Despite the challenges, the UK government remains committed to leading the coalition and developing a credible strategy to secure lasting peace in Ukraine.
Japan’s participation is seen as a major step forward in building a diverse and effective international force that can help stabilise the region and prevent future conflict.
