The United Kingdom and Japan are preparing to finalize a major UK Japan investment deal worth more than £18 billion ($24 billion), aimed at boosting infrastructure, clean energy, and advanced technology sectors. The agreement is expected to be announced during a meeting between UK Prime Minister Keir Starmer and Japanese Prime Minister Sanae Takaichi.
The deal includes a five-year Japanese investment pipeline exceeding £9 billion focused on infrastructure and financial services. Both countries also plan to unlock up to £9 billion in funding for offshore wind energy projects, strengthening their clean energy transition strategies.
A major component of the UK Japan investment deal is offshore wind development, which is expected to support 5.9 gigawatts of energy capacity. These projects will be located across Scotland and the Celtic Sea, contributing significantly to the UK’s renewable energy targets.
In addition to energy investments, the two countries will launch a new technology partnership covering artificial intelligence, semiconductors, and quantum computing. The initiative aims to deepen collaboration in critical future technologies and strengthen supply chain resilience.
Several major companies, including Hitachi Energy, Rolls-Royce, and Eisai, are also expected to announce new investments and joint ventures. These will span power grid expansion, nuclear technology development, and life sciences innovation.
The agreements are expected to be signed during Prime Minister Takaichi’s visit to the UK, ahead of the upcoming G7 summit in France scheduled for June 15–17. Officials say the timing highlights growing cooperation between the two nations in both economic and strategic areas.
Overall, the UK Japan investment deal reflects a broader effort to align economic growth with clean energy transition and technological innovation, while also creating tens of thousands of new jobs across both countries.
