The United Kingdom and Japan have concluded a landmark investment agreement worth £18 billion, officials confirmed this morning. The deal, signed by Prime Minister Rishi Sunak and his Japanese counterpart Fumio Kishida in London, is intended to deepen economic ties and signal the UK’s post-Brexit pivot towards the Indo-Pacific region.
The agreement encompasses a broad range of sectors, including financial services, clean energy, and advanced manufacturing. Under the terms, Japanese firms such as Nissan, Hitachi, and Mitsubishi have committed to expanding their operations in the UK. This is expected to create over 3,000 new jobs in northern England and Scotland.
Both leaders framed the deal as a strategic partnership. Sunak described it as “the next chapter in a historic friendship,” while Kishida emphasised the shared values of market democracy and free trade. The investment package is the largest bilateral deal Japan has signed with a European nation since the 2016 Brexit referendum.
Analysts view the agreement as a counterbalance to the UK’s diminished access to EU markets. The Office for Budget Responsibility has previously estimated that Brexit will reduce long-term trade by 15 per cent. This deal partially offsets that loss by deepening relations with a major non-European economy.
The investment includes £5 billion in green hydrogen projects, £3 billion in digital infrastructure, and £2 billion in defence-related technology. A joint committee will oversee implementation, with the first progress report due in September 2025.
Critics have noted that the deal lacks binding targets and does not address trade in services, which accounts for 70 per cent of the UK economy. Nonetheless, the government insists the agreement is “ratified and operational immediately,” providing a tangible post-Brexit success story.
