Overview
- Prime Ministers Keir Starmer and Sanae Takaichi finalised the package on Sunday, announcing more than £18 billion in investment across energy, life sciences and frontier technologies.
- An Offshore Wind Compact is expected to unlock up to £9 billion of Japanese investment to back 5.9GW of floating wind projects that officials say would generate power for about 8 million homes.
- The agreement creates a Frontier Tech Partnership and other links to speed collaboration on AI, semiconductors and quantum work, and includes industry tie-ups such as Rolls‑Royce with Japan’s Atomic Energy Agency and a semiconductor path with Rapidus.
- Leaders reconfirmed support for the Global Combat Air Programme and said an international GCAP contract is expected by the end of June, but the UK has not detailed its financial pledge after Defence Secretary John Healey resigned on June 11, delaying the Defence Investment Plan.
- The deal builds on the 2021 UK‑Japan CEPA and recent joint projects and is billed to create tens of thousands of jobs through factory, grid and life‑science investments such as Eisai’s £48 million packaging facility and Hitachi Energy’s planned hires.
