UK Prime Minister, Rishi Sunak, has agreed new defence and economic deals with Japan in a visit to Tokyo, ahead of the G7 summit in Hiroshima.
Speaking on board the JS Izumo aircraft carrier, the PM announced a partnership featuring closer UK-Japanese co-operation between armed forces, cyber-agencies and semiconductor companies.
He also said Japanese firms would be investing almost £18bn in the UK.
But Labour said foreign investment had plummeted under the Conservatives.
The government is emphasising it sees the region providing economic opportunity for the UK post-Brexit UK, as well as working with Japan and Australia to counter the strategic threat from China.
About £10bn of the investment is coming from trading and investment business conglomerate Marubeni and is earmarked for offshore wind and green hydrogen projects in Scotland and Wales.
Similarly, Sumitomo Corporation intends to inject £4bn in offshore wind projects off the Suffolk and Norfolk coastline.
The government said both the investments would further solidify “the UK’s status as a clean energy pioneer” and would help the UK achieve its net zero target by 2030.
The announcement came as Mr Sunak hosted a reception in Tokyo highlighting the strength of the UK and Japan’s economic relationship ahead of the UK joining the regional CPTPP trade bloc (the Comprehensive and Progressive Agreement for Trans-Pacific Partnership).
The government said Japan was the fifth largest investor in the UK, with trade in goods and services worth £27.7bn last year.
Mr Sunak said the new investment was a “massive vote of confidence in the UK’s dynamic economy” from some of Japan’s top firms.
