Mayor of London Boris Johnson has headed to Japan for a trade trip, and fintech will be one of the key things he is promoting whilst there.

Japan was the fourth largest investor in London in 2014, with trade between Japan and London totalling almost £950m.

In his three day visit, Johnson will be keen to build on this past history of trade and business with Japan, with the Mayor planning to highlight investment and business opportunities in London’s £20bn fintech sector.

Helping Johnshon push the fintech agenda in Japan will be the government’s fintech envoy, and chair of Tech City UK Eileen Burbidge, as well Barclays chief digital officer Derek White.

Johnson will visit Tokyo, Osaka and Yokohama during the three day trip, and other tech topics, such as bio-science, will also be on the agenda.

Johnson said: "This is our chance to loudly bang the drum for London, strengthen our ties with Japan, and secure the long standing relationships we need to create an abundance of opportunities for Londoners and the people of Japan to work more closely and collaboratively in the future."

The trip is designed to boost investment in the capital, which is already the top Japanese investment destination in Europe. 30% of Japanese investment in Europe goes to London.
