The wealth and success of Jeremy Hunt — newly appointed to the role of U.K. foreign secretary, and one of the country's wealthiest politicians — can be traced, at least in part, to his experience of and connection with Japan.

A fluent speaker of Japanese, last year he reportedly pocketed £14.4 million from the sale of a company he got the idea of cofounding after spending two years studying the language while teaching English in Japan in the early 1990s.

The company, Hotcourses, runs websites that list educational courses for students around the world, and was bought for £30.1 million by Australian firm IDP Education when Hunt was health secretary.
