How Rakuten’s Shift to English Transformed Its Culture

In 2010, Japan’s largest e-commerce platform Rakuten was rapidly expanding into global markets when CEO Hiroshi Mikitani made a surprising announcement: Rakuten’s internal language would be changing to English. That meant that all meetings, emails, and other communications would have to be conducted in English. The company’s employees had two years to become proficient in the language or be demoted. In this episode, Harvard Business School professor Tsedal Neeley discusses her case, “Language and Globalization: ‘Englishnization’ at Rakuten,” and explains why Mikitani introduced this new mandate and what results it achieved.
