Rakuten is a major Japanese e-commerce company that plans to conduct all business operations in English by 2012. This includes holding board meetings and creating internal documents in English only. The goal is to expand internationally to 27 countries and increase annual sales. While using English may help employees improve skills and opportunities, some risks include missing talents from those with weaker English abilities and potential communication issues within companies. Rakuten aims to become the top global internet company with this strategy.
