As the internet becomes a given in all of our lives, and a part of the world’s essential infrastructure, Rakuten is thinking about what that change means for us all, 10, 20 or 30 years from now. We started out as champions of innovation in e-commerce. We were the first company globally to successfully launch a merchant-focused e-commerce marketplace, one that is now the platform of choice for more than 40,000 merchants and a leader in our home market of Japan. We were the first to launch a financial business from a position of strength in e-commerce and now we are gaining fast on Japan’s traditional financial sector giants, with credit card membership that puts us in the top three and innovative payment services that once again put us in the forefront of providing best-in-class services to small and medium-size businesses around Japan. As Rakuten has matured over our first twenty years, we have also become increasingly aware of the responsibility that comes with innovation and industry leadership. We have lead Japan on improving data management and privacy standards, encouraging diversity and inclusion and developing the next generation of responsible tech entrepreneurs.

Rakuten principles 1. Always Improve, Always Advance There are only two kinds of people in the world: Best Effort people are satisfied with the status “when they fail, they console themselves by saying "I did my best."
