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." "Get Things Done" people are absolutely committed to reaching their goals. With enough determination and effort -- by being a Get Things Done person -- you can achieve anything. 2. Passionately Professional Rakuten is an organization composed of true professionals. Real professionals in any field? Whether in sports, the arts, science, business or anything else? Only reach the top because they have the self-discipline to develop and improve themselves continuously. Only by consistently working many times harder than our competitors can we consistently win. 3. Hypothesize - Practice - Validate - Shikumika Success in business depends on making and executing concrete specific action plans. 4. Maximize Customer Satisfaction Rakuten is first and foremost a service company. We're proud to serve our customers and we ceaselessly seek to improve their experience. 5. Speed!! Speed!! Speed!! The Internet makes the window of opportunity for every small business. Accomplish in one month what it takes other companies a year to do, because we can only win by being many times faster than our competitors.
