Of all the gifts that tennis has given me over the years, the greatest, without a doubt, has been the people I've met along the way: my friends, my competitors, and most of all the fans who give the sport its life.

My country is a country of teachers. It is therefore a country of peace. We discuss our successes and failures in complete freedom. Because our country is a country of teachers, we closed the army camps, and our children go with books under their arms, not with rifles on their shoulders. We believe in dialogue, in agreement, in reaching a consensus. We reject violence. Because my country is a country of teachers, we believe in convincing our opponents, not defeating them. We prefer raising the fallen to crushing them, because we believe that no one possesses the absolute truth.

Absolutely. My friend Charlie Lutes said the most we can do for ourselves is to take that dive within twice a day, bringing out more and more of that consciousness within and that consciousness has qualities, qualities of intelligence, creativity, happiness, love, energy, power, peace. All these things you’re gonna get more and more of. You cannot lose.

Tree planting became a natural choice to address some of the initial basic needs identified by women. Also, tree planting is simple, attainable and guarantees quick, successful results within a reasonable amount time. This sustains interest and commitment.

I want to emphasize the deep gratitude I feel toward my dad. He is my mentor, who shaped me into the person I am today.

My answer may have surprised some in attendance at the meeting: I don’t have a role model or sensei. Or to be more precise, I don’t have a single teacher. Instead, I take it upon myself to learn from everyone around me. If we open our eyes, we may find that everyone can be our teacher.

My “act first” process is not foolproof. It can result in mistakes. In other areas of my business, we’ve changed policies that drew criticism from our customers, launched services too early, and pursued acquisitions that failed to close. But I consider these necessary risks, taken in the pursuit of innovation. In business, there will always be ideas that fail and projects that disappoint. But we learn these things by acting.

The key to success is not perfection. It’s knowing yourself.

Of course, my decision faced plenty of criticism. One of my fellow Japanese CEOs went so far as to call the plan “stupid” – notable, in a country where executives do not generally criticize one another in the press. Clearly, I would have to fight an uphill battle for cultural acceptance. But I was not deterred. A seismic shift demands that we adapt to a new landscape, and a seismic economic shift is exactly what Japan has undergone in recent decades, driven by the forces of globalization and digitization. The only way to compete in this interconnected internet age is to speak the language of the market – and that language is English.

As an entrepreneur, I am the sort of person who prefers to understand things in an intuitive way and make top-down decisions. I have previously referred to the process by which I make decisions as a game of catch between my left and right brain.
