From one particular piece of the sky an unclassifiable signal sometimes recurred and my brain started to say: “You’ve seen something like this before, haven’t you? You’ve seen something like this before from this bit of the sky , haven’t you?” I got out previous recordings from that bit of sky. It often wasn’t there, but when it was, it was keeping its place amongst the stars.

I don’t think that is tough, because if you have an idea of something meaningful to communicate, you can move forward on that. You might not be successful in communicating what you want to communicate, but at least you have an idea of something that needs to be said, or something that you think should be said, and I think you go from there.

I think it’s a combination of being a good listener, trying to understand what lies beneath the surface. And I mean that in the most literal sense.  It could be a cultural institution. It could be an enterprise. It could be a site. It could be the culture of feng shui in an Asian society. The things that you can measure and the things that you can’t measure. And it’s about drawing on the best of diverse skills, the reality that an architect cannot design and realize a building independent of engineers, skilled engineers, structural engineers, environmental engineers. So for me, it’s about harnessing the creative energies. It’s not about designing a building and handing it out and saying, “You make it stand up. You make it warm. You make it cool.” It’s about getting those skills in unison.  The analogy is perhaps a round table, which is non-hierarchical. That doesn’t mean to say that you don’t have strong leadership. Obviously, you have to have that; otherwise, it’s designed by committee. So it’s answering the material needs and providing an element of surprise, something that perhaps nobody believed might be possible to add. And it’s not about money. Quality is an attitude of mind. It’s not about how much you spend. It’s about how wisely you spend. You’ve really got three ingredients. You’ve got material resources, money; you’ve got time, and in many cases, time is money; and you’ve got creative energy. And it’s the creative energy that is going to make the difference in terms of those other ingredients.

An idea comes. Scripts are organised ideas. When you read a script, it comes alive in your head. And that aliveness in the head is like seeing it and hearing it and knowing it. Or if an idea comes from outside, boom, you catch it in your brain and you see it and you hear it, and you know it. You sometimes fall in love with these things. All you do in cinema is translate those ideas. They talk to you, so you just stay true to the idea and translate it as good as you can.

When I asked for advice on how to start such a business, many senior executives told me, "You can't possibly succeed doing what big companies have failed to do."

My job hunting days were at the height of the bubble economy. At the time, I was focused on joining big corporations and had no intention of myself becoming an entrepreneur. I started working at a major bank with a vague idea that I wanted "a job that would take me around the world."

What I’ve come to realize is this: Optimism is more than just a feeling; it’s a strategic approach. And when navigating uncertainty, setbacks and change, it’s one of the most powerful tools in our arsenal.

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.

In Rakuten's case, adjustment certainly took time. At first, meetings often felt awkward. The first board meeting after the Englishization decision took four hours to complete – double the normal duration. But whenever executives asked if they could say certain things in Japanese, I told them no. I knew that the challenge would pay off – and it has.

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.
