Contributing to sustainable
well-being

As human beings, our ultimate aim can be stated simply: to be happy. Human beings are social creatures, unable to live without interacting with others. We believe that the most rational way of turning happiness from a goal into a reality is by maximizing things which bring goodness to others, and minimizing those that do not. We must work to achieve our fullest potential in the environment given to us—in other words, fulfilling our reason for being. While our individual efforts may be small, the combined endeavors of many can bring about large benefits to society that return to us on a personal level.

For the Spiber Group, our every effort from conceptualization to action, are nothing more than a means of maximizing our individual contributions to society. We are driven by the belief that the realization of protein-based materials will allow us to make the biggest positive impact on the world. Science and technology are the powerful tools to get us there, and forming a team—a company—maximizes our chance of success. With long-term vision, we must take the lead and tackle the problems others will not, either because they are deemed too complex or too risky. Our resolve is steadfast, and we are up to the challenge.

Brewed Protein™ as a solution

Humankind’s existence is made possible thanks to the bounty of Earth’s natural resources. The growth of our societies and economies, for example, is driven by the accelerating consumption of fossil fuel stores created over millions of years—consumption which, if not stopped, will eventually lead to their depletion. Accordingly, the question of how we should negotiate humanity’s relationship with nature has never been a more pressing one.

With development grounded in close observation of the natural world, Spiber’s Brewed Protein™ materials are produced through a fermentation process that utilizes sugars and microbes, rather than petrochemical or animal-derived raw materials. With their potential for mainstay industrial use, Spiber believes that Brewed Protein™ materials represent a compelling contribution towards our shared endeavor to create a more sustainable future for humanity and nature, both now and for generations to come.

    Humanity faces a multitude of global issues that must be addressed, but our risk-averse nature inevitably leads us to prioritize projects with myopic, short-term gains. Japan boasts one of the most advanced societies and economies in the world, and we believe corporations in such favorable positions are obligated to take the initiative in solving complex global issues, and provide humanity with a positive vision of the future. We are willing to accept the inherent risks that come with taking on the impossible and shifting paradigms, because we believe this is the way humanity moves forward. Tackling new questions and trying new approaches to old ones is an immensely exciting and fascinating process, and that is what motivates us. We want to push humanity forward. This is the guiding principle that keeps the entire team focused on tackling the pressing problems facing our world.

    Watching my children as they sleep peacefully, I feel a strong desire to see them lead full, happy lives. I believe that the aspiration to end grave environmental destruction, the crisis of limited resources, war, and hateful crimes is part of basic human nature. We should leave behind a sustainable and plentiful society for future generations. On the other hand, when I start to think about the future in earnest, I realize that there is not much time left to achieve this vision. There is no margin for error; no time to exhaust ourselves with excessive, unproductive competition. In order to make the world a better place, it is crucial that we implement solutions quickly and on an unprecedented scale, no matter what the risk. Spiber, in my mind, is the means to that end.
