How the company was founded

Does Japanese society make people happy?

The defining moment came in Mezaki’s teenage years. While studying abroad in Europe, he was deeply struck by the way his peers lived their lives. Unlike Japan, where conformity often prevails, the culture he encountered valued individual expression. These young people were confident in their opinions and lived passionately, enjoying life to the fullest. It was then that a powerful question took root—Does Japanese society truly make people happy? This profound doubt would go on to shape the course of Mezaki’s future endeavors.

Conflicts felt at a major securities firm

After graduating from university, Mezaki joined Merrill Lynch, a leading global investment bank, with an eye toward starting his own business in the future.　However, working at the forefront of the business world left him questioning capitalism itself. He was troubled by the money-driven mentality that dominated the financial industry. Was something essential being lost in the name of business and marketing? This moral conflict led Mezaki to leave Merrill Lynch after five years.

Guiding Principles of Life Found in 100 Countries Traveled

Mezaki embarked on a journey in search of life’s guiding principles. He trained in India, wandered through South America and Africa, and explored the world.　What he discovered was a universal truth: every society exists to enable individuals to pursue happiness. But just as there are systems that foster happiness, there are those that stifle it.　Determined to create a society where individuals can truly seek their own happiness, Mezaki resolved to dedicate his life to guiding Japan toward that vision. Thus ended a decade-long journey across more than 100 countries.

The Future GPSS is Aiming for

“Sustainable Joint Venture.”

In most commercial activities, we inevitably face conflicts of interest. Pursuing one’s own gain often comes at the expense of the other party. This is why GPSS is committed to avoiding conflicts of interest wherever possible and striving to build a sustainable society. At the heart of this philosophy is our partnership with local communities. By leveraging cutting-edge technology and a wide range of expertise, GPSS transforms untapped natural resources in these regions into energy, laying the foundation for sustainable, self-reliant communities. Together with these communities, we operate power plants through joint ventures, ensuring shared benefits and growth. By jointly owning power plants with local stakeholders, we align the interests of the community, GPSS, and society in the same direction.

Transforming a Restrictive Japan from Within the Workplace

GPSS is deeply committed to sustainability within the company itself. A company is the smallest unit of society, and if work cannot bring fulfillment and happiness, a truly happy society cannot exist. To create a sustainable and joyful society through energy projects, we must also pursue fulfilling ways of working. The goal is to shift from “how things should be” to “how we want things to be” and to foster a culture that values freedom over rigid rules. The one guiding principle is the liberation of the “soul,” the smallest unit that defines the self.

To help employees connect with their inner selves and gain a deeper understanding of who they are, GPSS provides opportunities for open dialogue in various forms. Mezaki believes that the more we explore our inner worlds, the closer we come to understanding the universal truths of the world. As a result, each individual can channel their personal desires into energy for their work, turning passion into a meaningful contribution to society. GPSS remains on a long journey toward realizing this vision of an ideal future.
