Our Story

Hakusui was founded by two Japanese entrepreneurs, Tetsuro and Yuta, who built their careers in global tech across Tokyo, Singapore, and the U.S. Bay Area.

In the fast-moving tech industry, where efficiency and scale define success, they began to reflect on the Zen spirit they had inherited through tradition.

They came to believe that life is not a goal to achieve, but a process to experience, and that true wellbeing lies in presence and balance.

Japanese culture is more than sushi or ramen. It is subtlety, stillness, and depth.

Matcha is one of its purest expressions.

"HAKU (伯)" represents distinction and quiet nobility, also inspired by the "HACK" culture of Silicon Valley where the two founders built their careers — a mindset rooted in constant experimentation, rapid iteration, and relentless improvement toward something better.

"SUI (翠)" represents a deep, vibrant blue-green that symbolizes nature, clarity, and vitality — the living essence reflected in the rich color of matcha.

Rooted in tradition, refined through modern sensibility.

A matcha brand born at the intersection of Japanese craftsmanship and global perspective - combining the clarity of technology with the calm of tea culture.

For Tetsuro, tea was part of childhood.

For Tetsuro, tea was part of childhood.

His grandmother was a tea ceremony master. He remembers the scent of tatami mats, the soft sound of water boiling, the delicate motion of the bamboo whisk against the bowl.

"Tea is not only about taste", she used to say. "It is about preparing the mind."

Those moments quietly stayed with him.

For Yuta, that same spirit took shape through kendo.

For Yuta, that same spirit took shape through kendo.

His journey began at the age of four, guided by his grandfather. Through years of training, the Zen spirit at the heart of his practice became a foundation he carried into life in the U.S. Bay Area tech world.

Kendo and the Japanese tea ceremony offered a shared lesson: to quiet the mind and be fully present in each moment. While Tetsuro found this through tea, Yuta found it through the sword.

Their paths began in different places, but led them toward the same purpose. They decided to build a brand that would present matcha as it truly is.

Not simply as a luxury ingredient, but as a craft. A product shaped by land, by farmers, by time, and by philosophy.

Who made it.

Where it came from.

And what kind of dedication lives inside a single bowl.

That idea became Hakusui.

If a single cup of Hakusui can bring stillness to someone's busy day,

or help someone far from Japan feel the depth of its culture, then it is already fulfilling its purpose.
