Cuzen Matcha was dreamed up by two lifelong friends who want to share fresh matcha with as many people as possible.

Eijiro Tsukada  塚田英次郎

Eijiro Tsukada

Co-founder & CEO

Eijiro (Ey-jee-roh) was born and raised in Tokyo. He was educated first at the University of Tokyo—where he and Oki became friends—and then at the Stanford Graduate School of Business. After graduating, he dedicated over a decade to the tea business in both Japan and the US. He led the successful launch of Iyemon Toku-cha (part of FOSHU: Food for Specified Health Uses) in Japan and later opened Stonemill Matcha in San Francisco—now one of the busiest matcha cafés in the world. 

Eijiro started Cuzen Matcha to pursue his passion for making authentic matcha accessible to more people.

Oki was born and raised in Yame, Japan, surrounded by many tea farmers. He moved to Tokyo for university, where he met Eijiro on their very first day on campus. After graduating from the University of Tokyo, Faculty of Medicine, Oki worked as a data scientist before founding his own marketing data science company. 

Moved by Eijiro’s passion for matcha backed by science, Oki co-founded Cuzen Matcha with a vision to establish a sustainable tea production ecosystem in Japan.

“We’re more tea company than tech company.”

Start fresh. Stay fresh.

With centuries of tradition, matcha isn’t an easy place to do something new. But like so many things in our world, a different approach is needed.

We created new technology inspired by ancient techniques. And support modern tea leaf production that replenishes the soil while providing greater financial stability for farmers. So we all can enjoy the freshest cup of matcha that benefits our bodies, minds, and planet for a long time. 

 We want to free up how people think about, prepare, and enjoy matcha. We’re here to bring authentic matcha culture with us into the future.

A refreshed mind and fresh thinking starts with a fresh cup of matcha.


Bringing authentic matcha into people’s daily lives with ease and an open mind.

Our Vision

Through matcha, we’re working to build a sustainable world, where people live in harmony with each other and with the earth.

Our Commitment to Sustainability

1. Sustainable Tea Farming

Only a small percentage of Japanese tea is grown organically while most tea farmers still use chemical pesticides and fertilizers. We believe that matcha should be organic, not only for the ecosystem’s continued health but also for your own, as matcha leaves are ingested entirely.

We carefully source our shade-grown organic leaves from independent tea farms in Kagoshima prefecture, Japan. The farms, located in the Kirishima area (literally “fog island”), provide a terrific natural environment for organic Japanese tea growing. Maintaining and replenishing the ecosystem is a year-round job; the farmers strategically apply organic compost, fertilizer, along with natural pest control. At the moment, our partners are among the small number of Japanese farms that are fully organic. It’s our hope that as Cuzen Matcha grows, we can spread beneficial tea farming practices throughout Japan.

2. Sustaining a Tea-Growing Tradition

Many Japanese tea growers are advancing in age. At the same time, those tea farmers, who have dedicated themselves to high-quality tea production for many years, are suffering from decreasing domestic demand for high-quality tea. People in Japan now drink more bottled green tea, which only requires standard-quality tea. Every year, aging tea growers abandon their tea farms since it is harder to make a profit—and a year later, those abandoned tea fields become unusable.

We are doing our best to bring authentic, high-quality, organic matcha into people’s daily lives. As demand for this delicious, healthy energy source grows globally, high-quality tea farms in Japan will gain greater financial stability, which will make sure the careful practice and culture of farming isn’t lost in Japan.

3. Sustainable Packaging

Coffee pod systems are common for people at home or in the office. There’s also more and more options available for people to buy green tea in plastic bottles. However convenient these systems may seem initially, they produce plastic waste with every drink.

We designed Matcha Maker and Matcha Leaf to work together and limit plastic waste. Without using a pod system, we prepared tea leaves specifically to fit the compact ceramic mill. By doing this, we can reduce unnecessary plastic waste. If you use our big 60g bag, one plastic bag can make up 60 cups, which is much more environmentally friendly than the pod system. Eliminating plastic waste completely is a big but necessary challenge in the modern world but everyone can contribute by reducing their waste to some extent.
