What Is Kuwa Matcha?
Kuwa Matcha is crafted from stone-ground mulberry leaves — a plant long cherished in Yamanashi, Japan for its deep green color, earthy flavor, and extraordinary wellness properties. It whisks like matcha, layers beautifully into lattes, and brings a quiet clarity to every moment of your day. Naturally caffeine-free.
Also known as: Mulberry Tea, Kuwa Tea, Kuwanacha, 桑茶 (Kuwa Cha), Mulberry Leaf Powder. If you've been searching for a caffeine-free matcha alternative or mulberry leaf powder — this is it.
Origin & Heritage
Yamanashi Prefecture is not just where we farm — it is where Japan's mulberry heritage began. For centuries, this region was the heartland of Japan's silk industry, which depended entirely on the mulberry leaf. No other region in Japan has a deeper, longer relationship with this plant.
Yamanashi has been growing mulberry longer than almost anywhere in Japan, with knowledge passed down through generations of farming families.
Our mulberry is grown in the clean mountain air of Yamanashi with deep attention to soil, timing, and craft. While not certified organic, we grow with the highest standards and full transparency.
Recognized by the Japanese government for excellence in agricultural products — a rare honor that reflects decades of dedication.
Why It Works
Mulberry leaves have been prized in Japanese wellness for centuries. Modern research is beginning to reflect what Yamanashi farmers have long understood.
1-deoxynojirimycin (DNJ) is found almost exclusively in mulberry. It supports a healthy blood sugar response after meals — something no regular matcha can offer.
Morning, afternoon, evening, before bed. No sleep disruption, no jitters, no crash. Just a calm, grounding sense of wellness, whenever you want it.
Mulberry leaves are dense in flavonoids, polyphenols, and chlorophyll — powerful antioxidants that support daily health and vitality.
With zero caffeine, Kuwa Matcha is a nourishing choice for expecting mothers who want to maintain a healthy green tea habit without the worry.
