Seiun (星雲 - "Nebula") by Yamamasa Koyamaen is an intense, velvety koicha-grade ceremonial matcha that delivers full-bodied umami with robust creaminess and natural sweetness—a premium blend crafted for discerning matcha enthusiasts seeking depth and sophistication. Named after the Japanese word for "nebula," which beautifully merges "star" and "cloud" into one celestial concept, this matcha embodies the harmonious union of contrasting elements: intense yet smooth, robust yet sweet, traditional yet versatile.

Founded during the Edo era, Yamamasa Koyamaen is a prestigious tea house with over 300 years of heritage that still owns and cultivates the same tea gardens in Uji as their ancestors did centuries ago. Their matcha specialists treat tea-making as an art form, prioritizing the finest raw ingredients and meticulous cultivation techniques to achieve perfect taste. Yamamasa Koyamaen's motto is simple yet profound: to deliver fine tea with harmonious, fresh flavor that honors tradition while serving modern tea lovers.

Seiun showcases intensive, creamy flavors with toasted seed aromas and a characteristic, lingering aftertaste. While it shines brightest as koicha (thick tea), revealing its full complexity and velvety texture, it also performs beautifully as usucha (thin tea) with intensive creaminess. This lighter, sweeter profile compared to Yamamasa Koyamaen's Tennozan makes it an approachable yet premium choice for both traditional tea ceremonies and elevated daily rituals.
