The Story of Yamamasa Koyamaen
Yamamasa Koyamaen is a family-owned tea house deeply rooted in Uji's centuries-old tea tradition. While the exact founding date is not widely publicized, the company has been producing premium matcha for multiple generations, carrying forward the artisanal methods that made Uji famous as Japan's premier tea-growing region. The family's dedication to quality over quantity has earned them respect among tea connoisseurs who appreciate their commitment to traditional craftsmanship. Unlike larger commercial operations, Yamamasa Koyamaen maintains direct oversight of their entire production process, from cultivation to final packaging, ensuring consistency and authenticity in every tin.
Traditional Craftsmanship
Shade Growing
20-30 days before harvest
Hand Picking
First flush spring leaves
Stone Grinding
Traditional granite mills
Careful Packaging
Sealed for freshness
Yamamasa Koyamaen exemplifies small-batch artisanal production. Their tea gardens in Uji benefit from generations of soil cultivation and careful plant selection. Traditional shading techniques using natural reed screens allow precise control over leaf development, creating the ideal balance of chlorophyll, amino acids, and flavor compounds. The family personally oversees the spring harvest, selecting only the most tender first-flush leaves. After steaming and drying, leaves are stone-ground in small quantities to maintain freshness and prevent oxidation. This hands-on approach means production is limited, but quality is uncompromising. Each batch is tasted and approved by family members before release, maintaining standards passed down through generations.

Smooth & Creamy
Yamamasa Koyamaen matcha is distinguished by its vibrant jade-green color and exceptional umami richness. The aroma is fresh and vegetal with sweet undertones reminiscent of steamed edamame and fresh-cut grass. On the palate, you'll experience a bright, clean flavor profile with pronounced umami that coats the mouth without heaviness. The natural sweetness emerges mid-palate, balanced by gentle vegetal notes and minimal bitterness. The texture is smooth and creamy when properly whisked, creating a luxurious mouthfeel. The finish is remarkably clean and refreshing, leaving a lingering sweetness that invites another bowl. Their Samidori variety is particularly noted for its balanced character, making it accessible to newcomers while satisfying experienced matcha drinkers.
Optimal Preparation
For best results, use 1.5-2g of matcha with 70-80ml of 175°F (80°C) water. Whisk vigorously in a "W" or "M" motion for 15-20 seconds until a fine foam forms. The quality of Yamamasa Koyamaen matcha produces excellent foam and reveals its full flavor complexity.
