Japanese tea growers eponymously call this tea, NADESHIKO, after its creator, Osada Natsumi Nadeshiko. It is made with a blend of three cultivars and undergoes a patented fermentation process inspired by sake brewing, called the black koji process. NADESHIKO tea is organically grown in Shizuoka, Japan and presents a unique balance between the brightness of green tea and the rich complexity of a black tea, exhibiting notes of raspberry, juniper, and minerality.
Osada-san is bringing the past and future together by joining tradition with modern science. Each batch of tea is carefully fermented in a sterile, temperature-controlled environment to ensure clean, consistent, and health-focused results. It is celebrated in the scientific community for containing two new polyphenols that have been shown to help regulate blood sugar, reduce visceral fat, and support cardiovascular health. Osada Natsumi Nadeshiko is a tea instructor of the 8th dan and has received numerous awards for his pioneering work in microbial fermentation. His signature tea is thoughtfully presented in a generous fold of handmade Japanese washi paper, flecked in gold and silver.
Osada Natsumi Nadeshiko is a fourth-generation tea master and the director of Osada Seicha in Shizuoka, Japan. The craft of growing organic tea is advancing through his pioneering work in microbial fermentation, which has earned him numerous awards, including the 2021 Nihoncha Platinum Award. Osada-san is a certified tea instructor of 8th dan (the highest professional rank), and continues to evolve the future of Japanese tea through innovation rooted in tradition.
