Tea Day, Black Tea Day, and Genmaicha Day are celebrated in Japan every November 1, honoring the country's rich tea culture. Tea Day, or Ocha no hi, commemorates the birthday of Shoichi Kokushi, also known as Enni, a Buddhist monk credited with introducing tea to Shizuoka Prefecture in the 13th century. Black Tea Day, established by the Japan Black Tea Association in 1983, honors Daikokuya Kōdayū, who encountered black tea during his nine years in Russia and is believed to be one of the first Japanese men to drink it. Genmaicha Day celebrates a unique blend of green tea and roasted brown rice, historically known as "people's tea" for its affordability. This day highlights the significance of these teas in Japanese culture, with various organizations promoting their appreciation and consumption.
