Uemura Masakatsu was a botanist & pharmacologist in the service of Tokugawa Yoshimune.
Uemura managed the medicinal garden at Wakayama when Tokugawa Yoshimune was daimyô there. In 1716, when Yoshimune became shogun, Uemura accompanied him to Edo, planting a larger pharmacological garden in Edo's Komaba neighborhood in 1720. He left that same year on a journey to explore the plants and medicines of the country, a journey which in the end lasted 34 years. In 1740, he compiled a nine-volume account of his travels entitled Shoshu saiyaku-ki, which he submitted to Yoshimune.
