Taki Handa was a Japanese horticulturist, best known for designing and directing the construction of a Japanese garden in Scotland in 1908. Handa was born in Kurume, Kyushu. She studied Chinese literature, weaving, and English as a girl, and was baptised as a Christian at age 16, then trained to be a teacher at a school in Fukuoka. She attended Studley College in England from 1906 to 1908.
Handa designed a seven-acre garden at Cowden Castle in Clackmannanshire for Ella Christie, who had travelled extensively in Asia and wanted to recreate the Japanese garden aesthetic. Handa returned to Japan and taught botany, horticulture and English at Doshisha Women's College in Kyoto.
