In 1478, hundreds of ume were planted to celebrate the renowned scholar Sugawara no Michizane, who liked plum trees. The name "Bairinzaka" means Plum-Grove Hill in Japanese. Today, only about 50 trees remain between Bairinzaka and Honmaru. The earliest blooms start in December, and the trees reach full bloom in mid-February.
