Rose Day (Rōzu no Hi)

What is Rose Day?

June 2nd is "Rose Day." According to the Japan Anniversary Association, it was established by the Bulgarian Rose Culture Association, a general incorporated association based in Yokohama, Kanagawa Prefecture (some sources instead name French Lace, a general goods store in Kashiba, Nara Prefecture). The date is a wordplay (goroawase): 6 and 2 can be read as "rō-zu," the Japanese pronunciation of "rose," and it also falls in the season when roses bloom beautifully. In Bulgaria, famous for its roses, a festival celebrating the rose harvest is held in early June; the day aims to spread that culture in Japan and wishes for a warm, peaceful world where people gather around roses. June is also when roses are at their best in many parts of Japan, making the day an occasion to turn our attention to roses as both a plant and a cultural symbol.

The history of rose breeding

Roses have been bred and improved over a very long period. From the 19th century onward, crossbreeding that incorporated traits such as the repeat blooming of Chinese roses advanced, and garden roses with a vast array of colors and forms became widely popular.

• Today, roses are grown as ornamental plants worldwide

Japan's relationship with roses

Japan has its own wild roses, such as noibara (Rosa multiflora), hamanasu (Rosa rugosa), and teriha-noibara (Rosa luciae), and the Man'yōshū poetry anthology of the Nara period includes "umara," thought to refer to noibara. These Japanese wild species were used as parents in breeding cluster-flowered and climbing roses, contributing to the development of Western garden roses. Western garden roses spread widely in Japan from the Meiji period onward and became beloved fixtures in parks and gardens.

• Wild roses have grown in Japan since ancient times
