In Japan, Mother's Day (母の日 Haha no Hi?) was initially commemorated during the Shōwa period as the birthday of Empress Kōjun (mother of Emperor Akihito) on 6 March. This was established in 1931 when the Imperial Women's Union was organized. In 1937, the first meeting of "Praise Mothers" was held on 8 May, and in 1949 Japanese society adopted the second Sunday of May as the official date for Mother's Day in Japan. Currently Mother's Day in Japan is a rather commercial holiday, and people typically give their mothers gifts of flowers such as red carnations and roses.
