Marlborough Anniversary Day began in 1859 with the creation of Marlborough Province after its separation from Nelson. Even though the provinces were abolished in 1876, the holiday survived as a regional anniversary day. It continues as a symbol of regional identity and pride, as well as a springtime holiday for residents.

Culture Day promotes the arts, culture, and academic achievement, encouraging appreciation for creativity and peace. The date marks the anniversary of Japan’s postwar constitution proclamation in 1946. Events include art exhibitions, parades, school performances and award ceremonies, such as the Order of Culture, presented by the Emperor to honor outstanding contributions to Japanese culture and society.
