Hiroshima Flower Festival in Hiroshima
The Hiroshima Flower Festival began in 1977, inspired by the celebratory parade held after the Hiroshima Toyo Carp's first league championship in 1975. Held each May 3-5 along Peace Boulevard near Hiroshima Peace Memorial Park, its Grand Flower Parade features roughly 8,000 costumed participants, drawing more than 1.6 million visitors to one of Japan's largest annual civic parades.
The Hiroshima Flower Festival traces its unlikely origin to professional baseball rather than any older civic or religious tradition: after the Hiroshima Toyo Carp won their first-ever Central League championship in 1975, the city staged a celebratory parade honoring the team, and the enthusiastic public response to that event inspired organizers to transform the concept into a recurring annual festival beginning in 1977.
