Hiroshima Flower Festival is held annually in early May in Hiroshima. There is a grand parade and the display of various flowers and art works decorated with flowers. Multiple stages are set up along Heiwa-Odori Boulevard, where singing and dancing performances can be watched. Besides, Koinobori, the carp streamers, are hanged everywhere to celebrate Boys’ Day. 

Atomic Bomb Dome and Hiroshima Peace Memorial Park are visit-worthy to learn the dreadful history of war. Also, in the good climate, cycling along Shimanami Kaido is joyful to see the charming scenery of Seto Inland Sea.
