The Gojo River in Iwakura City, Aichi Prefecture, has about 1,400 cherry blossom trees that continue along the river for about 7.5 km. The Iwakura Sakura Festival is held every year during the cherry blossom season. Dashi floats are on display during the festival, and Nonbori Arai is performed in the rivers. During Nonbori Arai carp streamers are placed in the river to wash off the glue used in Koi Nobori (carp streamers) making. On May 5th in Japan, there is a custom of raising a carp streamer at your home for your sons, representing courage and the ability to attain high goals. In Iwakura, there is a long-established shop that makes carp streamers. The Gojo river is a photogenic spot where you can enjoy Japanese traditional culture and cherry blossoms at the same time.
