A 100-meter-long Koinobori, widely known as carp streamer, weighing more than 300 kilograms, was hoisted by a crane during 'Peace Festival' on Friday in Kazo, Japan, two days before the country’s Children's Day. /VCG Photo

Around 120,000 people came to see the giant carp, which was lifted into twice during the day for 15 minutes each time. /VCG Photo

Instead of fluttering in the wind as usual, colorful carp streamers really ‘swim’ in a river in Yamaguchi Prefecture, western Japan, on Friday to celebrate the upcoming Children’s Day. /VCG Photo

Households across Japan are decorated with carp streamer from April to early May to wish for the health of children. /VCG Photo
