QShould "Koinobori" carp-shaped streamers be displayed on Tango no Sekku?

AIt is always pleasant to see carp streamers fluttering under the clear blue sky and swaying in the spring breeze. “Koinobori” is the most representative decoration for the “Tango no Sekku” festival, and it symbolizes wishes for the boy's vigorous growth and success in life. Please be as positive as the circumstances of the surrounding environment in which you wish to display it allow.
