A flagpole with self-tinkered Japanese wind cones in carp shape (Koi-Nobori). At the children's festival two large carps are suspended for the parents and small ones for the children.
The carp streamer emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the activities
category. Because the carp streamer emoji has been around for quite some time, it should display correctly in the majority of operating systems.
