From a kiting perspective, these brightly colored shimmering tubes are closer to being windsocks. However, since these are such a major part of Japanese kite culture I thought they still deserved a page on this site.
lightweight, open at one end and closed at the other is pretty close

available online, some sets of these "kites" are very glossy and
vibrantly colorful. The color can fade after a while, but it all depends
on how you treat them and how long they spend in the sun!
Near the bottom of this page is a great image plus a link to some others that have been carefully collated.
these colorful decorations have not caught on in a big way here in
South Australia, since I have not spotted any at the annual kite
festival. Traditional rokkakus yes, on one occasion, but no "fish
kites" have made an appearance!
It used to be for boys only, but Japan has moved with the times so that both boys and girls can enjoy the day now.
On this day, fish kites and streamers are hung from bamboo poles outside people's homes, representing the male occupants. In fact, this goes for poles everywhere around the country and even from the occasional car aerial! As the wind blows into the mouth of the windsock, the kite wriggles around giving the impression of a fish swimming upstream.
The great photo below shows some pristine and very glossy-looking Japanese fish kites, err sorry, carp windsocks. The traditional colors of red and blue are also present, on the far right.
