Koinobori of Kashiwa Mochi
Let’s make a Kashiwa-mochi carp streamer using kashiwa mochi, which is eaten during the Boys’ Festival (Tango no Sekku).
Cut construction paper into a leaf shape, draw the veins with a white crayon, and paint over it with green paint to create a wax-resist effect.
Cut another piece of construction paper into the shape of a carp streamer and draw patterns with crayons inspired by kashiwa mochi.
Place the leaf on top and glue them together.
Attach a face and a samurai helmet folded from origami, then stick them onto the carp streamer to finish.
It also sounds fun to choose parts of the project according to the child’s age and ability!
Koinobori and Kintaro
We’ll introduce a craft activity featuring carp streamers (koinobori) and Kintaro.
Prepare a paper plate, ribbon, a photo of the child, and koinobori cutouts.
Cut out the center of the paper plate to make a wreath base.
Use finger stamping on the koinobori to create the scales.
Place the child’s photo in the center and add a Kintaro headpiece on top.
Attach the koinobori as well, and you’re done! We recommend using paper plates with printed patterns.
This is a craft that even 0-year-olds can enjoy, so give it a try.
Carp streamers swaying in the wind
@hanamikoto8 Makes me want to swim on the wind 🎏#KoinoboriOrigamiHow to makeChildren's Daywall surface#Production VideoKoinobori (carp streamers)#100-yen-shop

Let me introduce carp streamers that sway gently in the wind.
Prepare washi-pattern origami paper, felt-tip pens, paper, scissors, and tape, and let’s get started.
Fold the origami paper about a quarter of the way and draw the eye.
Use tape to join both ends and form the paper into a tube-shaped carp streamer.
Make cuts at the end, fold the pieces inward to shape the tail fin, then do the same on the opposite side to finish the carp streamer.
When connecting them, attach thin strips of paper to both ends and link the streamers together.
The sight of the carp streamers swimming as they sway in the wind is truly lovely.
Color-changing Koinobori
@yopiko148 I tried making a pattern-changing carp streamer, kind of like a sequin T-shirt ♡#HandmadeToysKoinobori CraftingTranslation#Secret message

When you stroke the scales with your hand—like magic!—the colors change.
Here’s an idea for a carp streamer (koinobori) that I’d like to share.
It’s a unique concept I recommend for anyone unsure how to make their koinobori.
You’ll need construction paper, vivid-colored round stickers, and pastel-colored round stickers.
In recent children’s clothing, you often see designs where stroking sequin illustrations with your hand changes the pattern, right? Using that idea, you can make a koinobori that’s fun to create and fun to play with.
Hanging carp streamers

Be soothed by the gently swaying decorations! Here are some ideas for a hanging carp streamer (koinobori).
How about making a cute koinobori using familiar materials? Cut construction paper into a carp streamer shape, apply glue, then crumple torn pieces of tissue paper and stick them on.
Finish by coloring it with paint diluted in water, and your koinobori is done.
Attach the parts with twine to turn it into a hanging koinobori decoration.
Give it a try!
Koinobori made with paper chains

A vibrant interior accent! Here are ideas for making carp streamers using paper chains.
Displaying ready-made carp streamers is nice, but how about turning the making process itself into a memory? Creating them together—from children to adults—can deepen bonds as you communicate through conversation.
Try making colorful and dynamic carp streamers with origami paper, construction paper, and paper tape.
Once you finish, you’re sure to feel a sense of accomplishment.
Colorful Unit Koinobori

Let’s connect triangular parts and make it! Here’s an idea for a colorful unit-style carp streamer.
When you think of Children’s Day, many of you probably picture koinobori, right? This time, let’s make a koinobori using colorful origami! What you’ll need: eight pieces of origami cut to 7.5 cm, and a strip of white origami cut to 15 cm by 3 cm.
Although the finished piece looks complicated, the charm of this idea is that it can be made with simple steps!
