[Childcare] Ocean-themed craft ideas! From wall displays to 3D projects
In summer, ocean-themed crafts are a common activity in childcare.
Ocean motifs feel refreshing and are perfect for the season.
Sea creatures like fish and crabs are fun for children to make.
However, finding age-appropriate ideas and new forms of expression can be challenging.
So, we’ve gathered a collection of ocean-themed craft ideas here.
You’ll find a variety of projects, from flat drawings to three-dimensional creations.
Please use these as a reference and enjoy a fun summer with the children! Note: Since the children’s creations are treated as works, the term “seisaku” (制作) is used in the text.

Tissue paper fish and handprint crab
Let’s make fish and crabs using tissue paper and handprints! For the fish, first cut construction paper into a fish shape, then crumple some tissue paper and glue it on as scales.
Add eyes and other details, and the fish is done! For the crab, paint a child’s open hand with paint and stamp it onto construction paper.
Try stamping so that the thumbs become the eyes and the other fingers become the crab’s legs.
Once it’s dry, add eyes using construction paper or round stickers, and it’s complete! If you cover the artwork with clear plastic, it can look like an aquarium tank.
Give it a try with your kids’ adorable little hands!
Guri and Gura’s Seaside Swim

Let’s try making a craft inspired by the picture book “Guri and Gura’s Seaside Adventure.” First, use blue and white paint on light blue construction paper to create waves.
Prepare the environment so the children can freely express themselves.
Make Guri and Gura using origami—don’t forget their trademark red and blue hats.
Next, cut out two swim rings from construction paper.
Finally, glue all the parts onto the paper, and it’s complete! Just looking at it will make you feel like you’re at the beach.
Crab and Parasol
Let’s make a summer-perfect craft with crab and parasol motifs! A scene where a crab is enjoying a day at the beach is sure to spark children’s imaginations.
First, draw the sea on a sheet of construction paper as the base.
Choose either pastel crayons or paints depending on the children’s age.
Next, create the crab and parasol parts.
If the children can handle scissors well, let them do the cutting.
Prepare decorations for the parasol—such as round stickers or stamping—based on the children’s interests.
Glue all the parts together, and you’re done! You’ll end up with a wall display that almost lets you hear the sound of the waves.
Swimmy
Do you know the story of Swimmy? It’s about a little fish named Swimmy, the only one left after a tragedy, who goes on an adventure across the vast ocean, meets many wonderful friends, and regains his sense of self and energy.
This picture book teaches the importance of friendship, so please try reading it together with children.
If you create while expanding the imagery of the story, the kids will surely come up with lots of ideas.
Use a large wall space to depict a grand ocean, and post many colorful fish that showcase the children’s individuality.
Making one big fish together is a lovely idea that can foster a sense of unity in the class.
snow crab

This is a snow crab, a sea creature characterized by its large claws and unique shape.
Fold the origami into a triangle, then fold back the bottom portion to create additional creases.
Turn it over and continue folding along the creases to form steps; this will create the crab’s body.
To represent the crab’s signature large claws, layer the paper as you fold, sharpening the tips for a realistic finish.
Once you’ve shaped the claws, draw the eyes with a pen at the end to complete a cute snow crab with an expressive look.
