Double Driver ‘Kamen Rider W’

I’ll show you how to make a Double Driver, the transformation device from Kamen Rider W, that looks just like the real thing.
Prepare reference photos or illustrations and start tracing the shapes onto cardboard.
Since the cardboard pieces will be layered based on your references, carefully tracing along the photos or illustrations is key to getting the shape and sense of size right.
As you glue layers together, cut out the individual parts, adjust their placement so each piece sits in the correct position, and sandwich in plastic sheets as needed.
For the base components, cut two identical pieces of cardboard and glue them together to increase strength—this is another important point.
Making the belt loops with silver tape may further improve functionality.
Once all the parts are glued together, you’re done.
Mask of Bitter-Gau from Kamen Rider Gauv

Kamen Rider Gauv features a colorful indoor setting that evokes sweets like gummies and candies, beautifully expressing Gauv’s world.
With sweets as its theme, Gauv is a unique work in which the hero equips confections to transform.
Because of this candy theme, it’s a story likely to capture children’s interest.
Here, we’ll introduce the Bitter-Gau mask from Kamen Rider Gauv.
Attach the cut-out template to a board and cut it out.
Carefully finish the edges by sanding them smooth.
Assemble the cut pieces, paint them, and create the eyes to complete the mask.
Children are sure to be delighted by a mask that looks just like the real thing.
Kamen Rider Gav Costume

Children’s dream come true! Here are some ideas for a Kamen Rider GAV costume.
You might think, “Can I really make the same outfit as Kamen Rider?” But with this video as a guide, let’s create a costume kids will love.
What you’ll need includes cushion mats, cosplay board stickers, plastic wrap, fabric adhesive tape, and vinyl cloth.
Since the materials and instructions are available, it’s a great project to take your time with during long breaks.
When using spray paints and the like, be sure to work in a well-ventilated area.
DecaDriver ‘Kamen Rider Decade’

The “Decade Driver,” with its striking card-insertion transformation, becomes even more engaging when you make it together as a parent-child project.
By shaping it from everyday materials and adding clever joints for moving parts, you can even recreate the transformation gimmick.
Incorporating a mechanism to store cards greatly expands the ways to play.
Decorate it using thick paper and containers to give it a substantial, authentic look.
A rider belt you build with your own hands becomes not only a toy to play with but also a piece you can proudly display in your collection.
Kamen Rider Gov Belt
Here’s how to make a handmade transformation belt from the kids’ favorite “Kamen Rider Gav.” Get your materials ready: cardboard, origami paper, felt-tip pens, clear tape, glue, vinyl tape, and scissors.
Cut the cardboard into the shape of a belt.
Apply black vinyl tape, carefully covering the surface so no gaps in the cardboard show.
Using red origami paper, cut out the red sections of the belt while checking the shape, then glue them on.
Draw the face with a felt-tip pen, and you’re done.
If you attach an extra piece of cardboard to the back of the belt that clips into the waistband of pants, it won’t slip down while playing and will stay secure.
Give it a try with your child!
Mask of Kamen Rider Gav – Hopping Mi Form

Popping Migochizou was born when the protagonist, Shoma, ate grape-flavored gummies.
Let’s make the mask for Kamen Rider Hopping-Mi Form, which uses Popping Migochizou to transform.
We’ll use interlocking foam mats.
Transfer the pattern onto the foam mat and cut it out.
Assemble the pieces to create the base mask.
Next, use COS board—often used for cosplay costumes and props—to build the face section.
Attach film to the eyes, add color to the facial parts, and you’re done.
It’s easy to make with everyday materials, so give it a try!
Kamen Rider Geats Mask

Let’s try making the mask of Ace Ukiyo from Kamen Rider Geats, which features a white fox motif.
For the pattern, copy the mask parts onto thick paper and cut them out.
You can find copies online.
When transferring based on the pattern, use a Super Sentai base mask.
Next, trace the pattern onto a board, cut it out, and glue the resulting parts together.
Attach the board parts to the base mask, then paint them white and vermilion to complete the Geats mask.
Since you’re using a base mask, you can make a professional-looking mask.
