Spice Up Setsubun! A Collection of DIY Oni (Demon) Pants Ideas (11–20)
Translation
When it comes to oni cosplay, a mischievous image is the norm.
You picture a rowdy look that seems ready for pranks.
That lively style is great, but how about surprising everyone with a gentlemanly oni instead? Try a coordinated set of oni-print pants with a matching bow tie and rock your Setsubun event in style.
The pattern and colors can be the classic yellow base with black stripes, or any color variation you like.
Make a bow tie from the same fabric and pair it with a white shirt, and you’ve got a refined, gentlemanly oni formal look.
Stand out with oni cosplay that’s a little different from everyone else’s.
loop yarn
Loop yarn has become a common sight lately in women’s knits and the like.
Those who work in apparel will be very familiar with this fabric.
It’s a bit hard to describe in words, but it’s a material with a unique fluffy texture made up of lots of tiny, curly loops of yarn.
If you do a quick search, seeing is believing—you’ll go, “Oh, that fabric!” How about making oni pants with that loop yarn? The fabric somehow evokes an oni’s hair, so it adds fantastic flair to cute outfits.
It would look great for matching parent-and-child looks too!
raincoat
On rainy days at concert venues, to keep from getting soaked on theme park log flume rides, and so on—you’ve probably been buying inexpensive raincoats more often lately.
But there aren’t many chances to use those raincoats again, right? So let’s repurpose unwanted raincoats to make an oni’s pants! That distinctive swishy feel also matches the fun of bean-throwing, I think.
If the raincoat is transparent, just line the inside with yellow felt and you’re good to go!
white + brown
Bold, eye-catching oni pants in yellow and black are great, but a calm palette like white and brown also looks stylish—highly recommended! Especially for knitting, you often use white and brown yarn, so it’s nice and easy to gather materials.
With this combo, adding a touch of gold yarn would give it an even more glamorous finish.
The design pairs well with off-white and beige clothing, so it’s a good choice for an adult Setsubun costume too.
The colors aren’t too flashy, so it will look chic when you post photos on social media!
Lum-chan

Lum-chan is an adorable character who adds “-daccha” to the end of her sentences.
She’s a horned heroine from the TV anime Urusei Yatsura, which aired until 1986.
For those in their 40s and 50s, she’s a nostalgic icon—so why not bring her back for today’s Setsubun celebrations? With store-bought horn accessories, it should be easy to recreate Lum-chan.
Urusei Yatsura was remade as an anime in 2022, so riding the wave of its renewed popularity, it might be fun for not only kids but also adults to try making a Lum-chan costume!
