Dekapan Race: A fun event using dekapan (oversized pants)
As the name suggests, “dekapan” are oversized pants, and they’re often used in sports day events.
Two people each put a leg through, and then take part in various contests like relays.
In this article, we’ll introduce a variety of sports day activities that use dekapan.
Even classic events like relays, obstacle races, and giant ball rolling become uniquely fun when you add dekapan into the mix.
The dekapan themselves can even serve as a substitute baton in a relay! Be sure to try using dekapan and enjoy all sorts of events.

Dekapan Race: Fun Competitions Using Dekapan (1–10)
Parent and child big-pants race

The big-pants race is also perfect for when you want to participate together with parents or guardians.
You and a parent both get into the oversized pants and run while holding hands.
Since you have to match your stride and pace, it might be a chance to reaffirm the strength of your bond.
Sharing the same big pants also highlights the difference in body size, making the child look especially cute.
It’s heartwarming for spectators, too, and snapping photos will make for great memories.
While it’s a competition to see who can run the fastest, be sure to enjoy those aspects as well.
In boxers! The Olympic torch relay

A perfect event to kick off the sports day is the “Giant-Pants Torch Relay.” Before the Olympics begin, there’s always a torch relay, right? This event is modeled after that.
Participants get into oversized pants and pass a baton representing the Olympic flame in a relay.
Unlike a regular relay, the fun twist is using an extra-large baton.
It also adds to the excitement because it feels “just like a torch relay.” You can make it even more fun by crafting the torch and the flame as separate pieces and having participants run while balancing the flame on top.
Big underpants rolling a giant ball

We also recommend combining a giant ball roll, which is fun for cooperating with teammates, with a two-person “dekapan” race.
There are several rule sets for giant ball rolling, but here we’ll introduce one based on the version where multiple people roll the ball.
Think of it like replacing a relay baton with a giant ball: two people in the shared oversized “dekapan” pants push the ball and relay it to the next players.
In a standard giant ball roll, players push from the sides, making it easier to go straight.
In this version, however, two people push from the front, so it requires even better balance.
[Giant-Pants Race] Fun events using giant pants (11–20)
Three-legged race in oversized pants
How about trying a “giant-pants three-legged race,” which combines oversized pants with a three-legged race? The method is simple: two people each step into one leg of the oversized pants, tie together the adjacent legs, and move forward like a three-legged race.
Since you can’t move ahead without syncing your steps, you’ll naturally call out to each other and cooperate, which should strengthen team bonds.
Your teamwork will be tested not only when moving forward but also when getting back up after a fall.
Pairing people with similar stride length and foot speed is the key to victory! Give it a try.
Marshmallow-eating big-pants race
If you want to add a unique twist to the oversized-pants race, we recommend the Marshmallow-Eating Oversized-Pants Race! Teams of two advance while wearing giant pants, find marshmallows hidden in flour without using their hands, and race to the finish line.
Teamwork matters, of course, but the key is how quickly you can ditch your shyness and find the marshmallows in the flour! Just imagining two people with flour-covered faces desperately running in oversized pants is hilarious.
This event is guaranteed to get everyone excited—be sure to give it a try!
Backward-facing big pants race
If you’re looking for a more challenging “dekapan” race, this is a must-try! How about racing while facing backward? Dekapan races are hard enough when walking normally unless you’re perfectly in sync, and adding the rule of going backward could make for nonstop laughter.
You might veer off in unexpected directions or nearly take a tumble—great fun for spectators, too.
The key to winning is to move slowly and steadily while paying close attention to each other’s movements and calling out cues.
This event is sure to fill the venue with smiles, so give it a try!
Blindfolded big-pants relay
If you want to add extra thrills and excitement to the Giant Pants Race, this one’s for you! Introducing the Blindfolded Giant Pants Race.
Here’s how it works: of the two people wearing the giant pants, one is blindfolded while the other guides them, and they move forward together in this high-adrenaline style.
The key to the event is the trust between the guide, who stays calm and gives clear directions, and the blindfolded partner, who believes those words and takes one step at a time.
Spectators won’t be able to look away—it’s bound to lead to hilarious moments! It’s a memorable event that naturally creates laughter and bonds.
Give it a try!
In conclusion
We introduced various games using the giant pants—what did you think? There were many ways to arrange them, like adding obstacles or going shopping with the giant pants.
You can buy giant pants at online shops, and if you need a large quantity, you can also rent them.
You can even make your own with items like plastic bags, so feel free to look into it if you’re interested.
