Adult pretend fighting

Many of you probably remember playing “pretend battles” when you were in elementary school.
As we grow older, we hardly get chances to play like that, but trying it with other adults once in a while can be a lot of fun.
By using safe equipment—like foam swords or squeaky toy hammers—you can really get into it without risking injury.
Attaching something like a paper balloon as a hit marker to the head makes it easy to tell when someone’s been struck.
Sinking Game

The “Sinking Game” is a fun game that lets you experience the thrill of “the ship might sink!” In a large space like a hall or gym, place several mats randomly.
These mats are the ships, so divide the children into groups and have them stand on the mats.
The teacher plays the role of a scary shark living in the sea.
When the shark-teacher shouts, “We’re sinking!” the children must get off their current mat-ship and move to a different mat-ship.
If they’re caught by the shark-teacher while moving, they’re out! If they can reach another mat-ship without being caught, they’re safe.
Try mixing in other words that start with “chi” instead of “chinbotsu da” to keep the game interesting!
Ball-carrying relay

This is a game where you use a ball balanced on a ladle instead of a baton and try to finish faster than the other team.
It tests not only running speed but also posture and steady form so the ball doesn’t fall off the ladle.
Passing the ball to the next person is also important—matching the height of the ladles and consciously stepping toward each other are key points for winning.
Adding variations that make it easier to lose balance—such as receiving the ball while standing up from a seated position or running a course while avoiding obstacles—heightens concentration and makes the competition even more exciting.
Stack and boom!

This is “Stack and Whack!”: everyone piles their palms up in a random stack; someone yanks their hand out and snaps a flick (shippe) at the stack.
The person who gets flicked removes their hand, and the last person remaining wins.
Didn’t you play this as a time-killer when you were a kid, when you had nothing to do? The idea is to take that and play it seriously.
If you miss and whiff, take a penalty and lower one hand.
Finger tutting

Let me introduce “finger tutting,” a dance that expresses beats and rhythms through movements of the fingers and hands.
The appeal is that you don’t need any props—you can do it with just your hands.
Paired with trendy music, it feels current; with nostalgic tunes, it creates a sense of unity across generations.
It also helps train concentration and finger flexibility, so you can expect brain-training benefits.
Though simple, it has real depth, making it a pastime that adults can get hooked on, and it’s growing popular for parties and recreational events.
By changing the tempo or synchronizing movements with a partner, you can broaden the ways to play.
