Invisible Invaders

This content discusses whether, in a situation where a virus is spreading, families should gather and stay at home or go to work to make a living.
The focus is on how to address the contradiction that prioritizing safety reduces income, while attending school or working in offices increases the risk of infection.
Each member has different positions and opinions—such as the desire to protect children and the elderly and the sense of responsibility to support the economy—leading to a clash of values.
Through speaking, participants not only express their own views but also develop the ability to understand others’ thinking.
If the discussion is held in class, it becomes a deeply educational theme that allows students to simulate the challenges faced by society as a whole.
Territory game! S-Ken

A game called “S-Ken,” where teams compete to steal a treasure from territories drawn in a large S-shape.
Participants split into two teams and start from their respective sides.
Decide roles in advance: who will defend your territory and who will steal the enemy’s treasure.
When the start signal is given, move by hopping on one foot from outside the S to the enemy’s territory.
Once you enter the enemy’s area, you can move with both feet, so quickly grab the treasure.
The square spaces near the enemy territory are safe zones where you can stand on both feet and rest.
Those in your own territory should push enemies out of your area and protect the treasure.
The treasure can be anything like a stone on the ground.
An apartment building where only teachers live
Set in an apartment building inhabited only by teachers, this theme has you deducing who lives in which room.
Using 14 hint cards as clues, players share information to piece together the overall solution, making cooperation essential.
It’s crucial to decide how to share the cards in your hand and how to organize information from others’ statements.
Through conversation, both logical thinking and teamwork are tested, and the whole class gets excited.
As the deduction progresses, there are moments of discovery, and the sense of achievement when you reach the conclusion is exceptional.
It’s a theme that lets you enjoy the fun of cooperation and deduction.
Six patients and medicine

It presents the ultimate choice: help one critically ill patient or save five moderately ill patients.
There is only one dose of medicine; the critical patient needs the entire dose, whereas the moderate patients can all survive if it is divided among them.
The dilemma of valuing a single life versus prioritizing the many exposes one’s values.
Key discussion points include whether all lives are equal in weight or whether social roles should be considered.
It is important for the whole class to debate and work toward a single final decision, making this a thought-provoking theme that lets students experience the challenges of ethics and difficult choices.
Escape from the Desert

This is a consensus game with the scenario: your plane has made an emergency landing in a desert where only cacti grow.
You have 12 items, such as a flashlight, a compass, a plastic rain poncho, and an aerial photo map.
Rank these items in order of importance.
First, think individually, then discuss within your group.
Consider detailed conditions—like temperatures exceeding 40°C and the nearest settlement being over 100 km away—as you work toward the optimal solution.
No equipment needed! Air catch ball

“Air Catch,” a make-believe game of tossing an imaginary ball without any props, is a very simple team-building activity.
Participants form a circle.
Someone calls another person’s name while miming a throw of the “air ball,” and the next person pretends to catch it and continues in the same way.
The rules are: make eye contact and call the person’s name before you throw.
Once everyone gets used to it, you can increase the difficulty by tossing multiple balls at once or speeding things up.
It builds communication skills and concentration and gets people laughing, making it great for training icebreakers and strengthening team cohesion.
It takes about 5–15 minutes, so give it a try!

Compliment game

After all, to boost teamwork it’s important to recognize one another.
As a game that can spark that mutual recognition, the “Praise-Praise Game” is highly recommended.
The rules are very simple: you just take turns complimenting each other’s good points.
Both giving and receiving compliments can feel a bit embarrassing, but it’s a great way to discover your own strengths, so definitely give it a try.
Escape Game

How about a mystery-solving escape game that puts your team’s unity to the test? It’s well-known as an event at a certain theme park, too.
In this game, each team member needs to tackle the puzzles, share their opinions, and arrive at a single conclusion in order to escape.
The difficulty is high, but if you succeed, everyone can share the sense of achievement.
It’s a recommended game for those who want to boost teamwork.
Commonality-Finding Game

Let’s try finding things we have in common.
Even with someone you don’t know, discovering common ground brings you closer and helps you hit it off and keep the conversation flowing.
Of course, similarities in appearance count, but talking about things like whether you have siblings or pets can also improve your communication skills.
You could even add a time limit, like “Find X things in common within X minutes.”
Conversation Experiment Game

When you’re talking with someone, being ignored or having them look away while they listen feels completely different from being listened to with smiles and encouraging nods, doesn’t it? Conversation experiment games are important to re-confirm this obvious truth.
By actually trying this out as a team, I believe the team’s bonds will grow even stronger.
