[Mini Sports Day] Carefully selected indoor-friendly events that really get everyone excited!

Ball pool treasure hunt

[Treasure Hunt] Secure the loot in a ball pit where making any noise is absolutely forbidden!

Ball pits are hugely popular with children, especially little ones.

Even adults watching from the sidelines might feel tempted to jump in because it looks so fun! Let’s try an indoor game using a ball pit: a treasure hunt in the ball pit! There are surely places like preschools where kids regularly play in ball pits, or facilities that have a ball pit but aren’t making the most of it.

Try mixing in items that are a similar size or color to the colorful balls—things that are a bit harder to spot.

Even children who get a little nervous at events like sports days might enjoy this as a playful, low-pressure activity.

Bubble Ball Sumo

[Sports Festival] Sumo with bubble balls was insanely fun! Use power and technique to push your opponent out!

Bubble Ball Sumo adapts the rules of traditional sumo while players wear bubble balls on their upper bodies and body-check each other.

Beyond its funny appearance, it becomes a deceptively deep contest thanks to the strategy of how far to push and when to dodge.

It can be run safely even in limited indoor spaces, and laying down mats on the floor makes it even safer and more enjoyable.

Momentum and timing often decide the outcome, leading to surprising upsets that are a major highlight.

Organizing head-to-head matches in a tournament format amps up the cheering and can strengthen class unity.

Win or lose, everyone ends up smiling—this is a hard-hitting performance that can be the centerpiece of any event.

True-or-False Quiz

Answer true/false quiz questions; the last person remaining in the correct area wins! Before the game starts, set up a True (O) area and a False (X) area.

Participants move to the area they believe is correct; if they’re right, they stay in and advance to the next question.

Since knowledge, intuition, or luck matter more than physical strength, it’s a great chance for those who aren’t confident in sports to shine.

Parachute Performance “Que Sera Sera” at the 49th Sports Day, Hana Class

Parachute play using a large, colorful cloth.

Several people hold the cloth and inflate it to create moves like a dome, carousel, and fireworks.

To raise and lower the cloth or move it sideways, it’s essential for the whole team to synchronize their breathing.

To help everyone keep time, it can also be useful for a leader to give cues with a whistle.

Ippon-bashi Rock-Paper-Scissors

[Bonbon Academy] We tried a boys-vs-girls balance beam rock-paper-scissors showdown!

A competition where two teams start from opposite ends of a balance beam, and the first to cross wins while playing rock-paper-scissors along the way.

The rules are simple: the winner of each rock-paper-scissors round advances, while the loser steps off the beam and returns to the starting point.

Many people probably played a similar game in parks as children.

Since crossing the balance beam itself requires good balance, you might fall before even facing your opponent, which adds fun beyond just speed.

It’s a great event for indoor sports days that both participants and spectators can enjoy together.

Fruits Basket

[Ages 3–4] “Fruit Basket”

Fruit Basket is a game that almost everyone likely experienced as a recreational activity in childhood.

You prepare a number of chairs that is one fewer than the number of participants, and the “it” stands in the middle.

The basic rules are: participants are divided into groups by fruit in advance, and when the “it” calls out a fruit, the people assigned to that fruit must get up and find a different chair from the one they were sitting in.

At the same time, the “it” also searches for a chair, so the person left without a seat becomes the next “it.” There are also local rules, such as everyone having to stand when the “it” calls “Fruit Basket,” or not being allowed to sit in the chair immediately next to you.

Thanks to these, the role of “it” doesn’t get too lopsided, making it a fun game for everyone.
