Is your team struggling to stay connected? Traditional “happy hours” often fail to bridge the gap between diverse roles and personalities. If you are looking for a high-impact experience that fosters psychological safety and inclusive collaboration, it is time to look at the Japanese concept of Undokai (Field Day).
In Japan, Undokai is a time-honored cultural event designed to build unity. At IKUSA, we have modernized this tradition into a professional team-building solution. These activities are designed to be “unbalanced,” meaning physical athleticism isn’t the deciding factor—coordination and strategy are the keys to winning.
Whether your goal is to sharpen the PDCA cycle, identify hidden leadership, or simply reward your staff, here are 41 curated activities to transform your organizational culture.

These activities are designed to break the ice and encourage teams to adapt to unconventional challenges together.
・Ladle Balance Relay This activity requires 10 to 20 participants to balance speed with precision. Each runner carries a ping-pong ball in a ladle, acting as a baton, and must navigate a set course to a turnaround point. Because the ball is exceptionally light, the team must focus on steady coordination rather than raw speed to ensure a seamless handoff.
・Dizzy Bat Dash Injecting energy into any event, this race challenges 10 to 20 people to test their equilibrium. Each player spins around a bat ten times at the starting line before attempting to run a straight line toward their teammates. It serves as an excellent equalizer, as physical fitness matters far less than the ability to laugh through disorientation.
・The Flower Pedestal This is a high-density coordination challenge for groups of 10 to 20. Teams compete to see how many members can simultaneously stand on a small, elevated platform. Success depends entirely on physical cooperation and creative positioning, forcing the group to find a collective balance.
・True or False Quiz To reinforce organizational knowledge, 10 to 20 participants move between “O” (True) and “X” (False) zones marked on the floor. As an MC poses questions about company history or industry trends, those in the wrong zone are eliminated, making it a fun way to align the team around corporate values.

Participants must strictly follow a rhythmic stepping pattern—three steps forward and two back—to reach the finish line. Any deviation from the pattern requires a restart, emphasizing the need for disciplined execution.

・Stick Pull In a high-energy scramble for 20 to 30 people, multiple sticks are placed in the center of the field. Teams must decide which sticks to prioritize and how to allocate their “manpower” to pull the most items back to their base.
