With united hearts and concerted effort

It’s a four-character idiom that expresses uniting hearts with your companions and joining forces.
It shows not only individual strength but also the importance of supporting and cooperating with one another.
Using it at a sports day or team event—like, “Let’s aim for the goal with kyōshin-ryokuryoku (協心戮力)!”—naturally heightens the sense of giving your all together with your teammates.
The phrase carries the message that even things that are hard to do alone can be overcome if you work with one heart, making it a perfect word of encouragement for situations where a team takes on a challenge.
Indomitable perseverance

It’s a four-character idiom that expresses an attitude of remaining unmoved in the face of hardship and persevering with tenacity.
It’s not just about enduring; you can sense the strength of tackling things with an unwavering will.
If you call out, “Let’s see it through with the spirit of steadfast perseverance!” at a sports day or team event, it helps everyone unite and take on the challenge together.
Even if results don’t come quickly, this phrase reminds us of the importance of sticking with things, gently giving us the push to keep making an effort.
That’s the kind of four-character idiom I felt it was.
recklessly charging ahead

It’s a four-character idiom that instantly brings to mind the image of charging straight ahead without hesitation.
Once you learn its meaning, you see it expresses an attitude of forging toward a goal with full force, undeterred by difficulties or others’ opinions.
Saying “Let’s tackle this with reckless charge (chototsu-moshin)!” at a sports day or team event can really fire everyone up.
Of course, caution has its place, but remembering this phrase makes you feel that taking action first is what matters.
I felt it’s a positive and dependable idiom that propels momentum and a spirit of challenge.
battle-hardened; seasoned (literally: experienced in a hundred battles)

It represents the ability, built through repeated experience, to respond calmly and unfazed in any situation.
Just hearing it inspires reliability and composure, which is its appeal.
If you say, “Let’s take this on with a battle-hardened spirit” at a sports day or team event, you can share with your teammates the mindset of acting with faith in the results of your past effort and practice.
It’s a phrase that reminds us of the importance of turning the experiences of overcoming failures and hardships into strength, encouraging ourselves and our teammates to keep challenging—such is the four-character idiom, in my view.
to lie on firewood and taste gall (an idiom meaning to endure hardship and persevere for future revenge or success)

Just hearing it strongly conveys determination and resolve.
It means persevering through hardships and pain, and continuing to strive to achieve your goals.
Even in everyday life, when you face difficult tasks or challenges, remembering it can help you stay positive by thinking, “This experience isn’t for nothing.” If you use it at a sports day or team event—like, “Let’s see it through to the end with a spirit of gashin-shōtan”—it naturally boosts your teammates’ morale.
It teaches the importance of overcoming difficulties and gently supports the strength to keep making efforts and taking on challenges.
That’s the kind of four-character idiom I felt it was.
