Four-character idioms (1–10)
Once-in-a-lifetime encounter
Ichigo ichie, meaning a once-in-a-lifetime encounter.
A school festival may be something you can experience once a year while you’re in school, but every single thing that happens on that day is actually a once-in-a-lifetime moment.
The food selling out at a booth, the joyful voices of visitors, clashing with your teammates—each may seem like something you could experience again and again, but your feelings are different every time, so in truth, each is its own ichigo ichie.
With the determination to work hard to witness those wonderful sights you can only encounter at a school festival, and only in that place, how about choosing this phrase?
To each their own.
Having teammates with diverse personalities come together to create an event is an essential element in making a school festival exciting.
A phrase that highlights both collaboration with such teammates and each person’s individuality might be “juunin toiro” (literally, “ten people, ten colors”).
It’s a saying that brings back various memories, including the fact that a group of people with different ways of thinking can sometimes clash.
It also conveys the powerful energy that emerges when personalities that usually face in different directions start moving toward the same goal.
unity; standing together as one

To make a big event like a school festival a success, isn’t it important for everyone to move forward with a unified spirit? This is a simple four-character idiom that seems to express cooperation with companions and moving in the same direction.
By clearly putting into words the idea of working together to create the event, it creates a moving sense that diverse personalities are advancing toward the same goal.
Precisely because these words feel so natural, they serve as a reminder of our bonds and the direction we’re headed.
Single-minded focus spanning a vast distance
Through school festivals, students across the school and within the same class can feel solidarity and a sense of achievement as they work toward a single goal.
This seems to be one of the purposes of holding a school festival.
How about the slogan “Banri Ikkū” for the festival, which conveys the idea of continuing to strive toward one objective? “Banri Ikkū” is said to express the mental state Miyamoto Musashi reached after years of training.
Of course, enjoying the school festival is important, but so is uniting as a class and preparing together toward one goal.
It is also essential to cooperate, for each person to fulfill their role, and to keep making efforts.
“Banri Ikkū” is a four-character idiom that encapsulates the key values of a school festival.
A hundred flowers in full bloom
The visual appeal of a slogan matters too.
With that in mind, I’d like to introduce the four-character idiom “百花繚乱” (hyakka ryōran).
It originally describes a beautiful scene where a great variety of flowers are in full bloom.
By extension, it’s also used to depict a gathering of people with diverse talents.
Using this idiom as a slogan can convey the message that your class is filled with many different kinds of talent.
It can also be adopted as a phrase that emphasizes respect for each individual’s uniqueness.
