killing two birds with one stone
They say, “If you take a walk in the park, you can refresh your mind and make up for a lack of exercise—truly killing two birds with one stone.” This means that by walking in the park and moving your body, you’ll both lift your spirits and address insufficient exercise.
It’s a four-character idiom used to express gaining two benefits or results from a single action.
When using the idiom ‘ikkyō ryōtoku’ (killing two birds with one stone), clearly explaining what action you take and what benefits or results you gain will make your point more persuasive and easier for others to understand.
Once-in-a-lifetime encounter
The four-character idiom “ichigo ichie” carries the meaning of cherishing the special, once-in-a-lifetime moment at hand, and is rooted in the teachings of the tea master Sen no Rikyū.
Through the words of Rikyū’s disciple Yamanoue Sōji, the phrase spread in the Edo period when the tea master Ii Naosuke recorded it as “ichigo ichie” in his collection Tea Gatherings: Once-in-a-Lifetime Meetings.
“Ichigo” means “a lifetime,” and “ichie” means “a single tea gathering.” It’s a beautiful saying that encourages both the host and the guests of a tea gathering to approach the occasion with wholehearted sincerity, as if it were a once-in-a-lifetime moment.
friendly rivalry; mutual improvement through competition
He says, “I’ve been able to grow this far by spurring each other on with my cohort at the company.” This means that because there was someone who joined the company at the same time as he did, he worked hard with the determination not to lose to him—both as a rival and as a teammate—and they grew by pushing each other to improve.
The term “sessatakuma” refers to mutually encouraging and competing with one another to improve in work, study, and as human beings.
It’s a four-character idiom used for relationships within a group or team where people positively stimulate each other and boost motivation.
a hard-fought struggle
“Akusen-kutou” refers to struggling through a very difficult battle and making every effort to overcome it.
In sports matches or games where there’s a winner and a loser, you sometimes find yourself on the verge of defeat.
But you can’t win if you give up there.
Remember the word “akusen-kutou” and hang in there.
By doing so, you might just turn the situation around.
The strength to never give up, no matter the circumstances, will surely become a great source of power for you.
Wind, Forest, Fire, Mountain
People say, “His life is like Fūrinkazan.” This sentence means that he responds flexibly to various situations and takes bold action as needed.
“Fūrinkazan” is a famous four-character idiom written on the war banner of the warlord Takeda Shingen.
When using the idiom “Fūrinkazan,” it’s clearer to the listener if you explain specifically how each element—wind, forest, fire, and mountain—maps to actions, behaviors, or states.
The highest goodness is like water.

It is a saying that means “The highest good is like water.” Just as water changes its shape to fit the vessel, it teaches the importance of living gently and flexibly.
Water, without asserting itself forcefully, has the power to wear down stone little by little.
And like water flowing from high to low, it also conveys a natural, unpretentious way of being.
Someone who cherishes their own thoughts while being attuned to the feelings of others may have a “heart like water.” Even when facing difficulties, they don’t become rigid, but move forward positively, adapting to the situation.
That attitude can be said to lead to true strength.
Limit Break

When you’re working hard at something and hit a wall, you become aware of your limits, don’t you? If you can’t break through with your current ability, the only option is to take a bigger leap and challenge it again.
That’s what it means to surpass your limits.
Put simply, it’s about not setting a finish line for your own strength and aiming to become even stronger and cooler! If you like games, you might think of it as leveling up.
All of you elementary school students are still growing and full of potential.
When you hit a wall, think of it as a chance and bring out your abilities and charm to the fullest!
A land of picturesque mountains and clear waters

It’s read as “sanshi suimei.” The on-yomi (Sino-Japanese reading) of the character for purple includes “shi,” which makes it a bit tough for elementary schoolers.
It means the mountains are purple and the waters are clear, describing scenery of exceptional beauty.
It’s a bit curious that mountains can look purple when the sun shines on them.
This expression was coined by the Edo-period Confucian scholar Rai Sanyō.
It’s said he was deeply moved by the view he could see from his home in Kyoto and created the term.
Use it in sentences like, “On our school trip, we encountered many scenes of sanshi suimei.”
matchmaker (literally: “go-between under the moon,” meaning a person who brings two people together, especially for marriage)

A person who acts as a go-between for a man and a woman is described as a “gekkahyoujin” (matchmaker).
This term combines “Gekka Rōjin” (the Old Man under the Moon) and “Hyōjin” (the Ice Person).
Both come from classical anecdotes.
“Gekka Rōjin” refers to a Tang-dynasty tale in which a man named Wei Gu hears from a mysterious old man about a red cord—what we now know as the red thread of fate.
“Hyōjin” comes from a story in which Linghu Ce of the Jin dynasty had a dream interpreted about speaking with someone beneath the ice, which was taken to mean he would serve as an intermediary for marriage.
Flower in the mirror, moon on the water

This is a four-character idiom that means “beautiful things that you can see but cannot grasp.” For example, a flower reflected in glass, clouds in the sky mirrored in a puddle, or the moon reflected on a bathroom window at night are all very beautiful, yet you can’t touch them.
Likewise, the dazzling lights at an amusement park, or the feeling when you can’t yet buy a toy you really want, can be described as kyōka suigetsu—“things that are fun to look at but can’t be obtained.” It’s a phrase you can use to describe everyday moments that feel dreamy and a little mysterious.
