@hakatacraftcola0701 Today's theme is "lightning speed."Translationtranslationtranslation#artworks#shortsvideoVideoTranslationImage#CraftColaFukuoka
♬ Original Song – Hakata Craft Cola – Hakata Craft Cola
It is a four-character idiom that describes extremely swift action and the briefness of such a moment, like a flash of lightning or the spark from flint.
The phrase comes from the fact that both a lightning flash and a flint spark are lights that vanish in an instant, and it also conveys the awe unique to natural phenomena.
If you understand how quick the originating phenomena are, you can clearly picture the speed expressed by this idiom.
It’s a term used to convey admiration when witnessing rapid movement, and it carries a sense of respect for transcendent ability.
Single-minded pursuit of truth
It’s a four-character idiom that conveys a straightforward mindset and attitude—believing only in the truth and seeing it through.
Yamamoto Yuzo’s novel “Shinjitsu Ichiro” (The Road of Truth) is also well known, and in that work the phrase appears as a key word expressing the characters’ stance.
The term not only communicates a will to advance toward the truth, but also evokes a pure heart that refuses to deceive itself and strives to live with integrity.
In the sense of staying true to one’s convictions, the word also clearly carries a sense of strength.
a match for a thousand
@hakatacraftcola0701 Today's theme is "one warrior worth a thousand."translationTranslationImage#shortsvideo#artworksTranslationTranslationVideo#CraftCola
♬ Original Song – Hakata Craft Cola – Hakata Craft Cola
This four-character idiom expresses that a single mounted warrior is so strong he can take on a thousand enemies—someone possessing such exceptional ability.
Its prototype is the phrase “ichinin tōsen” (one person equal to a thousand) found in Chinese classics and Buddhist texts.
Adapted to fit Japanese samurai culture, it spread after appearing in the Taiheiki as “these are all soldiers who, each on one horse, are worth a thousand.” While it strongly evokes fighters, especially samurai who battle with strength, it’s also used more broadly to describe outstanding talent.
It’s often used with a sense of respect when witnessing someone’s abilities firsthand.
Single-minded focus spanning a vast distance

♬ Escort – MoppySound
This is a four-character idiom that expresses the attitude of continuing to strive without losing sight of a single goal, even over a long journey.
“Banri” refers to a vast distance, and “ikkū” means a single sky, so it is also used in the sense that the world is connected.
The fact that it originates from Miyamoto Musashi’s The Book of Five Rings is another key point, and you can feel the persuasiveness precisely because these are the words of a swordsman remembered through the ages.
With the bright imagery of the sky, it gives the impression that the hardship of sustained effort is expressed in a positive light.
lion-like heroic effort; dauntless, furious valor (acting with extraordinary vigor)
@hakatacraftcola0701 Today's theme is 'a lion's furious struggle' (shishi-funjin).#artworkstranslationImageTranslationtranslation#shortsvideo
♬ Original Song – Hakata Craft Cola – Hakata Craft Cola
This four-character idiom describes doing things with fierce, tremendous force, like the king of beasts—the lion—rousing itself with vigor.
It originates from Mahayana Buddhist sutras such as the Lotus Sutra and the Great Perfection of Wisdom Sutra, where it portrays how the Buddha, through passionate and dynamic preaching and action, overwhelmed his audience and non-Buddhists.
By likening it to an animal, it clearly conveys a powerful and courageous figure.
It is used to praise someone’s achievements or efforts, expressing respect.
power over life and death
@hiroaki946 Seisatsu-yodatsu (Power over Life and Death) Shorts Short video Mini video Idiom Four-character idiom Proverb Japanese Language Meaning Wordplay Learning Education Trivia Japanese culture Time-killer Study Knowledge Trivia Everyday life Power of words VOICEVOX: Shikoku Metan A four-character idiom that was often heard about a year ago: “Seisatsu-yodatsu” Example sentence: In a certain country, with a single command from the king, some reached the peak of glory, while others lost their lives. This is what it means to hold the power over life and death. Meaning: “Seisatsu-yodatsu” means having someone else’s life and fate in your own hands. “Sei” is “to let live,” “satsu” is “to kill,” “yo” is “to give,” and “datsu” is “to take away.” In other words, it describes a state where whether others live or die, or whether their property is given or taken, all depends on one’s will. This four-character idiom is used to emphasize having absolute power or control. That is all.
Original song – hiroaki946 – hiroaki946
This four-character idiom expresses having complete control: the power to keep someone alive or kill them, to grant things or rights or take them away—everything can be done at one’s discretion.
By pairing kill with life and take with give, it conveys that the choice between the two is entirely up to the person in control.
Because it describes a disadvantageous situation of being controlled, it is also used as a lesson advising not to leave such power to others.
Since it appears in the ancient Chinese work Xunzi, it is a saying that has long been passed down together with its moral lesson.
Blue sky beyond the clouds
@az0202za # Beyond the clouds, the sky is blue # Believe in “beyond the clouds, the sky is blue” and never give up # Four-character idiom
♬ Original Song – 0202civo – az0202za
This four-character idiom conveys hope that beyond overcoming difficulties lies a bright future and good things, inspired by the idea that blue skies spread beyond the clouds.
It is said to originate from a poem by the Chinese literatus Xie Fangde, “The crane pierces the clouds and ascends into the blue sky,” and has been passed down since ancient times.
It is the perfect phrase for moments when you face hardship and feel like giving up, giving you the courage to take a step toward hope.
By envisioning the blue sky beyond the clouds through this saying, it feels like you can face anything with a positive mindset.
monsters and spirits; malevolent specters (chimimōryō)
@kurukoba Four-character idioms; four-character compounds; demons and monsters (chimimōryō)
♬ Original Song – Bird v🔍💙 – Hour of Four Ripe
A four-character idiom that serves as a collective term for various monsters and yokai, used to express something terrifying.
“Chimi” refers to monsters born from the vital energy of mountains and forests that harm people, while “moryo” are said to arise from the vital energy of rivers, mountains, trees, and stones; together they evoke beings beyond human understanding.
Because of its association with monstrous creatures, the term is also used to describe people who scheme for selfish gain or those who are as inscrutable as monsters.
Even the number of strokes in the characters conveys a sense of dread alongside a certain power.
Actions speak louder than words.
This four-character idiom expresses an attitude of quietly and steadfastly doing what needs to be done without resorting to words or theories.
Instead of speaking at length, it emphasizes demonstrating value and results through action, conveying a taciturn impression.
It suggests that words are unnecessary to achieve outcomes; one simply forges ahead with stubborn determination.
It’s a powerful phrase that embodies a spirit of facing challenges head-on and is said to have inspired the idea behind “say and do” (yūgen jikkō), the principle of fulfilling what one declares.
battle-hardened; seasoned (literally: experienced in a hundred battles)
This four-character idiom describes a state where one’s martial skills, technical abilities, and mind and body have been thoroughly honed through many battles and experiences.
The key point is that it’s used precisely because of repeated, real-world practice, and it evokes the image of someone with gravitas.
For example, a soldier or warrior might be called “a seasoned veteran,” while in business one might say “a battle-hardened/seasoned executive,” pairing the idiom with the specific field of experience.
It’s a term that conveys respect for strength—the strength to fight in one’s respective arena by leveraging hard-won experience.
