Common Japanese expressions

In the following section, you’ll find a collection of Japanese expressions presented in kanji, kana, and romaji—each accompanied by its literal translation and a concise explanation of its meaning in English.

1. 腹八分に医者いらず (はらはちぶにいしゃいらず, Hara hachi bunme ni ishairazu) – Eight-tenths full keeps the doctor away

This Japanese phrase emphasizes the ideal fullness after a meal—about eighty percent of one’s stomach capacity. Often used by mothers, it serves as a gentle reminder to children about the importance of moderation and avoiding overindulgence.

2. 朝飯前 (あさめしまえ, Asameshi mae) – Before breakfast

The phrase “asameshi mae” refers to tasks that are so simple or quick that they can be completed before you even sit down for breakfast. Its English counterpart would be “a piece of cake!”—a way to express just how easy something is.

3. ごまめの歯ぎしり (ごまめのはぎしり, Gomame no hagi shiri) – Little fish grinding their teeth

The phrase “little fish grinding their teeth” conveys a sense of harmlessness, symbolizing that certain actions are minor or unlikely to lead to substantial results. It highlights how seemingly small efforts often lack the power to create meaningful change.

4. 猿も木から落ちる (さるもきからおちる, Sarumo kikara ochiru) – Even monkeys fall out of trees

This Japanese phrase serves as a comforting reminder to friends and family after they experience a setback, conveying a sentiment similar to “Everyone makes mistakes” in English. It’s a gentle way to acknowledge that errors are a natural part of life.

5. 知らぬが仏 (しらぬがほとけ, Shiranuga hotoke) – Not knowing is Buddha

This reference to Buddha reflects a fascinating aspect of Japanese culture: the notion that remaining unaware can sometimes be preferable. This sentiment echoes the English saying, “Ignorance is bliss,” highlighting how not knowing can shield us from discomfort.

6. 明日は明日の風が吹く (あしたは あしたのかぜがふく, Ashita wa ashita no kaze ga fuku) – Tomorrow’s winds will blow tomorrow

While its literal translation may seem redundant or resigned in English, this proverb is intended to inspire hope. It serves as a reminder that each new day brings fresh opportunities and possibilities.

7. 花より団子 (はなよりだんご, Hana yori dango) – Dumplings over flowers

Echoing the principle of “substance over form,” this insightful Japanese idiom emphasizes the importance of prioritizing practical and useful things over mere enjoyment or pleasure. It encourages a focus on what truly matters in life.

8. 明日を語ると天井のネズミが笑う – Speak of Tomorrow and the Ceiling Rats Will Laugh

This saying, resembling a proverb more than an idiom, beautifully expresses the idea that the future is inherently unpredictable. A simpler way to convey this sentiment in English is, “You never know what the future holds.”

9. 相変わらず (あいかわらず, Ai kawarazu) – The same as ever, as always

This Japanese phrase carries a somewhat negative undertone, suggesting that things are just as they typically are. It’s important to avoid using it in positive contexts, as it may undermine your intended message.

10. The Frog in the Well: Ignorance of the Vast Ocean

This Japanese expression parallels the English phrase “a big fish in a small pond,” which describes someone who holds significance within a small community but is largely unknown beyond it. However, the Japanese saying adds a nuanced twist: it highlights individuals who are not only self-important but also judgmental, viewing the world solely through their narrow perspective and remaining oblivious to diverse ideas and lifestyles.

11. 馬鹿は死ななきゃ治らない (ばかはしななきゃなおらない, Baka wa shinanakya naoranai) – Only death can cure a fool

This witty saying highlights the notion that ignorance is an incurable condition; thus, the only way for someone to stop acting foolishly is to no longer be around!

12. 起死回生 (きしかいせい, Kishi kai sei) – Wake from death and turn to life

Embodying the spirit of resurrection, this Japanese proverb inspires listeners to believe in the possibility of transforming even the direst circumstances. It conveys a message that is more vivid than the English saying “turn lemons into lemonade,” emphasizing hope and the potential for positive change.

13. 雨降って地固まる (あめふってじかたまる, Amefuttedjikatamaru) – After rain falls, the ground hardens

At first glance, this saying may appear discouraging, but it actually conveys a powerful message: challenges and hardships catalyze personal growth and transformation. This concept mirrors the English adage, “What doesn’t kill you makes you stronger,” highlighting how adversity can ultimately lead to resilience and strength.

14. 月とすっぽん (つきとすっぽん, Tsuki to suppon) – The moon and a soft-shell turtle

Japanese speakers will often use this expression to contrast choices or things in which one option is obviously superior.

15. 出る杭は打たれる (でるくいはうたれる, Deru kui wa uta reru) – The nail that sticks up will be hammered down

Among the most widely translated Japanese proverbs, this saying emphasizes the belief that pursuing individualism may not always be the ideal path. It reflects the deep-rooted Japanese cultural principle of collectivism, highlighting the importance of community and togetherness over solo endeavors.

16. 案ずるより産むが易し (あんずるよりうむがやすし, Anzuru yori umuga yasushi) – Giving birth to a baby is easier than worrying about it

While it may not resonate with everyone, this Japanese proverb highlights a powerful truth: the anxiety or fear we feel about a situation can often be more distressing than the situation itself.

17. 見ぬが花 (みぬがはな, Minuga Hana) – Not seeing is a flower

Beyond the straightforward phrase “Ignorance is bliss,” this saying suggests that our dreams and fantasies can often appear far more beautiful than the truth we face. In essence, our imagination can create a captivating world that may not align with reality.

18. 砂を噛むよう (すなをかむよう, Su na o kamu yō) – Like chewing on sand

As its tactile imagery suggests, this Japanese expression may be employed when describing something tedious, boring, or dull. 

19. 鯛も一人はうまからず (たいもひとりはうまからず, Tai mo hitori wa umakarazu) – Eaten alone, even sea bream loses its flavor

This Japanese saying emphasizes the joy of sharing meals with loved ones, highlighting that dining alone diminishes the experience. While it’s not identical to the English phrase “the more, the merrier,” it conveys a similar idea: companionship enhances enjoyment.

20. 窓際族 (まどぎわぞく, Mado giwa zo ku) – The window tribe

This phrase describes individuals who avoid meaningful work, often engaging in unproductive activities like gazing out the window. It highlights a specific aspect of Japanese business culture, particularly concerning older employees who, due to social norms and systemic barriers, cannot be dismissed from their positions.

21. 水商売 (みずしょうばい, Mizu shou bai) – water business

Be cautious not to confuse this expression with its literal meaning. In Japanese, this idiom doesn’t describe a business that sells bottled water; instead, it refers to a company characterized by high fluidity or uncertainty.

22. 偽客 (さくら, Sakura) – Cherry blossom

The term “Withkanji,” which translates to “false customer,” describes an intriguing strategy where individuals are employed as decoys. Their role is to gather valuable insights into a competitor’s business operations and market strategies.

23. 一期一会 (いちごいちえ, Ichigo ichi e) – One opportunity, one encounter

Much like the clichéd English phrase “once in a lifetime opportunity,” this Japanese saying emphasizes the uniqueness of each moment. It serves as a reminder to embrace the present and make the most of every day.

24. 七転び八起き (ななころびやおき, Nana koro biyaoki) – Fall seven times, stand up eight

This inspiring Japanese saying serves as a powerful reminder of your inner strength. It highlights that your true identity isn’t shaped by your failures; instead, it’s determined by how you choose to respond to them. Embrace resilience and let setbacks fuel your growth!

25. 雨が降ろうと、槍が降ろうと (あめが ふろうと、やりがふろうと, amega furouto、yarigafurouto) – Even if it rains, or if spears fall

This phrase serves as the Japanese counterpart to the English expressions “no matter what happens” or the traditional saying, “Come hell or high water.” So, whether it’s pouring rain or unexpected challenges arise, this guide is your go-to resource for mastering Japanese idioms!

Japanese idioms that exist in English

You might be surprised to learn that, despite their significant linguistic differences, Japanese and English have a number of common idioms. If you’re eager to expand your understanding of English expressions, be sure to explore the extensive collection of blog posts on idioms at LingualNeeds!

1. 猫に小判 (ねこにこばん, Neko ni koban) – Like gold coins to a cat

While the Japanese expression has a bit less contrast than its English equivalent, “like casting pearls before swine,” it effectively conveys the same message: the folly of offering something valuable to those who cannot recognize its worth. Both phrases illustrate the frustration of sharing precious resources with those who fail to appreciate their true beauty.

2. 弱肉強食 (じゃくにく きょしょく, Jakuniku kyōshoku) – Survival of the fittest

This Japanese expression closely mirrors its English counterpart, conveying a powerful idea: only those who can adapt to their surroundings will succeed.

3. Embrace Risk: No Gain Without Entering the Tiger’s Cave

This saying highlights the crucial connection between taking risks and reaping rewards. In English, we often express this idea with phrases like “No risk, no reward” or “Nothing ventured, nothing gained.” Embracing challenges can lead to greater opportunities and benefits in life.

4. 猫も杓子も (ねこもしゃくしも, Neko mo shaku shimo) – Even cats and rice ladles

Simply put, this cute expression means “everyone” and is the Japanese equivalent of “Everybody and their mother.”

5. 十人十色 (じゅうにんといろ, juunintoiro) – Ten people, ten colors

This brief four-character phrase is not only a fun way to practice your numbers but also embodies a meaningful concept. The simplest English translation of this Japanese expression is the four-word saying: “To each his own.”

6. 口が滑る (くちがすべる, Kuchi ga suberu) – A slip of the mouth

While this Japanese phrase may resemble the English expression “a slip of the tongue,” which generally refers to an accidental remark, it more closely aligns with the phrases “let the cat out of the bag” or “spill the beans.” All these expressions convey the idea of unintentionally revealing a secret.

7. 寿司詰め (すしづめ, Sushi dzume) – Packed like sushi

A fascinating example of the cultural differences between Japan and the West can be seen in a Japanese expression that perfectly mirrors the English phrase “packed like sardines.” Both expressions convey the idea of being in a very crowded space.

8. 因果応報 (いんがおおほう, Inga ō hō) – Bad causes, bad results

This saying embodies the concept of karma, suggesting that negative or dishonest actions will ultimately lead to consequences. In English, it’s often phrased as, “What goes around comes around.”

9. 自業自得 (じごうじとく, Jigō jitoku) – One’s act, one’s profit

Like the earlier saying, this Japanese idiom emphasizes personal responsibility, conveying the idea that “you reap what you sow.” It highlights how our actions directly influence the outcomes we experience.

10. 見ぬが花 (みぬがはな, Minugahana) – Ignorance is bliss

Similar to its English equivalent, this Japanese proverb conveys the idea that sometimes it’s easier to stay oblivious to certain details than to be overwhelmed by excessive information.

11. 一石二鳥 (いっせきにちょう, Isseki ni chō) – One stone, two birds

This four-character expression captures the essence of the English proverb, “to kill two birds with one stone,” meaning to efficiently accomplish multiple tasks simultaneously.

12. 地獄に仏 (じごくにほとけ, Jigoku ni hotoke) – My Buddha in hell

Drawing a striking parallel between Japanese and European history, the phrase “my Buddha in Hell” serves as Japan’s version of the Western “knight in shining armor.” It symbolizes an individual who emerges as a beacon of hope and support during tumultuous times, embodying the essence of a savior when challenges abound.

13. 一日一歩 (いちにちいっぽ, Ichi ni Chī ppo) – One day, one step

Mastering Japanese is a journey that requires patience and perseverance, but this expression can serve as a motivational mantra during tough times. Interestingly, it also doubles as a farewell in Japanese culture. Much like the English phrase “One step at a time,” it evokes the idea of progressing steadily towards your goals.
