Meaning of “柳の下の泥鰌”

“Loach under willow” means that it is foolish to expect success again in the same place or using the same method just because you succeeded once before.

This proverb warns against the foolishness of people who mistake accidental success for ability and try to repeat the same thing. When initial success was due to chance or luck, the same conditions may not align again. Since situations are constantly changing, being too attached to past successful experiences can lead to misjudging reality.

This proverb is often used particularly in business, investment, and human relationships. For example, it’s used in situations where continuing to make products similar to one that happened to sell well doesn’t guarantee success. It teaches us that there’s no point in superficial imitation without properly analyzing the factors behind success.

Origin and Etymology

The origin of “Loach under willow” is thought to have emerged from the daily life experiences of common people during the Edo period. People of that time would sometimes catch loaches under willow trees by the riverside. The base of willow trees was where water tended to stagnate, making it an easy place for loaches to hide.

Even if someone happened to catch a loach under a willow tree, returning to the same place wouldn’t necessarily guarantee finding loaches there again. Loaches are mobile creatures and also have the habit of avoiding places where they were once caught. In other words, the initial success was a product of chance, and expecting the same results using the same method is unrealistic.

This proverb is said to have appeared in literature from the mid-Edo period onward and is thought to have spread as a lesson based on common people’s actual experiences. People of that time lived in close contact with nature, so they carefully observed animal behavior and natural phenomena. The wisdom born from such keen observation is embedded in this proverb.

Also, using the familiar creature of loach makes it an expression that anyone can easily understand, which is characteristic of this saying.

Interesting Facts

Loaches are actually very sensitive creatures with the habit of not approaching places where they’ve been startled once. They’re also sensitive to changes in water temperature and quality, rarely staying in the same place for long.

For people of the Edo period, loaches were a valuable source of protein, but catching them required considerable skill and experience. Therefore, “accidentally catching one” was probably a familiar and easily understood example for people of that time.

Usage Examples

  • Just because you drew a winning lottery ticket at that store once doesn’t mean going back will work – that’s like expecting a loach under willow
  • Just because the last presentation went well by chance doesn’t mean reusing the same materials – that’s like aiming for a loach under willow

Modern Interpretation

In modern society, the meaning of this proverb may have become even more important. Particularly in the world of social media and the internet, there’s a phenomenon called “going viral,” but even if something becomes a topic of conversation once, repeating similar posts rarely generates the same response.

In the business world too, there was a time when “benchmarking” – directly copying past success stories – was popular, but in today’s world where market environments and consumer needs change rapidly, superficial imitation alone no longer works. Rather, the ability to analyze the essential factors of success and adapt them to current situations is required.

The same applies to the investment world, where being too attached to stocks or methods that generated profits in the past can lead to losses by failing to keep up with market changes. The basic investment principle that “past performance does not guarantee future results” can be said to be the modern version of this proverb.

On the other hand, in modern times, analyzing success patterns and creating reproducible systems is also valued. The effort to turn accidental success into inevitable success might be what true ability is all about.

When AI Hears This

Modern business management requires vast amounts of time and data to scientifically analyze “the reproducibility of success,” yet people in the Edo period perfectly articulated this complex concept simply by observing a creature called the loach.

The fact that loaches are found under willows is actually not coincidental. Willow roots extend into the water, attracting small fish and insects, creating an ideal feeding ground for loaches. In other words, there are clear “success factors” at work. However, on the surface, all we see is the result: “a loach was found under a willow.”

This perfectly matches modern business failure patterns. Many companies that fail while trying to imitate successful enterprises only copy the visible elements (store appearance, product lineup, etc.) while overlooking the invisible success factors (location conditions, customer base, timing, etc.).

What’s remarkable is the sense shown by Edo period people in choosing the humble loach. If they had chosen a flashy fish, people might think “it was just lucky,” but with a loach, it makes you think “there must be some reason.” Through this exquisite choice of creature, they perfectly expressed 400 years ago the core principle of modern management theory: that reproducing success requires not superficial imitation, but essential factor analysis.

Lessons for Today

What this proverb teaches modern people is the importance of discerning the essence of success and failure. Rather than getting intoxicated by a single success, it’s important to develop the habit of calmly analyzing why we succeeded.

In modern society, information overflows and many success stories are introduced. However, superficial imitation alone is meaningless. Only by understanding the effort, environment, timing, and other factors behind that success can we build our own version of success.

Also, rather than clinging to past successes out of excessive fear of failure, we need the courage to continue taking on new challenges. Precisely because we live in an era of rapid change, flexibility and adaptability are required.

This proverb teaches us humility and a realistic perspective. Being grateful for luck and chance while not depending on them – having that kind of strength. Such an attitude is what leads to true growth, don’t you think?
