Meaning of “捕らぬ狸の皮算用”
“Don’t catch tanuki’s skin calculation” is a proverb that warns against making hasty calculations or plans based on things that haven’t been realized yet or things you haven’t obtained.
This proverb is used when you see someone acting as if they have already succeeded in uncertain matters. For example, it’s used for people who think in detail about how to spend their winnings just from buying a lottery ticket, or those who make detailed life plans for after employment without even receiving a job offer yet.
Even today, this lesson holds very important meaning. In all situations—investments, business plans, life planning—we tend to make calculations based on the assumption of future success. However, reality is not so sweet. This proverb teaches us the danger of making spending plans based on income that hasn’t been confirmed yet, or thinking about the next steps based on uncertain results. In other words, it’s truly practical life wisdom that preaches the importance of steadiness and caution.
Origin and Etymology
“Don’t catch tanuki’s skin calculation” is thought to have originated as an expression rooted in the daily life of common people during the Edo period. Tanuki were animals with high value as fur at that time. Especially tanuki winter fur was prized as cold-weather gear and decorative items, and traded at good prices in the market.
The background to this expression becoming established lies in the experiences of people from an era when hunting was familiar. Calculating the profit from selling the skin before catching the tanuki. Because such scenes were commonly seen in daily life, this proverb was born.
The word “skin calculation” is also an interesting expression. This literally means “calculation when selling the skin,” referring to calculating the value of something you haven’t obtained yet in advance. It’s thought that such expressions naturally arose within the merchant culture of the Edo period.
Actually catching a tanuki was not an easy task. Even if you set traps, they wouldn’t necessarily be caught, and they often escaped. Yet seeing people calculate the price of the skin before catching them, people must have smiled wryly, thinking “they haven’t even caught it yet.” This is how this proverb became established as common people’s wisdom.
Interesting Facts
Tanuki fur was a luxury item worth tens of thousands of yen in current value during the Edo period. Especially winter fur had high density and was treasured as lining for samurai and merchant haori coats, so catching one would have been quite an income for common people.
The expression “skin calculation” was also used for animals other than tanuki. “Rabbit skin calculation” and “fox skin calculation” also existed, but the expression using tanuki became established because tanuki were the most familiar animals that seemed easy to catch but were actually difficult.
Usage Examples
- You just started job hunting and you’re already thinking about promotion plans at your new company—that’s Don’t catch tanuki’s skin calculation
- Looking up wedding venues without even proposing yet is completely Don’t catch tanuki’s skin calculation
Modern Interpretation
In modern society, the warning of “Don’t catch tanuki’s skin calculation” has become even more important. With success stories overflowing on SNS and media, we tend to easily think “I can succeed the same way too.”
This tendency appears particularly prominently in the investment world. After hearing stories of people who made big profits from cryptocurrency, FX, or stock investments, many people think about how to use their profits before even starting to invest. Many people probably also make skin calculations about view counts and advertising revenue while dreaming of success on YouTube or TikTok.
On the other hand, “forward-looking planning” is also valued in modern business environments. Future sales forecasts are essential in business plans and marketing strategies. Here lies a modern contradiction. Planning is necessary, but excessive optimism is dangerous.
As a characteristic of the digital age, the fast speed of information dissemination and the tendency for success stories to be transmitted in beautified form also has an influence. Because get-rich-quick stories and short-term success tales enter our vision daily, we’re in an environment where it’s easy to harbor unrealistic expectations.
What’s important is a sense of balance that maintains realistic perspective while holding hope. Having dreams and acting on uncertain assumptions are completely different things.
When AI Hears This
Daniel Kahneman’s discovery of “planning fallacy” describes a cognitive bias where humans underestimate the time and costs needed for future plans while overestimating potential benefits. This phenomenon aligns remarkably with the Japanese proverb about “counting the raccoon dog’s hide before catching it.”
In Kahneman’s experiments, when students were asked to predict their thesis completion dates, the actual completion was delayed by an average of 22 days beyond their predictions. This operates through exactly the same psychological mechanism as calculating fur prices before catching the raccoon dog. Our brains possess an “optimism bias” that makes us focus on favorable information about uncertain futures while downplaying risks and obstacles.
The reason 90% of modern startups fail also stems from founders underestimating market difficulties while overestimating their chances of success. Similarly, the psychology of lottery ticket buyers follows this pattern—instead of focusing on the 0.00001% winning probability, our brains dedicate resources to imagining the wealthy lifestyle after winning.
The fact that a lesson derived from raccoon dog hunting experiences by Edo period Japanese was proven as a Nobel Prize-level psychological theory 300 years later provides valuable evidence that human cognitive patterns remain unchanged across time.
Lessons for Today
What this proverb teaches us modern people is the importance of “balance between hope and reality.” Having dreams is wonderful, but we must not forget that acting on the assumption of things that aren’t yet confirmed is dangerous.
In modern society, both planning and flexibility are required. Preparation for the future is necessary, but that preparation should be done not on the assumption of “if things go well” but “it’ll be okay even if things don’t go well.”
When you take on challenges too, try thinking not only about the best-case scenario but also about what happens if things don’t go as planned. That’s not being pessimistic, but truly being fully prepared. By acquiring this sense of balance—building up sure steps one by one while continuing to hold big dreams—your life will become richer and more stable. Let’s make skin calculations while keeping our eyes firmly on our feet as we walk forward.
