Meaning of “雨後の筍”
“After rain bamboo shoots” is a proverb that describes how similar things appear one after another in succession, just like bamboo shoots that emerge from the soil all at once after rainfall.
This expression originated from observing how bamboo shoots grow vigorously after rain and emerge simultaneously from various parts of a bamboo grove. It specifically refers to situations where similar phenomena or events occur concentrated within a short period. It is used in contexts such as a rush of new store openings, the release of similar products, the occurrence of similar incidents, or the emergence of newcomers – whenever things of the same tendency appear in rapid succession.
The reason this expression is used is because the characteristics of bamboo shoot growth overlap with people’s actual experiences. When conditions are right, bamboo shoots grow rapidly all at once, and they have the nature of emerging not just individually but one after another from the surrounding area. This overlaps with the “chain reaction phenomena” seen in human society, allowing for accurate expression of situations. Even in modern times, this natural phenomenon metaphor remains relevant in various contexts such as the spread of trends and market movements.
Origin and Etymology
“After rain bamboo shoots” is a proverb that originates from Chinese classics. Bamboo shoots have long been known as plants that emerge from the soil all at once after rainfall and grow at a surprising speed.
This expression is believed to have been transmitted to Japan through Chinese classical literature and Buddhist scriptures. Zen Buddhist texts in particular contain numerous metaphorical expressions using natural phenomena, and “After rain bamboo shoots” appears to have been used in such contexts.
Bamboo is a familiar plant throughout East Asia, and its rapid growth was a phenomenal occurrence for people. The growth of bamboo shoots, which can extend several dozen centimeters overnight, was indeed the perfect symbol for phenomena that “increase in number in the blink of an eye.”
In Japan, it began appearing in literature around the Heian period and became widely used among common people during the Edo period. For people of that time, the sight of bamboo shoots emerging all at once in bamboo groves after rain was truly the representative example of things “appearing one after another.” The fact that this proverb has continued to be beloved for so long can be said to be a manifestation of the wisdom of our ancestors who skillfully incorporated natural phenomena into words.
Interesting Facts
Bamboo shoots can actually grow up to 120 centimeters in the 24 hours following rain, which is among the fastest growth rates in the plant kingdom. This extraordinary growth power supports the persuasiveness of the proverb.
Also, the Chinese character for bamboo shoot “筍” combines “竹” (bamboo) and “旬” (season/period), meaning “seasonal bamboo” or “bamboo that grows in a short period.” The concept of “rapid change in a short period” is embedded in the character itself.
Usage Examples
- Recently, cafes have been opening one after another like After rain bamboo shoots in this area
- Online meeting tools appeared like After rain bamboo shoots during the COVID pandemic
Modern Interpretation
In modern society, “After rain bamboo shoots” demonstrates its power particularly when expressing the rapid changes of the digital age. The emergence of smartphone apps, the rise of YouTubers, the proliferation of cryptocurrencies – phenomena where new services and professions are born one after another alongside technological progress are truly like After rain bamboo shoots.
With the spread of social media, the phenomenon where similar content is mass-produced instantly when one trend emerges can also be accurately expressed with this proverb. TikTok dance challenges and Instagram posting trends – the behavioral patterns of the digital native generation are reminiscent of bamboo shoot growth speed.
On the other hand, modern views toward “After rain bamboo shoots” phenomena have become complex. Among things that increase rapidly, low-quality items tend to be included, and “appearing like After rain bamboo shoots” is not always used in a positive sense. Changes in values that emphasize quality over quantity in our information-overloaded era are also influential.
Nevertheless, the image of “natural growth and spread” that this proverb possesses continues to function as a very effective metaphor for understanding modern viral phenomena and the rapid growth of startup companies.
When AI Hears This
In the proverb “bamboo shoots after rain,” the “rain” functions not merely as background scenery, but as a decisive catalyst triggering phenomena. The bamboo shoots already existed underground, but with the addition of rain as an external condition, they all emerge on the surface simultaneously. This structure aligns remarkably with the mechanisms behind social phenomena.
For instance, when personal streaming apps sprouted like bamboo shoots after rain following smartphone proliferation, the “rain” was the technological innovation of smartphones themselves. When online meeting tools rapidly multiplied during the COVID pandemic, the “rain” was the social change of lockdown restrictions. What’s crucial is that these services and ideas likely existed beforehand, but specific conditional changes caused them to surface all at once.
This can also be explained through psychology’s “threshold theory.” Human behavioral change has certain thresholds, and when stimuli (rain) exceeding these thresholds are applied, latent behaviors manifest simultaneously. Just as bamboo shoots prepare for growth underground, society constantly accumulates “something in preparation,” which explosively appears the moment appropriate conditions align.
In essence, “bamboo shoots after rain” represents not a superficial phenomenon of multiple occurrences, but an inevitable result of interaction between latent elements and catalytic conditions—making it an extremely scientific metaphor.
Lessons for Today
What “After rain bamboo shoots” teaches modern people is the importance of discerning waves of change. Various trends and phenomena appear one after another in the world, but it’s important to have the eye to distinguish what is truly valuable among them.
Just as bamboo shoots grow by receiving the condition of rain, we too receive the “rain” of changing times and gain opportunities to challenge new things. What’s important is not just going with the flow, but finding our own way of growing.
This proverb also teaches us the importance of “timing.” Bamboo shoots only grow when appropriate conditions are met at the appropriate time. We too should acquire the wisdom to wait for our time without rushing and act when the time is ripe.
In modern society, information and opportunities appear like After rain bamboo shoots, but we don’t need to jump at all of them. The power to select what is truly necessary for us, what leads to growth, may be the most important teaching this proverb gives to modern people.
