意思
Things appearing one after another in rapid succession.
文化背景
Bamboo shoots are a quintessential spring food in Japan. The act of 'Takenoko-hori' (bamboo shoot digging) is a popular seasonal activity. This deep familiarity with the plant makes the idiom very relatable to Japanese people. The idiom is shared across China, Korea, and Japan, reflecting a shared 'Sinitic' cultural sphere where bamboo was a primary resource for construction, paper, and food. In modern Japan, this phrase is most frequently seen in tech journalism to describe 'copycat' startups or the rapid adoption of global trends like QR code payments. In traditional Japanese gardens, bamboo is carefully managed because it spreads so fast. The idiom also carries a hidden nuance of 'hard to control' because of this speed.
Use with 'のように'
90% of the time, this phrase is followed by 'のように' (no you ni). Memorize it as a single block: '{雨後|うご}の{筍|たけのこ}のように'.
Not for literal rain
If you are actually talking about gardening after a storm, just say '{雨|あめ}が{降|ふ}って{筍|たけのこ}が{出|で}た'. Using the idiom might sound like you're making a joke.
