Until recently, I never knew that bamboo had flowers.

When Oomiya Takezai Kougei — one of the bamboo artisans we work with — mentioned it in passing during a conversation last year, I had to stop and ask them to explain. What they described is one of the strangest and most beautiful phenomena in the plant kingdom: bamboo blooming.

It happens only once every 100 to 120 years. And it's happening now, across Japan.

What Actually Happens

Bamboo spends its entire life — decades, sometimes over a century — growing without any sign of flowering. Then, in a single synchronized event, an entire species or grove will suddenly bloom. All at once. No exceptions.

After the flowers appear, the bamboo uses every remaining resource to produce seeds. Then it dies. The whole grove, gone.

New bamboo will eventually grow from those seeds, but it takes years — sometimes many years — for the forest to recover. Scientists still don't fully understand why bamboo evolved this way. The leading theory is that mass flowering is a survival strategy: flooding the forest floor with seeds overwhelms predators, ensuring that at least some survive to germinate.

But the result, for those watching, is striking. Groves that were lush and green are slowly turning yellow and falling still.

What It Means for Bamboo Craftsmanship

Bamboo is not incidental to Japanese craft — it's foundational. Rice paddles, zaru colanders, baskets, trays, screens — the list of everyday tools made from bamboo runs through centuries of domestic life.

Artisans like Oomiya Takezai Kougei have spent decades working with bamboo, developing the particular knowledge of how it bends, splits, dries, and ages. When a grove dies, they can't simply switch suppliers. The species, the age, the region, the harvest timing — all of it matters. It may be years before new bamboo is mature enough to work with.

There's something quietly moving about this. The tools they make have always carried the story of the material. Now, pieces made from this generation of bamboo carry something more: the story of a once-in-a-century ending, and the beginning that follows it.

Bamboo and Impermanence

In Japanese culture, bamboo has long symbolized resilience and flexibility — qualities it genuinely has. But this blooming event suggests something else too: that even the most enduring things move in cycles we can't always see.

The Japanese word mono no aware (物の哀れ) describes a gentle melancholy at the transience of things — an awareness that beauty is partly made beautiful by the fact that it doesn't last. Watching a grove of bamboo die in full bloom feels like that. Strange and sad and somehow right.

The last time this happened was 120 years ago. Nobody alive today witnessed it. In another 120 years, the people who see it now will be gone too.

That's a lot to hold for a plant most of us walk past without a second thought.

Have you seen bamboo blooming, or read about it happening near you? I'd love to hear in the comments.
