Bamboo Shoot in Osawa Village

Phyllostachys edulis

Bamboo, native to tropical and temperate regions worldwide, was introduced to Japan centuries ago and historically provided significant social, cultural, and ecological benefits. For centures, it has been deeply integrated into everyday life in Japan. It serves as a material for household items such as kitchen utensils, tableware, and brooms, traditional crafts such as fans, lanterns, and umbrellas, and construction materials including drainpipes and components of earthen walls. In addition, its extensive root system has been valued for stabilizing slopes and reducing the risk of landslides caused by heavy rainfall and earthquakes.

Despite these benefits, bamboo is one of the most aggressive invasive plants. Through its underground rhizome network, new shoots of Phyllostachys edulis can emerge several yards from the parent plant, allowing bamboo groves to expand rapidly. Today, this expansion is driven not only by the plant’s biology but also by the decline of Satoyama, the Japanese tradition of human-managed landscapes surrounding villages. As these landscapes are abandoned due to rural depopulation, aging communities, and urban development, bamboo is no longer managed effectively and spreads into forests, farmland, and residential areas. Climate change has further contributed to its expansion by allowing bamboo to survive in regions that were once too cold.

My painting was inspired by Osawa Village, one of the few places in Tokyo where a traditional Satoyama landscape is still carefully maintained. Residents continue to harvest bamboo shoots each spring. Bamboo shoots symbolize healthy growth and future potential, and have been traditionally enjoyed for Children’s Day celebrations on May 5. Today, however, they can no longer be harvested for the celebration because they emerge almost a month earlier than they once did and remain edible for only a few days.

Rather than depicting only the bamboo shoot above ground, I wanted to reveal the hidden structure beneath the soil. The underground rhizome is as fascinating as the towering culm above it. It spreads horizontally through the soil, producing new shoots, branches, and roots from regularly spaced nodes. A young bamboo shoot first curves slightly toward the rhizome before turning upward, protected by tough, bristly culm sheaths marked with diffuse brown blotches. At its base, the shoot develops thick, succulent roots, while the rhizome itself produces a network of thinner, fibrous roots. Both remain close to the soil surface, supporting the bamboo’s remarkable ability to spread.

One of the most extraordinary features of bamboo is its rapid growth. Much of the shoot’s structure is already formed before it emerges from the ground, allowing it to elongate with astonishing speed. Under favorable conditions, Phyllostachys edulis can grow nearly three feet in a single day, making it one of the fastest growing plants in the world.

When I planned to visit Osawa Village, no bamboo shoots had yet appeared. After two nights of heavy rain, however, the forest floor suddenly came alive with emerging shoots. I was fortunate to be guided by an experienced local resident who could detect buried shoots simply by feeling the ground beneath his feet. He carefully dug out a young shoot that was still attached to its rhizome and then worked patiently to free it without damaging the underground structure. Thanks to his remarkable effort, I was able to observe a hidden part of the plant that is rarely seen.

The freshly unearthed shoot was strikingly beautiful. As I followed the plant from the rhizome to the emerging culm, my appreciation was deepened for the remarkable biology of bamboo and the cultural landscape that has shaped its relationship with people for centuries. Through this painting, I hope people will look beyond the familiar image of bamboo and discover the hidden connections beneath the soil. They remind us that botanical art can illuminate not only the beauty of plants, but also the intertwined stories of ecology, culture, and our changing environment.
