A Day in Kosen Ohtsubo’s Flower Planet

I first encountered Kosen Ohtsubo’s work many years ago, and it left a lasting impression on me. His distinctive approach to ikebana goes beyond the traditional art form, inspiring a deeper appreciation for how he intertwines nature, memory, and sound in his creations.

Nestled in Japan, Flower Planet serves as both Kosen Ohtsubo’s home and studio, a sanctuary where he nurtures his deep passion for ikebana. At 85 years old, Kosen is regarded as one of the foremost ikebana artists in the world. A distinguished judge in prestigious ikebana school competitions, he has held numerous global exhibitions and collaborations that further solidify his influence within the art world. He is a proud member of the Ryuseiha school, celebrated for its innovative approach to ikebana, and his work continues to evolve with remarkable depth and complexity.

“It’s like a fight.”

“It’s like a fight,” Kosen says, describing the inner struggle that infuses each arrangement with purpose and meaning. For him, ikebana transcends being merely a creative practice—it becomes a means of protest, a way to challenge the injustices he saw in the world. “When I was young, I started doing ikebana as a form of protest,” he reflects, his voice imbued with quiet conviction, as he sits amid the tranquil arrangements that fill his studio. “I was deeply frustrated by certain aspects of the world, and ikebana became a way for me to express that anger.” His connection with ikebana goes beyond technique—his practice is a thoughtful philosophical exploration, an intentional act of questioning societal norms and redefining artistic expression. “It can help ease the heart and mind,” he shares, highlighting its meditative power.

Kosen’s process is a delicate conversation between nature and human intervention, a refined dance that demands patience and precision. Each flower, each stem, is chosen and arranged with the utmost care and sensitivity—that of a poet delicately crafting words. “Ikebana is a way to communicate with the world,” he shares, his hands deftly weaving each narrative together.

At the heart of Kosen’s practice is a commitment to the timeless beauty of ikebana, and his recent exhibit in Germany marked an exciting new chapter in his artistic journey. Presented as a tribute to decades of creative mastery, the exhibit offered a glimpse into his artistic progression, reflecting a lifetime spent exploring the intersection of form, feeling, and philosophy.

“Although I’m gradually losing my hearing, I still hear the music through my memory.”

Kosen’s Flower Planet is a space where his dual love for sound and nature thrives. In fact, Flower Planet was designed to envelop him in his environment. It features speakers embedded in the walls, allowing music to flow around him as he works. His once vast collection of over 2,500 LPs and 500 CDs now occupies only a small part of his shelves, a testament to years of curating a sonic landscape. “Although I’m gradually losing my hearing, I still hear the music through my memory,” he reflects, his voice carrying the weight of those years. Though he has let go of much of his collection, he continues to enjoy music-related posts on Facebook, where the sounds of the past remain vivid in his mind. Music, in all its dimensions, remains a constant companion to his creative process.

Even in its stillness, Flower Planet is filled with the unspoken presence of sound—an echo of the music he recalls, and the language of the flowers that speak to him through their forms. In this harmonious space, beauty and silence converge, and Kosen’s art emerges, where music and nature, though absent of sound, continue to shape his world.
