Master Shoemaker's Legacy: Blending Tradition and Innovation for the Next Generation of Footwear

Preserving a Legacy: The Journey of Koji Sasaki



At the age of 87, master shoemaker Koji Sasaki stands as a beacon of hope for the preservation of traditional craftsmanship in Japan. Born in 1939, Sasaki embarked on his shoemaking journey at just 15 years old, a commitment that has continued for over 70 years. His craftsmanship has garnered admiration from royalty, celebrities, and distinguished figures, all seeking the unparalleled comfort that only a product of his meticulous handwork can offer.

As his career develops into its twilight years, Sasaki faces the crucial challenge of passing his skills and techniques to the next generation, ensuring that the unique expertise of Japanese artisan craftsmanship continues to thrive amidst a rapidly changing world. In a surprising turn of fate, his most promising apprentice is a young man of mixed French descent, illustrating the international blend of influences now shaping modern craftsmanship. Together, they embody a unique partnership that crosses both cultural and generational boundaries.

The duo is tackling an ambitious project: the creation of the 'Ultimate Recovery Slipper'. This revolutionary product aims to merge Sasaki’s traditional knowledge—specifically his understanding of foot anatomy and sewing techniques—with the contemporary demand for recovery features that alleviate fatigue and enhance comfort. They are not just designing an indoor slipper; they aspire to develop a footwear solution that can heal and rejuvenate the feet of wearers from all walks of life across the globe.

“Tradition is maintained by continuously innovating,” Sasaki believes. By promoting this mantra, SANAX, the company that embodies Sasaki’s craftsmanship and vision, is set to introduce their next-generation slippers, combining masterful handcrafting methods with modern recovery technology to a global market.

Every day, regardless of rain or snow, Sasaki undertakes a 40-minute bicycle journey to his workshop, a testament to his dedication to his craft. This unwavering commitment reflects his desire not only to practice his art but to ensure that the skills and processes of traditional shoemaking are passed down to future artisans.

Looking ahead, SANAX plans to keep enthusiasts updated about this innovative project through their mailing list and official LINE account. As they embark on this new adventure, the anticipation is palpable.
