Hagoromo chalk has risen beyond its function as a classroom staple, achieving near-mythic status among mathematicians, artists, and educators worldwide. Known for its almost ethereal smoothness, vibrant colors, and durability, it has become a ‘cult item’ for those who seek the best in their craft. Hagoromo’s quality has been lauded in places like YouTube’s Great Big Story, which has amassed over 18 million views for its feature on the chalk. Despite competition from digital tools, the chalk’s resilient reputation remains unmatched.

Survival Through Adversity

Founded in Nagoya, Japan, in 1932, Hagoromo experienced many setbacks, including factory destruction during World War II. Nonetheless, production resumed in 1947 and reached its peak in the early 1990s. However, by 2014, as whiteboards and digital tools dominated classrooms, sales began to decline. Facing aging and health concerns, third-generation owner Takayasu Watanabe announced the company would cease production, drawing a close to nearly a century of craftsmanship.

A Partnership Across Borders

The brand’s story took an unexpected turn when South Korean entrepreneur Shin Hyeong-seok visited Watanabe. For years, Shin had been importing Hagoromo chalk, and he proposed a daring idea: to move production to South Korea. Despite skepticism, Watanabe eventually entrusted Shin with the factory machinery, allowing Hagoromo to continue its legacy in Korea. In doing so, they crossed a border that has historically symbolized tension, establishing a partnership that represents both preservation and unity.

An Everyday Object, a Global Impact

Today, Hagoromo’s reputation spans far beyond Japan and Korea. David Eisenbud, director of the Mathematical Sciences Research Institute at UC Berkeley, first discovered the chalk at the University of Tokyo. Captivated, he soon found himself importing it to the United States, where it remains highly regarded. “I thought chalk was just chalk,” he recalls, “but I was wrong.” His dedication has helped bring Hagoromo’s story to the world, allowing a piece of history to be shared with future generations.

Hagoromo chalk is more than just a tool. Loved by Fields Medalists and respected by scholars worldwide, it stands out for its exceptional quality and durability, carrying a unique cultural significance that bridges intellectual tradition and connects generations, even in the digital age.
