About us

Our Brand Story

Kasumi Japan began with a personal journey.

In early 2023, our Founder & CEO, Mr. Johnny, traveled to Seki City (Gifu Prefecture), widely recognized in Japan for its long-standing blade and sword-making heritage and its modern knife-making excellence. What struck him wasn’t just sharpness or aesthetics; it was the discipline behind performance: steel selection, heat treatment, grind geometry, balance, and finishing, done with the quiet confidence of makers who have refined their craft over generations.

That experience became the start of a deeper journey. Mr. Johnny spent the following months visiting workshops, speaking with craftsmen, and learning what separates a truly great Japanese knife from a generic “Japanese-style” product. He also heard the same frustration repeatedly from chefs and serious home cooks: finding knives that are authentically made, transparently sourced, and correctly matched to real kitchen needs has become harder than ever.

In 2024, Mr. Johnny established Kasumi Japan LLC in Kasumi-ku (Kami, Hyōgo). For us, “Kasumi” is not a claim about bladesmithing history; it is a commitment to culinary authenticity, Japanese standards, and a slower, more deliberate approach to quality.

Where our knives come from

We source our knives from specially selected knife makers, both here in the Kasumi area and from several other respected knife-making districts across Japan. This includes relationships in established blade regions such as Seki (Gifu) and Sakai (Osaka), alongside additional specialist workshops, where we evaluate for consistency and craftsmanship. 

Our approach is hands-on and performance-led. We select knives based on fundamentals that matter in real kitchens: heat-treatment consistency, geometry, edge stability, balance, fit and finish, and long-term reliability, not trends or exaggerated claims.

Our Mission

To deliver authentic Japanese knives that elevate everyday cooking by sourcing from trusted makers in Japan, prioritizing performance over hype, and building long-term customer trust through transparency and service.

Our Values

Craftsmanship First: We respect the maker. We prioritize steel integrity, heat treatment, grind geometry, and finishing because a knife must perform before it can impress.

Authentic Sourcing: We work with specially selected makers in the Kasumi area and across Japan’s knife-making districts, including renowned regions like Seki and Sakai.

Performance in Real Kitchens: We curate knives designed to work beautifully every day, balanced, purposeful, and reliable for both professionals and serious home cooks.

Integrity and Transparency: We speak plainly about what a knife is, what it’s for, and why it matters, so customers can choose with confidence.

Long-Term Trust: We are building a brand people return to for years, not for trends, but for tools they genuinely rely on.
