About Japanese Knife Lab
Who We Are
Our Mission
Japanese Knife Lab exists to bridge the gap between Japan's centuries-old knife-making traditions and an international audience hungry for authentic knowledge. We believe that understanding a knife goes far beyond specs and price tags — it requires hands-on experience, cultural context, and genuine expertise.
Our goal is simple: help you discover, understand, and choose the right Japanese knife through expert reviews, in-depth guides, interactive shop maps, and cultural storytelling — with every article saying whether it rests on our own visits and tests or on makers' published specifications.
Our Expertise
Two Hands-On Tests
Our own hands-on testing so far is two tests in Kappabashi, Tokyo: six santoku bought at six shops and cut side by side in April 2026, and one knife sent to five shops for sharpening. Every other recommendation is compared on makers' published specs, steel, hardness and price, and is labelled as such. Our methodology.
Steel Knowledge
From White Steel #1 and Blue Super to VG-10 and ZDP-189 — we understand the metallurgy behind each blade. Our reviews explain how steel type affects sharpness, durability, and maintenance.
On-the-Ground Research
Our Kappabashi shop directory is built from actual visits, not aggregated listings: our editors have visited every shop in it. Shop facts are checked against primary sources.
Our Editorial Team
Japanese Knife Lab Editorial Team
Japanese knife specialists — Tokyo, Japan
The Japanese Knife Lab Editorial Team is a Tokyo-based group of editors and researchers specializing in Japanese knives. We have visited every shop in our Kappabashi directory, and we cover blade-making regions including Sakai, Seki, Echizen, Tsubame-Sanjo, and Tosa from makers' published information and primary sources.
Every review and guide on this site says what it rests on — one of our two Kappabashi tests, our shop visits, or makers' published specifications (see our methodology). Our mission is to make Japanese knife culture accessible to enthusiasts worldwide, combining deep local knowledge with clear, trustworthy content in four languages.
Editorial Policy
Clear Sourcing
Each article says what it is built on: our two hands-on tests in Kappabashi, our shop visits, or a comparison of makers' published specs, steel, hardness and price. Shop facts are checked against primary sources. We never publish simple summaries of other sites or copy from manufacturer catalogs.
Price & Spec Transparency
Prices, steel types, and sizes reflect information verified at the time of publication or from official sources. Dynamic data is reviewed and updated periodically.
Affiliate Disclosure
Some links on this site may generate affiliate commission. We only recommend products our editorial team has independently evaluated, regardless of commission.
Continuous Updates
When new steels or products launch — or when our reporting uncovers new information — we revise existing articles so the content stays accurate.
