Kappa Kanpeki - The fastest and easiest way to cut vegetables for sushi

Revolutionize Your Sushi Prep with the Kappa Kanpeki

Preparing vegetables for sushi—especially techniques like Katsuramuki—is essential in any sushi kitchen. However, it's often one of the most time-consuming and repetitive tasks at the sushi bar. The Kappa Kanpeki changes that. Whether you're working with daikon, cucumber, or other vegetables, this tool dramatically accelerates your Katsuramuki process—delivering consistent results in a fraction of the time. Even better, it does so at a significantly lower cost than most traditional Katsuramuki-assist devices.

See Why Customers Trust Kappa Kanpeki

  • “I was skeptical of the Kappa Kanpeki at first, but after it saved me during a busy Friday shift, I really began to like it! Now I can’t imagine using another method to prep cucumbers, there is simply no faster or easier way available on the market.”

  • “Perfect tool for sushi nights! Kappa Kanpeki makes slicing vegetables paper-thin and super quick—I finally get professional-looking cucumber sheets every time. It took a few tries to get the technique down, but once I got it, I was making sheets of cucumber and zucchini in seconds!”

  • “I have many students at my sushi classes, and Katsuramuki has always been a challenge to teach in a short time. Now I just give a demonstration of the traditional technique, and then have my students practice with the Kappa Kanpeki. They can see where the technique comes from, and get immediate results quickly and safely!”

Our Story

I'm Ethan, a sushi enthusiast since childhood. My love for sushi led me to Tokyo during my studies, where I ate at a different sushi restaurant almost every day. Returning home, local sushi just wasn’t the same anymore. So, I began to teach myself the art of sushi, which is much easier said than done. After years of experience in Europe’s best sushi restaurants, my skills began to improve. Along the way, I encountered problems with the status quo, which inspired me to create the Kappa Kanpeki. Now, I aim to share my inventions, easing sushi preparation while honoring Japanese traditions that inspire me.

  • Kappa Kanpeki will work with most dense cylindrical vegetables: Cucumbers, Daikon Radish, Apples, Potatoes, Zucchini, and Eggplant are the most common we use it with, but feel free to test it with others! It is important that whatever you cut is firm and not too soft, otherwise it may be more difficult.

  • Kappa Kanpeki works best with single bevel Japanese style knives like Usuba or Yanagiba. However, it should work with any sufficiently long and sharp knife! Test out a few of your knives and let us know which works best!

  • We take a lot of inspiration from Japanese culture here at Smart Sushi Chef, and “Kappa Kanpeki” is no different. Translated from Japanese, it means “Perfect Cucumber”.
