Experience the World of Japanese Swords and Polishing at a Master’s Workshop in Tokyo

Buneido: A Sword Polisher’s Workshop with a Collection of Japanese Swords

Buneido, a workshop run by sword polisher Masaru Nemoto, is located in Tokyo's Setagaya Ward, just a short distance from the famous Shibuya area. Nearby is Gotokuji Temple, known as the birthplace of the maneki-neko, or lucky cat. Inside the workshop, you’ll find a collection of swords of various lengths, along with other sword-related crafts like sheaths and guards on display.

Japanese swords are gaining even more attention thanks to the rise of pop culture, like anime and movies

Masaru Nemoto, the instructor and sword polisher for this experience plan, brings new brilliance to Japanese swords at Buneido. Inspired by iaido, Nemoto trained under the late Jiro Shiokawa, mastering the techniques and spirit passed down by his mentor. This exclusive experience allows you to immerse yourself in the world of Japanese swords at Buneido, where you’ll learn about their history and craftsmanship through the art of sword polishing.

A Symbol of Japanese Spirituality and Aesthetics

The experience begins with a brief lecture on the history and art of Japanese swords and their polishing. Integral to Japan's history and culture, Japanese swords trace their origins back to the 3rd to 6th centuries with the advent of ironworking. Early swords were straight and double-edged, but by the 10th to 11th centuries, the iconic curved swords, ideal for horseback combat, emerged. Over the centuries, Japanese swords evolved alongside the nation's shifting needs and traditions.

The Muramasa sword, made around 400 years ago and owned by Nemoto, is known for its weight and beauty

In Japan, there is a well-known saying: "The sword is the soul of the samurai." Samurai regarded their swords as extensions of themselves, symbols of bushido embodying their soul and honor. However, even the finest swords, forged by the most skilled artisans, require meticulous care to preserve them. This became especially important after the Edo period, when Japanese swords were valued not only as weapons but also as works of art, making the role of a polisher indispensable.

A polisher’s mission is to preserve the sword’s original condition through careful polishing

Appreciate the Art of Steel

After covering the basics and history of Japanese swords, Nemoto will demonstrate the art of sword polishing. This process is divided into two main stages: "base polishing," which removes rust and defines the blade's shape, and "finish polishing ," which brings out its polish and brilliance. The entire process involves at least seven types of whetstones and typically takes two to three weeks to complete a single sword. In this demonstration, you will observe the first step of base polishing , called "aratogi" (rough polishing), and the final step of finish polishing, called "uchigumori."

Special tools and chairs are used; mastering the proper sitting posture can take months

When Nemoto begins sliding the Japanese sword across the rough whetstone, a sharp, intense sound resonates through the workshop as steel grinds against stone. In contrast, the process with uchigumori whetstones is almost serene. "The rhythmic sound, like a heartbeat, shows that the force is being correctly transferred to the blade," Nemoto explains. The workshop falls quiet, with only the soft, rhythmic clinking of tools breaking the silence.

Finally, it’s your turn to try polishing. Using the same rough whetstone and uchigumori as demonstrated, Nemoto will guide you through the process with detailed instructions on posture, tool handling, and foot positioning. If sitting low is challenging, arrangements can be made in advance to accommodate your needs. (The whetstone used during the experience may change each time.)

Once you’re comfortable, you can focus for hours—a polisher’s ideal position

Once you’ve learned how to hold and move the sword, you’ll begin polishing it yourself. You’ll notice the weight and cool touch of the steel, as well as the subtle vibrations that travel through your fingertips with each motion. While it may seem challenging, Nemoto’s clear and patient guidance ensures a smooth experience. Through hands-on practice, you’ll gain a deeper appreciation for the polisher’s craft and extraordinary skill. Take your time and enjoy this rare opportunity to connect with the sword on a deeper level.

Focus all your senses on the sword and your hands

A Unique Opportunity to Discover the True Greatness of Japanese Swords

The experience wraps up with a relaxing tea time with Nemoto, where you can share your thoughts and impressions from the day. While there are specific rules and procedures for purchasing a Japanese sword, you’ll also have the opportunity to buy small knives crafted using the same traditional techniques.
