Johan, Trial by fire
Meet Johan Leutwiler, the first foreigner to become a recognized Japanese swordsmith
For centuries, Japanese sword-making has been an art form rooted in precision, patience, and deep cultural significance. Few foreigners have had the opportunity to immerse themselves in this ancient craft, but Johan Leutwiler, a Swiss-born blacksmith and Vitality Ambassador, has become the first foreigner to be officially recognized as a Japanese swordsmith. From a childhood fascination with metalwork to discovering his passion for Japanese swords at the age of 17, Johan has dedicated over half his life to mastering this ancient craft. Discover this journey of dedication, respect, and cross-cultural exchange below.

From Switzerland to Japan: A Passion for Steel and Fire
Johan’s path to becoming a bladesmith was anything but conventional. Growing up in the small town of Monthey in the south-western canton of Valais, nestled in the heart of the Swiss Alps, he was captivated by the process of shaping metal, leading him to pursue blacksmithing professionally. His interest in traditional Japanese swordmaking eventually drew him to Japan. Under the guidance of a renowned Japanese swordsmith, he refined his skills and deepened his understanding of this time-honored tradition through a five-year apprenticeship in Hiroshima. His dedication was recognized in 2024 when he received his sword-making license from the Agency for Cultural Affairs. His aspiration is to craft works of art that touch people’s hearts and showcase the excellence of traditional craftsmanship. Johan is also an ambassador for Vitality.Swiss, the communication program of the Embassy of Switzerland in Japan.

Discover the story of Johan’s journey into the world of metalworking, starting from his early inspiration to his decision to pursue a career in swordsmithing.
Due to the intense heat generated in our work, we primarily do forging in the morning. We prioritize the tasks requiring the highest temperature early in the day. In the afternoon, we focus on shaping, polishing, and finishing the swords. On sunny days, we also cut and sort charcoal outside for the forging work.
Becoming a swordsmith also made me realize the profound importance of Japanese swords for the Japanese people throughout history. They have significantly influenced various aspects of Japanese culture, including language and Shinto mythology. Even today, many Japanese use words derived from swords in their daily lives without realizing it.
There are numerous 1000-year-old swords still in existence today. Therefore, Japanese swords are believed to have a lifespan of 1000 years. Today, people are focused solely on innovating for the future, neglecting the importance of the past. In sword smithing, we ask ourselves: "Can we build something that will last for a thousand years?"
Sustainability in swordsmithing goes beyond maintaing a healthy life or sustainable practices; it also means ensuring the continuation of tradition. Discover Johan thoughts on what it means to be a Japanese swordsmith.
To train the next generation of swordsmiths, the Agency for Cultural Affairs provides support. Apprentices can take part in a 3-day training session twice a year, where they have the freedom to work. Some swordsmiths receive direct support from the Agency, ensuring the continuity of successor training. With about 200 swordsmiths currently, the new generation needs to innovate to prevent further decline.
I was able to start to learn from my master because I had intended to live permanently from the beginning. For me, to be a swordsmith is to be the successor and representative of a technique that has existed for 1,200 years, so I will never be complacent, and I will devote myself to it every day, with an attitude that would make my predecessors who created the sword industry proud.
This is also why I wish to become a Japanese citizen. I love Japan and it is natural for me to want to buy a house with my girlfriend here and work as a Japanese sword smith. Since I will be in Japan forever, there is no reason to keep my Swiss citizenship, on the contrary, being Swiss means I have to renew my visa every year.

Bridging Two Cultures Through Craft
Johan Leutwiler’s journey exemplifies the power of cultural exchange and the pursuit of excellence. His story is a testament to the enduring appeal of traditional craftsmanship and the connections it fosters across borders. Whether in Switzerland or Japan, we hope that the story of his dedication to his craft continues to inspire new challenges and new beginnings.
