Visit to Fusahiro Shimojima's forge

Experiencing the art of japanese swordsmithing first-hand

At Supein Nihonto, we believe that understanding a Japanese sword begins long before the blade is polished, mounted, or certified. It begins in the forge, where steel, fire, tradition, and spirituality come together through centuries-old techniques passed down from master to apprentice.
To better understand this extraordinary craft, we travelled to Japan to visit the forge and workshop of renowned swordsmith Fusahiro Shimojima (房宙), one of the contemporary Japanese masters dedicated to preserving the ancient art of traditional sword making.
The purpose of our visit was not only to commission a custom-made Japanese sword, but also to witness first-hand the entire forging process and gain a deeper appreciation of the dedication, discipline, and spiritual commitment required to create a true Japanese blade.

The forge: where tradition meets the sacred

Unlike modern industrial manufacturing, traditional Japanese swordsmithing remains deeply connected to spiritual beliefs and centuries-old rituals.
Upon entering the forge, one immediately notices the white ceremonial ropes, protective amulets, and Shinto symbols surrounding the workshop. These are not decorative elements but expressions of a philosophy that sees sword making as a sacred act.
For Fusahiro Shimojima, forging a sword is not simply the shaping of steel. It is a union between earth and heaven, between human craftsmanship and divine inspiration. As he explained during our visit, the swordsmith seeks perfection through discipline, humility, and respect for the blessings of the gods.
This spiritual approach is reflected even in the immaculate white garments traditionally worn inside the forge, symbolising purity and dedication to the craft.

The forging process

One of the greatest honours of our visit was being invited to participate directly in the forging process.
Standing before the roaring charcoal furnace, surrounded by intense heat and glowing steel, provides a perspective impossible to obtain through books or videos. The experience offers a profound understanding of the physical effort, concentration, and technical mastery required to transform raw tamahagane steel into a Japanese sword.
As Fusahiro Shimojima remarked, working at the forge brings a person closer to the divine. After witnessing the process first-hand, it is easy to understand why generations of swordsmiths have viewed their profession not merely as a trade, but as a lifelong calling.

The creation of a japanese sword

Every traditionally made Japanese sword is the result of countless hours of labour and collaboration between highly specialised craftsmen.
The process begins with the forging and folding of tamahagane steel, followed by shaping, differential hardening, polishing, mounting, and finishing. Each stage requires years of training and specialised knowledge.
A completed sword may take well over a year to produce from start to finish.
Furthermore, a master swordsmith is legally restricted in the number of blades he may create each year. Most active smiths produce only six to eight swords annually, ensuring that each blade receives the attention and care required to meet the highest standards of Japanese craftsmanship.

Meeting master swordsmith Fusahiro Shimojima

During our visit, Fusahiro Shimojima generously shared examples of his work and explained the philosophy behind his craft.
His blades display a remarkable balance of elegance, activity, and precision, characteristics that place them firmly within the tradition of the great historical masters. While each sword remains unique, the quality of workmanship demonstrates why contemporary Japanese swordsmiths continue to be highly respected by collectors around the world.
The opportunity to discuss the details of blade construction, forging techniques, and aesthetic choices directly with the smith offered invaluable insight into the world of modern Japanese sword making.

Preserving a living tradition

Today there are approximately three hundred licensed swordsmiths in Japan. However, many have already retired, and the number of actively forging masters is considerably lower.
This makes every traditionally forged Japanese sword increasingly significant as both a work of art and a cultural artefact.
The preservation of this craft depends on the dedication of masters such as Fusahiro Shimojima, who continue to uphold centuries of knowledge while passing their expertise to future generations.

I received a beautiful tokubetsu hozon nihonto for Christmas from Supein. Actually my wife purchased the sword after receiving some helpful hints and recommendations lol. She knows absolutely nothing about nihonto but Supein walked her through everything honestly and I ended up with something beyond my dreams and expectations, honestly. The packing was exceptional, shipping fast and the sword itself a literal work of art. Supein has a lifetime customer now as my collection grows. Thank you!

I had been looking for a tachi with a lot of curvature for a long time and I called Supein Nihonto. They didn't have any tachi with the sori I was looking for, but I was treated with a lot of love and professionalism and we were talking for a long time. The next day I received a call from the shop, telling me that they had received new swords and that there was a tachi with a lot of sori. That same afternoon he already had a lot of photos of the sword and its measurements. I found the price good, especially if I compared it to other Spanish sellers of Nihonto. The shipment took a day and the package arrived in perfect condition, as the person in charge of the packaging puts a lot of effort into the work and the result is a strong packaging. Without a doubt, Supein Nihonto is my 100% recommendation!
