These craftsmen forge Japanese swords through the intricate process of heating and hammering iron into shape. Swordsmithing has deep roots in Japanese history and culture, and even today, their craftsmanship continues to captivate people worldwide.
In this article, we’ll explore what katanakaji do, the history of Japanese swordsmithing, the mythical god of swordsmiths, regions famous for katanakaji, and their appearances in the game Nioh & Nioh 2.
What Is Katanakaji?
I’m very interested in Katanakaji after watching the anime Demon Slayer.
Then let’s talk about Katanakaji today!
The Role of Katanakaji
Katanakaji are artisans who forge Japanese swords through a delicate and demanding process. Their main tasks include:
- Heating and hammering iron to create the shape of the blade
- Applying hamon (blade tempering patterns) through heat treatment
- Engraving their signature (mei) on the blade
The work requires exceptional skill, precision, and years of practice. However, sword-making is not a one-person job—katanakaji are just one part of a larger team.
Swordmaking as a Collaborative Effort
Japanese sword production is a collaborative process involving many specialized craftsmen:
| Miners | Extract raw minerals |
| Iron sand collectors (Kanna-ji) | Gather and purify iron sand |
| Tatara masters | Use the tatara furnace to refine iron |
| Charcoal burners (Yamako) | Produce charcoal for the forge |
| Engravers | Carve Sanskrit characters or decorative motifs into blades |
| Scabbard makers (Sayashi) | Craft custom scabbards to fit the sword |
| Polishers | Sharpen and polish the finished blade |
Each step requires unique expertise, and the combined efforts of these craftsmen result in a single masterpiece.
Who Is Amanomahitotsu-no-Kami?
The Mythical God of Swordsmiths
Amenomahitotsu-no-Kami is regarded as the patron deity of swordsmiths in Japanese mythology. This god is mentioned in the Nihon Shoki (Chronicles of Japan) and is believed to have forged the legendary Ame-no-Murakumo-no-Tsurugi （天叢雲剣）sword for Amaterasu, the sun goddess.
The deity of Tatara steelmaking, Ame-no-Mahitotsu-no-Kami (Amenomahitotsu no Kami), is said to have one eye and one leg, sharing many similarities with the giant Yokai Daidarabocchi.
Here’s the article about Daidarabocchi
I believe in some interpretations, Daidarabocchi is shown with one eye, one leg and two big long arms. Who know which one is correct. Also, I read a theory that Ippon Datara spawn and fell of Ame-no-Mahitotsu-no-Kami thus getting some of its features.
