【Episode 5】What is TAMA-HAGANE?
Japanese blacksmithing has over a millennium of history. It dates back to the 1st century A.D. when ancient blacksmiths studied template method from the continent. Copper pottery and rice farming techniques were also introduced to Japan at the same time.
Since then, Japanese blacksmiths had spent centuries to invent the traditional metal forging technique called TATARA(鑪). TATARA is a clay melting pot where you put iron sand and charcoal together to bond these chemicals with intensive heat.
By using this technique, they started to make Japanese swords out of Tatara carbon-steel.
This type of carbon-steel was later called TAMA-HAGANE (玉鋼; Ball-Steel). However, Tama-Hagane, in the early days, still had room for improvement. The schools of Katana (Japanese swords) continued carrying out various ways to make the best steel.
In the Edo period (1603-1868 A.D.), they finally achieved the most steady mass-producing supply of Tama-Hagane. As transport links in the Edo period were far more advanced than those of any previous eras, Tama-Hagane has rapidly spread throughout the country. It was widely used for Shin-TO Japanese swords, since it was deemed the purest form of carbon-steel with the most stable chemical bond. It was also a defining moment in Japanese history when most swordsmiths in Japan used virtually the same ingredient in their blacksmithing.
After the decline of the Samurai regime in the Meiji era (1868-1912 A.D.), Tatara and Tama-Hagane also vanished from Japan. Although it had once restored its use in the World War period, there was eventually no operating Tatara factory in Japan.
The Tatara method had been extinct until the 1970s. However, there was still no better metal material than Tama-Hagane in terms of its pureness and strength. Even the finest of modern technology could not create the alternative to Tama-Hagane.
In the year 1972, following all the struggles by the government and metal industry to bring Tatara back to life, it was NBTHK that presented themselves in charge.
They finally restored the traditional Tatara factory in the year 1977. Also, Tatara was selected as one of the traditional Japanese techniques that are legally worth preserving by the Agency for Cultural Affairs in Japan.
