Hizen Tadakuni (fss-762)



The Hizen Tadayoshi school of sword smith’s needs no introduction, and are highly prized worldwide.

 It all began with the Shodai Tadayoshi who was born in 1572, and known as Hashimoto Shinsaemonjo. Shodai Tadayoshi at age 25 became an apprentice to Umetada Myoju in Kyoto, who is known as the founder of the Shinto Sword. The “Tada” character was given to him by Umetada. After a three year apprenticeship Tadayoshi returned to his home in Hizen Province, where he set up the Hizen Tadayoshi Kaji. The Hizen Tadayoshi Kaji extended through nine mainline generations, ending with the death of the 9th generation Hizen Tadayoshi in 1880.

Roger Robertshaw, author of the book “The School of Tadayoshi”, is one of the foremost authorities and collectors of the Hizen Tadayoshi School. In his book, Mr. Robertshaw states, “The Tadayoshi line were the mainline swordsmiths, but equally  as good works were produced by their family and students such as Tadakuni and their descendents.”  As well he states, “Anyone who has had the chance to handle the works of Tadakuni will readily attest to their quality. Blades by this master will immediately impress you as awesome and powerful weapons.

The 1st generation or Shodai Hizen Tadakuni was the son of Hizen Yoshiie.  Hizen Yoshiie, the brother and student of Shodai Tadayoshi, worked c. 1625, and his works were rated Josaku.  Hizen Tadakuni, was known to have produced swords of equal quality of any  the mainline Tadayoshi smith’s. Tadakuni’s works were rated Josaku by Fujishiro for his skill and Wazamono in the “Kokin Kaji Bikosen” by Yamada Asauemon Yoshichika
