The Owari Tokugawa branch is one of the three families of the Tokugawa clan originally descended from Tokugawa Yoshinao (circa 1602-1650 AD), the ninth son of Tokugawa; Ieyasu (circa; 1543-1616 AD) followed by a long list of Daimyo thru to today and finally to the gentleman from whom I purchased this beautiful blade.

Hizen Ju Harima-Daijo Fujiwara Tadakuni who was born in 1604 AD, served exclusively for and under the Hizen Lord Nabeshima Motoshige. He first signed his swords with the name of Hironori. In 1634, he received the title Harima Daijo at which time, he changed his name to Tadakuni. In 1661, he had his title upgraded to Harima No Kami, his father and teacher was Hizen Hirosada.

During his lifetime, Tadakuni perfected his art and produced many magnificent blades. Tadakuni is deemed to be one of the most skilled of top Hizen Smiths. He died on the 22nd of April in 1691 at age 87 after a long and distinguished career.

A personal note: I had admired this sword owned by Tokugawa Yuji for quite some time and I am extremely proud and fortunate to have been able to purchase this blade from him.

In support of this sword, there is a Sayagaki (attestation) by Dr. Kanzan Sato, amost distinquished sword scholar written on the Shirasaya attesting to its' authenticity, along with this is a document from the sword museum in Tokyo known to sword students as the NBTHK in the form of a certificate of Tokubetsu Hozon quality (especially precious)
