Accompanied by a certificate of registration as a Tokubetsu Hozon Token [Sword especially worthy of preservation] no. 148683 issued by the Nihon Bijutsu Token Hozon Kyokai [Society for the Preservation of the Japan Art Sword] on 9th August 2003
The smith was son of Omi daijo Tadahiro, the second generation of the Tadayoshi line (see Lots 431 and 444). Born in 1636 he received the title Mutsu daijo in 1660 when he was only 24, and the greater title Mutsu no kami in the following year. He died at the age of 50 in 1686. The swords made by this third generation Tadayoshi have always been regarded as closest to those of the first generation. This blade, with its very fine ko-nuka hada and broad suguha hamon can be compared with the piece by the first generation (see lot number 431) Tadayoshi made during his later life, and signed Hizen kuni Musashi no kami Tadahiro.
