Oumi-daijo Fujiwara Tadahiro, his real name is Hashimoto Heishiro (later changed to Shinzaemon), a bastard son of the first generation Tadayoshi, born in the 19th year of Keicho (1614) and succeeded the second generation of Hashimoto family when he was only 19 years old. He entitled Omi-daijo when he was 28 years old in the 22nd day, the 7th month, 18th year of Kanei (1641). He had established the firm foundation of Hizen Tadayoshi families that had succeeded until the early of Meiji period. Passed away in the 27th day,the 5th month, 6th year of Genroku(1693), was 80 years old.
This is the typical work of a heavy-bulit Uchi-Katana (single-hand style sword) of the second generation TADAHIRO. It is amazing that this sword still remains the ample thickness with high shinogi-ridge and holds an original shape of good proportion. The length of cutting edge (One-shaku, nine-sun, nine-bu and five-rin), would be because of the regulation for the length, but also would be an exclusively made for Samurai owner who wanted moderate sized katana for common use. It is marvelous that this katana still remains an almost original condition over 330 years to say in an excellent condition (Using a scale of mint-excellent-very good-good-fair-poor).
