This wakizashi is the work of a master craftsman who was active in Hizen Province during the Kan'ei era in the early Edo period, making it an extremely rare and valuable collector's item. The entire blade has already been polished, and it is in superb condition with absolutely no flaws on either the front or back surfaces. There is an extremely fine scratch on the mine. The jigane features a very tightly packed koitame grain with some mokume mixed in, and it exhibits excellent jinie. The hamon is naka-suguha with deep ni-oi, exuding an air of elegance. Of particular note is the o-boshi tip, which presents a truly imposing appearance.  On the sashi-omote side of the nakago, only the phrase “resides in Hizen Province” is carved, and the characters below have been cut off by the suriage. On the sashi-ura side, it is carved that the work of the original Tadayoshi was suriage at the request of Mr. Sagara. The sashi-ura appears to have been carved later, after the suriage was performed. In May 1985, the Society for the Preservation of Japanese Art Swords certified this wakizashi as the work of the second-generation Tadahiro and issued a preservation certificate recognizing it as a work of high value worthy of preservation for future generations. Tadayoshi was a disciple of Umetada Myoju, a master craftsman known as the “founder of Shinto,” and was also the de facto founder of the Hizen school, one of the major schools of Japanese sword making during the Edo period. When Tadayoshi passed away in 1632, Tadahiro became the second-generation head of the family at the young age of 19. He received the title of Omi Daijo in 1641 and passed away in 1693. It is said that he continued to wield his hammer until his final moments, with a career spanning over 60 years. Among Hizen swordsmiths, he left behind the greatest number of outstanding works. This is an extremely rare and valuable O-boshi Wakizashi by Tadahiro. Furthermore, the name of the person who commissioned the suriage is engraved on the sashiura of the nakago, giving it significant historical value.
