Hizen kuni ju Musashi Daijo Fujiwara Tadahiro Katana

The Hizen school centered in Saga town on the western side of Japan was one of the glorious successes of the Shinto period. It is founded by Hashimoto Shinsaemonjo who took on the art name of Tadayoshi, under the sponsorship of the daimyo Nabeshima Naoshige. The house style is based on the work of Yamashiro Rai, and swiftly gained and maintained a reputation for high quality swords, both beautiful and practical with excellent cutting ability.

Tadayoshi was born in 1572 and began learning sword-craft at the end of the koto period. His father was a swordsmith of average average ability who signed under the name Michihiro. His lineage descends from the Sa school. Michihiro died in 1584 and Tadayoshi was orphaned. His father and grandfather (Morihiro) were both in the service of the Nabeshima daimyo and at the time of his father's death, Tadayoshi was too young for service. Instead he took up sword crafting in the village of Nagase-Mura.

At the age of 25 with some 12 years of study under his belt, Tadayoshi had entered the service of Nabeshima Naoshige as a swordsmith, and was sent to study under the great master Umetada Myôju in Kyoto. Myôju was able to produce high quality copies of the work of Shizu and Sadamune, and early Tadayoshi work of this period follows his teacher in exploring these forms.

After three years under Myôju, Tadayoshi returned to Hizen and with funds made available through the Nabeshima daimyo he set up his forge and took on sixteen relatives and 60 or so local workers under employment in sword manufacture.
Tadayoshi would die on August 15th of 1632
