Satsuma Masayoshi was the second generation son of Masayoshi Ijichi and was born in 1733 bearing the name Chiemon Iji. He learned the technique of sword forging from the second generation Masayoshi, and mastered the forging techniques of Namiheiden and Soshuden. After his father’s death, he became the third generation and took the name Masayoshi. In the 4th year of Tenmei (1784), he was ordered to work for the Satsuma domain. He passed it on to his eldest son, and changed his name to Masayuki (engraved inscription: Masayuki Taira, the governor of Hoki).
In 1818 (1818), Masayuki continued to make swords steadily until his death at the age of 86. He is praised along with Suishinko Masahide of Edo. He showed a brilliant skill that surpassed his ancestors, and together with Genpei, he is a master craftsman who represents the Satsuma Shinshintou.

The main sword body arrangement is 2 shaku 3 sun nine and a half long. It is a sword that has a solid construction, just like the Satsuma clan Jigen style, and it looks like it will be cut in two. Jitetsu has a rough texture and a smooth texture. The blade crest is fired at the bay, and gradually increases the width of the burn to create a pattern that disturbs each other’s eyes. The blade is very bright and sharp, and you can see the master craftsmanship that was said to be one of the best Satsuma Shinshin swords. Fuko becomes straight and returns to Komaru. Most of the swords made in this period were cut with the Satsuma Sumi Masayoshi and Satsushu Sumihira Masayoshi signatures, but the swords cut with the Satsuma Kanko Chichibu Gotanehira Masayoshi signature are extremely rare. It seems to be an inscription that can only be seen around the 7th and 8th years of Tenmei.
