MIYOSHI Nagamichi was grand-child of MIYOSHI Nagakuni who lived at Iyo, Matsuyama province.
His father Masanaga and his grand father moved to Aizu, following their feudral lord, KATÔ Yoshiaki, had been moved from Iyo to Ô-shû Aizu in Kanêi 4. Nagamichi was born in Kanei 10 in Aizu. Initially, he called himself Michinaga. In Manji 2, he was honoured the title Mutsu Daijyô, changed his name Michinaga. He had similar style of creating sword to Nagasone Kotetsu of Edo. He died in his 53 years old, Jôkyô 2.

It may be considered that the signature ura-mei "地鉄研真鍛" means creating the sword using "oroshi-gane" in very careful manner.

The meaning of character "研" : Taking the example TSUDA Sukehiro's created sword with ura-mei "以地鉄研造之" with nen-ki, Sui-shin-shi Masahide, swordsmith of Bakumatsu (end of Edo period) explained the meaning as creating swords using "卸し金" in his book titled "Tô-ken Jitsu-yô-ron".(Practical thinking on swords)
The use of oroshi-gane technique had been declining since direct forging technique of steel began to spread around Tenbun (1532-1614), however, HORIKAWA Kunihiro resumed to use oroshi-gane technique around Keichô (1596- 1614). TSUDA Sukehiro emulated to use oroshi-gane technique following "和泉守兼㝎"(Izumi-no-kami Kane-sada "nosada"), the use of technique declined again after around Genroku period.

Sui-shin-shi Masahide defined the term "oroshi-gane" in his book titled "ko-kon sei-saku-tô-ken ben-gi" as following : "In past years, they could get "zuku", "hagane" and "namagane" from iron mines but sometimes they re-brew in order to get target steel like the old swordsmiths. It called "oroshi-gane".

The meaning of "真鍛" : We can find the swords which have similar signature such as the sword of Ô-mura Kaboku "真十五枚甲伏造" or Kotetsu "真鍛長曾根興里作". The book which thought to be written by YAMANO Kaemon title "鉄鍛集", there was a section "真の鍛への事". It said that he used Izuha made fine quality materials, refining and stacking them with "mizu-beshi" process, mixing old irons and forging with "Jyû-mon-ji kitae" method.
