But surely NOT fluent in Eigo.
Myochin (明珍)
A school name of armor makers, Kamakura period – Bakumatsu, Made Kacchu (甲冑), Gusoku (具足), iron products, tsuba, etc.
According to the genealogy of Myochin family, “Izumo (no) kami Ki (no) Munesuke (出雲守紀宗介)†in Kenkyu era (建久: 1190-1199) of Kamakura period was the 1st generation and the lineage continued to “Shikibu Ki (no) Munesuke (式部紀宗介)†22nd generation (ca. Genroku (元禄)), although the matter cannot be believed. Even only about tsuba making, there were many makers who professed themselves Ki clan (紀氏) and chiseled individual mei as “Mune+something (宗某)â€. A mei of “tenka ichi Myochin saku (天下一明珍作)†is known on a iron bit with Gyoyo-mon (杏葉文) which was designated as a Juyo-bijutsuhin (重要美術品) in 1939. And works with two letters mei “Myochin (明珍)†are known as iron ornaments, bits, tsuba, and so on in late Edo period.
