因幡銀山（いなばぎんざん）は、鳥取県岩美郡岩美町（旧・巨濃郡銀山村）の三日月山にあった銀鉱山。巨濃銀山（このぎんざん）、岩美銀山、三日月山銀山とも呼ばれる。 羽柴秀吉によって鳥取城将に任ぜられた宮部継潤（法印）が、文禄2年（1593年）に初めて間歩（坑道）を開き、多量の銀を産出したという。 1500年代閉山。 現在も鉱山の間府の跡と思われる鉱口が残る。 銀山神社付近にも坑口跡が見られるらしい。
Inaba Ginzan (Inaba Ginzan) is a silver mine located in Crescent Mountain of Iwami cho, Iwami-gun, Tottori Prefecture (formerly Kinno-gun Ginzan village). It is also called Mino Ginzan (Ginzan), Iwami Ginzan, Mikatsukiyama Ginzan. Mr. Miyabe Seijun (the legendary staff) who was appointed to Tottori castle by Hashiba Hideyoshi opened the gallery for the first time in Bunko 2 (1593) and produced a large amount of silver. Close mountain in the 1500's. There still remains a mineral mouth which seems to be the remains of the prefecture during the mine. It seems that the site of the well hole can be seen near the Ginzan shrine.
