Mokumegane in Kanji

"Mokumegane" or "Mokume Gane" was named so, because its pattern looks like mokume - "wood grain".

"Gane" means "metal" in general and, if it used as a single character, it means "gold".

Some people use different kanji (Chinese) characters (above right) , especially in Akita Prefecture which is the birth place of mokume gane.
(In this case, "gane" means "copper")
