Sachiko Yamaguchi

My name is Sachiko Yamaguchi. My family name is Yamaguchi. "Yama" has a meaning of "mountain". The second character means "mouth". ("Mouth" is "kuchi", but when it's written as the second of two characters, it is pronounced "guchi".)
My first name is Sachiko. I was given this name by my grandmother because she likes "Sachi", which is the usual first character in the name "Sachiko". But my name is "Sachiko". I don't know why.
