Yakuza 5 Edit
The name "Mariko" was invented for the English release of Yakuza 3. In the Japanese version the character is only referred to as "Mama". While it IS possible that this could be her name, it is also possible that she is merely being referred to by her title of Mama-san, although this would imply she has no name.
