Kinboshi
It is believed that the term stems from the usage of the terms "shiroboshi" (lit: white star) to designate a bout victory, and "kuroboshi" (black star) to designate a bout defeat. Thus, a "gold star" designates it as a special victory. The word "kinboshi" first came into popular use in the Taishō period (1912-1926), and the system of monetarily awarding a "maegashira" who defeated a "yokozuna" in an official tournament began in January, 1930. A "kinboshi" victory increases the balance in the "maegashira"'s "mochikyūkin" account by 10 yen. This balance is converted using a multiplier, presently 4,000 , and added to the wrestler's bonus in every subsequent tournament in which he competes as a "sekitori". With six tournaments a year, this one victory corresponds to a pay increase of 240,000 yen per annum for the remainder of the wrestler's "sekitori" career. The "kinboshi" record is held by former "sekiwake" Akinoshima who won 16 bouts against "yokozuna" when ranked as a "maegashira". Restrictions. "Kinboshi" are not awarded to "san'yaku" ranked wrestlers who defeat a yokozuna, nor is it awarded if the "maegashira" beats a "yokozuna" with a default win (or "fusenshō"). It is also not given if  the "yokozuna" is disqualified for using an illegal move (or "hansoku"). Other uses. "Ginboshi" (銀星 or silver star) is also used informally to denote a "maegashira" victory over an "ōzeki." However, there is no monetary bonus for such a win, nor are official "ginboshi" records kept. The unofficial record holder for silver star victories is Aminishiki, with 47. The term "kinboshi" is used outside sumo in informal language. It can mean a major victory, or (in slang) a beautiful woman. List of "kinboshi" records. Tables for both "kinboshi" earned (by "maegashira") and those conceded (by "yokozuna") are given below.
