Kinboshi

Kinboshi, (Japanese , lit: gold star) is a notation used in professional sumo wrestling to record a maegashira victory over a yokozuna. In sumo a bout victory is normally called a shiroboshi (or white star) and a defeat kuroboshi (or black star), from the way the results are displayed in the tournament tables. The "gold" designates it as a special victory.A kinboshi victory increases the balance in the maegashira's mochikyukin account by 10 yen. This balance is converted using a multiplier, presently 4,000, and added to the wrestler's bonus in every tournament the wrestler competes as a sekitori. With six tournaments in 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.
