How to say "derby" in Japanese

• 山高帽子やまたかぼうし
  nounCovers only the hat: the hard, round-crowned felt hat called a derby in America and a bowler in Britain. It never means the race or a match, and is a less common name for it.
• ダービー
  nounThe loanword; it refers above all to the famous horse race. For the sports sense — a match between two teams from the same city — the fuller ダービーマッチ is the word to reach for.
• ダービーマッチ
  nounUsed only for the sports sense: a competitive match between two teams from the same city, what English calls a local derby. It does not refer to the hat or the horse race.

English 'derby' splits three ways: 山高帽子 names the round-crowned hat, 「ダービー」 refers chiefly to the famous horse race, and 「ダービーマッチ」 is a sports match between teams from the same city.
