How to say "ahead" in Japanese

• 前方ぜんぽうCommon
  no-adjectiveSpatial 'ahead': the area or direction in front, as of a moving car or person. It names the space ahead rather than an action, so it suits descriptions of position and direction.
  我々われわれははるか前方ぜんぽうに他ほかの船ふねを見みた。↗

  We saw another ship far ahead.
• 向こうむこうJLPT N5approx.Common
  nounAlso spatial, but for something further off — beyond a point, over there, in the distance — rather than directly in front. Use it when the thing ahead lies past some reference point.
  その男の子おとこのこは向むこうにいます。↗

  The boy is over there.
• 先方せんぽうCommon
  no-adjectiveGlossed 'ahead; in front', yet this is seldom the word you want for spatial 'ahead'; it normally means the other party in a deal or correspondence, or the destination. Prefer 前方 or 先に.
• お先におさきにJLPT N2approx.Common
  adverbThe polite set phrase for going or leaving ahead of others: said when excusing yourself first, as when leaving the office or a gathering before everyone else. Not a general word for spatial 'ahead'.
  どうぞ、お先さきに！↗

  Go ahead!
• 先にさきにJLPT N1approx.Common
  adverbThe adverb: doing something before someone or something else, or earlier; also used for going ahead of someone along a route. It covers both 'before (someone else)' and 'ahead (of)'.
  私が先さきにそこへ着つくよ。↗

  I'll get there before you will.

For physical space choose 前方 for the area directly in front and 「向こう」 for something further on or beyond; 「先に」 is for going or acting before others (「お先に」 when leaving politely), while 先方 rarely means 'ahead' at all.
