How to say "consumer" in Japanese

• コンシューマーCommon
  nounA katakana loanword covering 'consumer'. It appears mostly in business, marketing, and product-category talk, such as consumer-facing versus professional equipment. In ordinary sentences about people buying goods, 消費者 is usually the more natural choice.
• 消費者しょうひしゃCommon
  nounThe default word for a consumer in the economic sense: a person who buys and consumes products or services. It is the standard term in news, law, advertising, and consumer-protection contexts, and works for both individual buyers and consumers as a group.
  米国べいこくにおいて「リベート」は、主おもにメーカーが消費者しょうひしゃに直接ちょくせつ提供ていきょうするインセンティブ手段しゅだんとして広ひろく認識にんしきされている。↗

  In America 'rebate' is widely recognized, generally as an incentive where makers give back directly to consumers.
• 使い手つかいてCommon
  nounCovers a consumer or user in the sense of the person who actually handles and uses something, with a nuanced, slightly subjective flavor. Also means 'employer'. Suited to discussions of craftsmanship or how well a product serves its users rather than to economic contexts.
• 利用者りようしゃCommon
  nounRefers to the user or consumer of a service or facility — a patron of a library, transport system, website, or shop. Choose it when emphasizing people who take advantage of a service, rather than purchasers in the economic sense.
  私が関心かんしんがあるのは車くるまではなくその利用者りようしゃの方ほうだ。↗

  It is not the car but the users that I am concerned about.
• 使用者しようしゃCommon
  nounGlossed as 'user; consumer', but in practice it is most often the word for 'employer' or for the person legally using something, such as an equipment user. It is seldom the word you want for the everyday economic sense of 'consumer'.
  特定とくていの文脈ぶんみゃくでどんな語ごを使つかうべきか知しっている人ひとは語ごの有効ゆうこうな使用者しようしゃである。↗

  An effective writer is one who knows what sort of words should be employed in any specific context.

For the economic sense of 'consumer' choose 消費者 (or the katakana 「コンシューマー」 in technical or loanword contexts); for someone actually using something, 利用者 or 「使い手」 fits best, while 使用者 usually means 'employer'.
