How to say "explorer" in Japanese

• エクスプローラ
  nounThe loanword. In Japanese it appears chiefly in software and product names, so it is seldom the word you want for a human explorer — for that sense 探検家 is the natural choice.
• 探検家たんけんか
  nounAn explorer as a person — someone for whom exploring unknown regions is a profession or calling. The natural choice in biographies, history books and news about expeditions.
  第だい２番目ばんめの男おとこはスペインの探検家たんけんかでした。↗

  The second man was a Spanish explorer.
• 探検者たんけんしゃ
  nounAlso a person who explores, but as a plain description of someone engaged in exploring, without the nuance that it is their profession; suits describing the members of a particular expedition.

For a person who explores unknown regions choose 探検家, which implies a profession or calling, or the more neutral 探検者; 「エクスプローラ」 is a loanword met mainly in software and product names rather than for people.
