How to say "inventor" in Japanese

• クリエイターCommon
  nounCovers the loose sense of someone who creates or invents things, but its core meaning is 'creator', so it fits artists, designers and content makers more than a technical inventor.
• 元祖がんそCommon
  nounEmphasizes being the first: the originator or pioneer who started a dish, style or practice. For a person who invents machines or devices, 発明家 is the word.
• 発明家はつめいかCommon
  nounThe straightforward word for an inventor in the literal sense: a person who devises new machines, devices or techniques. For someone like Edison, this is the word you want.

  B. Franklin was an American statesman and inventor.
• 開祖かいそCommon
  nounReally means the founder of a sect, religion or school; it suits someone who originates such a tradition, and is seldom the word for a literal inventor of devices.
• 祖そCommon
  nounDenotes the originator, pioneer or founder of a school, art or tradition. Its 'inventor' sense is this abstract 'first one' idea; for someone who invents devices, 発明家 is the natural word.

Use 発明家 for an actual inventor of devices; 元祖, 開祖 and 祖 all point to the originator or founder of a style, school or tradition, while 「クリエイター」 is a broader loanword for a creator.
