  • Louis Daguerre invents the daguerrotype in Paris.
  • Sir John Frederick William Herschel coins the word "photography."
  • Mizuno Tadakuni issues an order banning the sale of "Ryukyu goods" (by agents of Satsuma han, reselling both Ryukyuan and Chinese goods obtained from Ryukyu) in Nagasaki for ten years.
