I have made a slight edit to the first paragraph of the page and plan to go over the rest of it a bit later to make additional edits as necessary. The first paragraph stated that Mikimoto invented the first technique for cultured pearl production. That is not true. The technique was introduced to Japan simultaneously by two Japanese men known as Tatsuhei Mise and Tokishi Nishikawa. They had both spent time in Australia, the same place William Saville-Kent was studying ways to culture pearls. Sawville-Kent produced whole, spherical pearls with a new method of inserting a bead and piece of mantle tissue into the reproductive organ of a host mollusk. It seems clear that Mise and Nishikawa brought this technique back to Japan. Mikimoto eventually patented this technique which he learned from Mise and Nishikawa and this is the technique still used today. That is why it is called the Mise-Nishikawa method. C. Denis George wrote a paper on this a few years ago.
