Mikimoto Kōkichi (御木本 幸吉?, 10 March 1858 – 21 September 1954) was a Japanese entrepreneur who is credited with creating the first cultured pearl and subsequently starting the pearl industry with the establishment of his luxury pearl company Mikimoto.
His company was awarded patents for pearl cultivation and in 1985 to commemorate the 100th anniversary of the patent system he was selected as one of Japan's top 10 inventors. He was inducted into the house of peers by imperial decree and posthumously awarded the Grand Cordon of the Order of the Sacred Treasure. The Mikimoto company was ranked as one of the worlds most luxury brands by WWD and Mikimoto Kokichi was considered one of the best Japanese financial leaders of the 20th century by Nihon Keizai Shimbun. He is also known as the founder of Mikimoto Pharmaceuticals, a company specialising in beauty products containing pearl calcium. Mikimoto Pearl Island is named after him. In addition, the Phoenix Mikimoto crown used by former Miss Universe winners are credited to his patented work.
Born as the first son of an udon shop owner in Toba, Shima Province (present-day Mie prefecture), Mikimoto left school at the age of 13 and sold vegetables to support his family. Seeing the pearl divers of Ise unloading their treasures at the shore in his childhood started his fascination with pearls.
