Kokichi Mikimoto, after successfully produced half spherical pearls in 1893, continued all effort to produce spherical pearls, and eventually succeded in 1905. The first five pieces of spherical pearl were found in mother-of-pearls which were treated by Otokichi Kuwabara, who was originally a dentist, and later joined with Mikimoto. He used his skill of dentist to insert pearl nuclei wrapped by the outer epithelial cells of the mantle piece. He also developed many operating tools, and this is the reason why pearl-operating tools widely used in the present-day cultured pearl fishery resemble dentist tools. Another important person in the early days of Japanese pearl fishery is Tatsuhei Mise, who developed different technique from that of Kuwabara. Mise's technique is to transplant, using a specially designed injection needle, the outer epithelical cells of the mantle piece, together with nucleus, into the gonad or mantle tissue. Because of Mikimoto's ability as businessman and organizer, of development of two different new techniques of pearl operation, and of support from scientists in universities, Japanese cultured pearl fishery developed rapidly, and production increased tremendousely. The Japanese cultured pearls gradually received recognition from the world jewellers, and their market expanded world-wide. Mikimoto's ability as PR man played important role in this respect, and he opened cultured pearl jeweller shops not only in Japan, but also in London, Paris and New York by the 1910.
