  In 1950 the Ujiden Chemical Industry Co., Ltd. became the first company
in the world to succeed in making artificial emery. For over half a century the artificial emery has been widely used not only in Japan but abroad under the name "TOSA EMERY EXTRA". During this period it has developed into a general maker of abrasives. Currently they produce such products as media and compound, for barrel finishing and finishing machines.
