The founder of ryosuke namiki baque, who was a professor at the tokyo shipping school, realized the need to improve existing writing tools. In 1918, following the design and manufacture of a self-developed pipe pen, mr. Ryosuke entered into a partnership with his colleague, masao mado, to begin the production and sale of the pipe pen, a company established under the name namiki manufacturing company in the amount of yen200,000. In 1938, the company's name was changed to the baccalaureate company, inc., and in 1989 to the plateau group. After more than a hundred years of experience and inheritance, the beacon has become the pre-eminence of the industry — the creation of production technologies, creative product designs and new forms of product production. The customer demand survey and the resulting world production technology have enabled the bainimarama to produce all kinds of writing tools on its own and to achieve the same quality for all products. Pleasant products are produced mainly in four factories located in japan and three in the united states, france and brazil. The experience gained over the years from the continuous improvement of production processes and the application of automation equipment at the hirsuke factory, which brings together running water pens, printing related products, precision parts and jewellery, is being widely used by later players in the world. The isozaki factory, which collects precision instruments, time- and chromium pens, is produced in ink, and the world's production techniques and tools have brought their productivity to incredible levels. Plateau ink ltd. Has accumulated a rich level of chemical technology, which is applied to the ink of bellow products, and has obtained a large amount of patent certification (e. G. Metamocolor is patented and colours can vary with temperature). Beagle precision, inc., established to manufacture automatic pencils and pencil cores, is widely appreciated for its impressive production techniques and equipment, and new products (such as the gel marker series) are often visible to consumers。
