An exposition held in 1873 in Winn, the capital of Austria. This was the first exposition held by the Meiji government, although it had participated in a world exposition at the end of the Edo period. Since there were no new industries in Japan at the time, the main items on display were old crafts, but they immediately attracted the attention of Europeans, and Japan, which had been thought of as an undeveloped country, was instantly regarded as a country with an old culture, and the study of Japan was suddenly promoted. This was the beginning of the crafts trade, and in particular, apprentices dispatched to Japan on this occasion introduced various new technologies to Japan. In the field of ceramics and porcelain, such craftsmen as Notomi Keijiro, Kawahara Chujiro, and Tanzan Rikuro introduced to Japan the direct-heating cylindrical kiln, Western-style overglaze painting, plaster molds, and water metal.
