Due to strong sales in Japan, offers began to come in from overseas for the Casio 001 desktop electronic calculator. Seeing a good opportunity to expand abroad, Casio developed the Casio 101 with improvements for the overseas market, and in 1966 exported its first calculator to Australia. In the following year, Casio established a European office in Switzerland, followed by an overseas sales company in the US (Casio, Inc.) in 1970. In 1972, Casio established Casio Computer Co. G.m.b.H. Deutschland (now Casio Europe G.m.b.H.) in Germany, and the company began growing worldwide.
