Company information
Our company's history began on February 11, 1921, when our founder, Daisuke Hirai, established a sole proprietorship in Osaka. During World War II, we relocated to Kyoto at the request of Shimadzu Corporation, which was a military supply company for the nation. In February 1952, after the war, we established the current company, built and moved our headquarters and factory to Kyoto, and completed the technology for epoxy molded transformers. In August 2019, we opened a new production base called "Reiwa Keihanna Business Office." In 2020, we obtained ISO 9001 certification, and in February 2021, we celebrated our 100th anniversary by receiving the "66th Shibusawa Award" sponsored by the Japan Electric Association, marking the beginning of a new chapter for us. Furthermore, without resting on our laurels, we are committed to continuing the fusion of the achievements and technological innovations we have cultivated over the years, striving daily to create products that transcend traditional business fields. As a company, we aim to contribute to society by becoming an enterprise capable of supporting various "infrastructures" surrounding society, and we aspire to nurture the technology and talent that will carry "Japan's future."
