Company information
Hoshia Electric has established itself as a top manufacturer in various business fields, including information display systems such as road information boards, industrial lighting known for its waterproof and explosion-proof features under the name "Water Pearl," tunnel lighting that began with the full-scale installation in the Kanmon Tunnel, and resin products represented by "Cutting Duct." As a new business, we started the electromagnetic noise countermeasure (EMC) product business in 1997 to address electromagnetic noise issues arising from digital devices. In the LED business, we successfully developed a blue light-emitting diode in April 2002 and a white light-emitting diode in December of the same year. Based on these technologies, we are actively expanding our business in the field of LED lighting fixtures, ranging from roads and tunnels to industrial lighting. On March 9, 2018, Hoshia Electric Co., Ltd. was listed on the First Section of the Tokyo Stock Exchange. In April 2022, we transitioned to the Tokyo Stock Exchange Standard Market. Moving forward, we will continue to leverage our unique creativity and technological capabilities cultivated over the years to develop even more innovative products and strive for business expansion.
