In 1910 Chiyoda Gas Co. was established and competed fiercely against incumbent Tokyo Gas Company fighting for gas lighting users. Tokyo Gas Industry was a parts supplier for Chiyoda Gas but it was defeated and merged into Tokyo Gas in 1912. Losing its largest client, Tokyo Gas Industry Co. broadened their product line including electronic parts, and renamed itself as Tokyo Gas and Electric Industry(東京瓦斯電気工業), TG&E and was often abbreviated as Gasuden. It produced its first motor vehicle in 1917, the Model TGE "A-Type" truck. In 1937, TG&E merged its automobile division with that of Automobile Industry Co., Ltd. and Kyodo Kokusan K.K., to form Tokyo Automobile Industry Co., Ltd., with TG&E as a shareholder. Four years later, the company changed its name to Diesel Motor Industry Co., Ltd., which would eventually become Isuzu Motors Limited.
