Course Taken Since the Company's Foundation Aiming to Become a Company that Can Contribute to Customers and Society
Since its foundation in 1905, the Group has striven to become a company that can solve social issues and contribute to society through the stable supply of reasonably priced city gas, sales of gas appliances, and the provision of diversified businesses and services, while competing with companies offering other fuels. Each Group company in its business field has consistently and sincerely tackled issues facing customers and society while upholding three slogans: “pursuit of business efficiency,” “contribution to society,” and “provision of solutions.” By doing so, the Daigas Group has won the trust of customers and society, and has strengthened its competitiveness.
Despite the needs of customers and society becoming increasingly diversified and complex, and competition intensifying, Group companies will work hard together and continue to provide solutions by presenting goods and services that can contribute to society.
History of Growth in the Daigas Group’s Businesses
The Daigas Group’s gas business began with gas supply in 1905. In over 110 years since, the gas business that started with lighting gas lamps has expanded the application of gas to cooking, heating, hot water, and power generation, overcoming many obstacles as society evolved and lifestyles changed. Additionally, founded on the relationships with customers and regions that have been fostered through the energy business, the Daigas Group has expanded its business domains and developed into a corporate group that provides various products, services, and solutions.

The Group's History Since its Foundation
1897: Osaka Gas was founded
1905: Osaka Gas launched its business by starting to supply gas
Iwasaki plant (located in then Iwasaki Town, currently part of Nishi Ward, Osaka City)
In the middle of the Meiji Era, fires caused by kerosene lamps frequently occurred in densely populated areas including Osaka. In those days, Osaka Gas, in a foundation statement presented to the authorities, pledged to disseminate kerosene lamps and electric lights by encouraging people to switch to those lighting devices from gas lamps. The pledge was part of the Company's activities to solve issues facing society at that time.
1933: “Osaka Gas Building” was completed
Osaka Gas Building
Osaka Gas Building, the head office building of Osaka Gas, was completed in Yodoyabashi, Osaka City. The building, which currently serves as the south building of the Osaka Gas head office, embodied the philosophy cherished by then Osaka Gas Chairman Naokata Kataoka. He said at that time that Osaka Gas must become known and loved by citizens through its gas business. He also said that Osaka Gas Building must act as a place of exchange between his company and citizens and serve as a place to bring citizens closer to the gas business. As pledged by Kataoka, Osaka Gas Building has become a base for promoting exchange with citizens, as well as a cultural dissemination center.
1945: Osaka Gas merged with 14 companies, including Kobe Gas and Kyoto Gas
Osaka Gas became a gas provider that catered to the six prefectures in the Kansai region.
1946: Osaka Gas formed its own labor union
In-house work rules for employees
In December 1945, a labor union was formed for employees working for the Iwasaki factory in Iwasaki Town, Osaka City. In February 1946, another labor union was formed, this time for employees working for the Kyoto branch, followed by one union after another at its respective business offices.
1970: Gas explosion occurred at a subway construction site
A large explosion involving gas supply facilities occurred in Osaka City. The accident killed 79 people and injured 420.
Immediately after the accident, Osaka Gas set up an emergency team to handle the provision of compensation to the victims' families and to investigate the cause of the accident. Following the accident, the Company strengthened its security and safety system to prevent similar occurrences in the future. Specifically, it established a department tasked with devising security measures and created a 24-hour control center to handle contingencies expeditiously and comprehensively. In 1972, the Company employed a large number of people fresh out of school and deployed many of them in departments related to gas pipeline operations. The deployment was intended to facilitate overall inspections of gas pipes and supply facilities, enhance the safety and security of engineering work, and strengthen patrols to detect engineering works that are conducted without notification to authorities.
1972: Commenced import of LNG from Brunei
“LNG FLORA” commenced its service
LNG is superior to other fossil energy sources in terms of environmental preservation, supply stability and economic efficiency. At that time, LNG was drawing keen attention as a next-generation energy source that could respond to the surging demand for city gas backed by the rapid urbanization of Japan and its booming economic growth.
Osaka Gas signed an agreement to purchase LNG from Brunei Cold Gas for 20 years in partnership with Tokyo Electric Power Co. and Tokyo Gas Co. With this agreement, Osaka Gas became the first Kansai-based company to import LNG.
1975: Commenced natural gas conversion
Himeji LNG Terminal
(Shown on the left is Kansai Electric Power Co.'s Himeji LNG terminal.)
Osaka Gas turned to high-calorie natural gas as its raw material to produce city gas, instead of relying on coal and petroleum for city gas production. In line with this policy change, the Company constructed LNG terminals, established LNG processing facilities and laid gas-supply facilities. In addition, Osaka Gas staff visited all of its customers' residences and sought their cooperation when the staff adjusted their gas appliances to prevent incomplete gas combustion. Osaka Gas replaced gas facilities at a total of 4.4 million households. The number of gas appliances at the households applied adjustment for conversion to natural gas came to 23 million units. Under a 16-year project that was concluded in December 1990 without a single accident.
